  Next, assembly of the support arm 6 to the leg member 5 will be described.

  First, as shown in FIG. 7, two peripheral members 30 are attached in the front-rear direction along the groove 22 on the lower surface of the support arm 6, and the support arm 6 is installed at a predetermined position on the upper surface of the leg member 5. As shown in FIGS. 8A, 8 </ b> B, and 9, the projecting pieces 30 c and 30 d provided at two locations on each peripheral member 30 are fitted into the fitting holes 22 c and 22 d of the groove portion 22, respectively. Thus, even if the lower surface of the support arm 6 to which the peripheral member 30 is attached is directed downward, the peripheral member 30 does not fall out of the support arm 6, and the peripheral member with respect to the fitting holes 22 c and 22 d of the support arm 6. Since the 30 protruding pieces 30c and 30d can be assembled to the leg member 5, the assembly efficiency of the entire desk 1 is improved. Thus, the peripheral member 30 is clamped by the support arm 6 and the upper surface 5a of the leg member 5 when the support arm 6 is attached.

  As shown in FIGS. 13 to 15, when the metal support arm 6 is installed on the upper surface 5 a that is the decorative surface of the wooden leg member 5 and the leg member 5 and the support arm 6 are attached by screwing means, If the support arm 6 formed of a rigid body is subjected to concentrated stress on the upper surface 5a of the wooden leg member 5, there is a risk that wrinkles and bending may occur, but the peripheral member 30 formed of an elastic member serves as a buffer member. The leg member 5 is prevented from being damaged or deformed.

  In particular, the groove portions 22 provided in the outer peripheral edge portion of the lower surface of the support arm 6 are provided in the outer peripheral edge and the front and rear peripheral edges, and the peripheral members 30 are arranged on the outer peripheral edge and the front and rear peripheral edges that are conspicuous from the outside of the furniture. By doing so, it is possible to reliably hide the bag etc. from the outside.

  Moreover, since the sectional view shape in the width direction of the peripheral member 30 is an inclined shape having an inclined surface 30b that expands toward the upper surface 5a of the leg member 5, the load of the support arm 6 and the top plate 2 applied from above is applied to the contact area. Therefore, the support arm 6 can be stably held.

  Further, as described above, the lower surface of the support arm 6 is installed on the upper surface 5 a of the leg member 5, and at the same time, the substantially isosceles trapezoidal fitting protrusion 28 of the support arm 6 is formed on the inner groove of the leg member 5. Approach and fit 5b. By fitting the fitting protrusion 28 into the fitting groove 5b, positioning in the front-rear direction and the left-right direction with respect to the leg member 5 of the support arm 6 is performed.

  After fitting the fitting protrusion 28 into the fitting groove 5b, the connecting bolt 34 inserted into the screw hole 28c of the fitting protrusion 28 is screwed into the leg member 5 (see FIG. 15), thereby supporting The fitting projection 28 of the arm 6 is fixed to the fitting groove 5 b of the leg member 5.

  Thus, the fitting protrusion 28 of the support arm 6 is fitted into the fitting groove 5b of the leg member 5, whereby the rigidity of the leg member 5 can be increased. Moreover, since both the fitting protrusion 28 and the fitting groove part 5b were made into the trapezoid shape which narrows toward the downward direction, it becomes easy to insert the fitting protrusion 28 in the fitting groove part 5b.

  Specifically, when the fitting protrusion 28 is inserted from the upper side toward the lower fitting groove 5b, the lower bottom side 28a, which is the narrow tip of the fitting protrusion 28, is fitted in the initial stage of insertion. It is easy to insert into the wide opening of the joint groove 5b, and thereafter, as the fitting protrusion 28 is inserted into the fitting groove 5b, the outer surface of the fitting protrusion 28 comes into contact with the inner surface of the fitting groove 5b and is gradually positioned. However, the fitting protrusion 28 is fitted at a predetermined fitting position.

  In addition, since the fitting groove 5b is opened upward as described above, the fitting protrusion 28 can be easily fitted into the fitting groove 5b.
