.. Are formed by pressing a metal plate, for example. As shown in FIG. 2, each of the leg pieces 192 buckles in a U-shape, and has a rectangular engaging part on its upper part which engages with each of the locking claws 146 protruding from the left and right side surfaces of the bracket body 140. Stop holes 193 are respectively formed.

Therefore, after the main bracket 150, the sub bracket 160, and the unit meter bracket 180 are mounted on the bracket body 140, the legs 192 of the clip 190 are fitted over the respective locking claws 146 of the bracket body 140 from above. Thus, the bracket 80 is assembled. clip
When 190 is put on, each leg piece 192 is attached to the bracket body 14
0 engages with each locking claw 146. Here, when the clip 190 is pushed downward, each clip 146 of the bracket 190 is pushed by each locking claw 146, and each leg 192 of the clip 190 flexes outward. When the locking holes 193 of the 192 are reached, each leg piece 192 snaps back, and each locking claw 146 fits into each locking hole 193, so that the clip 190 does not come off from the bracket body 140.

Also, by attaching the clip 190,
Since the open upper surfaces of the mounting grooves 141 and 142 and the insertion groove 143 of the bracket main body 140 are closed, the main bracket 150 and the sub bracket 160 inserted into the mounting grooves 141 and 142, and the unit meter bracket 180 inserted into the insertion groove 143. It will not come off. Next, a fuel transfer device having the above configuration
