2. Description of the Related Art There are first and second locking members attached to both ends of a watch band, wherein the first locking member includes a lock piece having a jumping-up portion integrated therewith, and a second locking member. Has a first operating member and a second operating member which are overlapped with each other and are movably opposed to each other so as to be movable in the width direction of the watch band. The first operating member includes a lock locking member for locking a lock piece. As an operation member, a middle clasp of a watch band having a raised end for pushing up the raised portion has been proposed in Japanese Patent Application Laid-Open No. 61-168302.

A first locking member and a second locking member, wherein the first locking member is pivotally attached to the watch band;
The second locking member comprises an elastic locking piece provided on the inside of the plate and a locking release piece having a slope, and one end of the second locking member projects from a window on one side, and the other end has a slope. A first operating member that has and is urged outward in the width direction by the first pressing means, and one end protrudes from the window on the other side,
The second operating member, which is urged to one side in the longitudinal direction by the second pressing means and has a regulating portion that regulates the operation of the first operating member in a normal state, and a locking piece of the first locking member are engaged. A clasp for a watch band, comprising a locking end to be stopped, wherein the slope of the unlocking piece and the slope of the first operating member are in contact when the locking piece and the locking end are locked. It is disclosed in Japanese Unexamined Patent Publication No. Hei 1-1121420.

According to this, the first operation member can be operated only when the second operation member is operated, and when the first operation member is operated, the slope of the first operation member is changed to the slope of the unlocking piece. Is pushed up to release the engagement between the locking piece and the locking end, so that the engagement between the first locking member and the second locking member is not easily released unless an intentional operation is performed. And the first
The operation member and the second operation member slide in the same plane, so that the clasp can be made thin.

しかし、第1の操作部材と第2の操作部材とが互いに
直交する方向に付勢されているので、第2の操作部材を
長手方向に摺動させながら第1の操作部材を幅方向に摺

Means for Solving the Problems In order to solve the above problems, the present invention comprises a pair of locking members which are detachably locked, and one of the locking members has a hook-shaped locking piece and a jumping member. Are provided at different places, and the other locking member is a clasp of a watch band provided with two operating members, and the other locking member is moved in the width direction within the same plane. A first operation member and a second operation member are provided, which are opposed to each other so as to be able to approach and separate from each other, and are respectively urged outward in the width direction. A lock engagement portion that is engaged with the lock piece and is released when the operation member approaches is provided, and a push-up portion that pushes up the lifting member when the operation member is close to the second operation member is formed. The push end and the lock are located at the opposite ends of the A notch portion into which the engagement portion is fitted is formed.

According to the clasp of the watch band of the present invention, the lock piece of one locking member faces the lock engaging portion of the other locking member, and it is easy to simply push down one locking member. Can be reliably engaged with the pair of locking members, and the first and second operating members can be disengaged simply by pushing the first and second operating members inward simultaneously in one operation, and the push-up portion jumps up. Since the locking member is raised by pushing up the part, the watch band can be easily removed without performing any special operation, and the operability is very good.

Further, the engagement between the pair of locking members can be released only when the two operating members are simultaneously pressed, and there is no fear that the clasp will come off unless an intentional operation is performed, and the safety is high. Furthermore, since the hook-shaped lock piece engages with the lock member to lock the pair of lock members, even if a large external force is applied, the lock can be easily released like a lock that is locked by a spring force. There is no fear that the engagement becomes loose due to the deformation of the locking portion.

In particular, since the first and second operating members are not overlapped and are disposed so as to be movably opposed in the width direction of the watch band in the same plane, the clasp is thinned, and the lock piece and the jumping-up member are used. In addition to being provided at a separate place, the opposed ends of the first and second operating members are formed with cutout portions into which the push-up portions and the lock engaging portions are fitted, so that the width of the clasp is narrow. It can also be used as a clasp of a watch band, especially a narrow watch band carried by a woman.

In addition, if the coil spring and the operation member are separated by the partition, the coil spring can be stably expanded and contracted without being displaced or coming into contact with the operation member.
