In a window regulator 10, when a pin bolt 42 provisionally attached to a pulley 22 and a pulley support 54 is fastened to a door panel 14 by a nut 52, the pulley 22 and the pulley support 54 are supported on the pin bolt 42 and attached to a predetermined position on the door panel 14. Here, in the above-described provisionally attached state, the pin bolt 42 is held in the pulley 22 by pin member holding claws 74 of the pulley 22, and the pulley 22 is held in the pulley support 54 by pulley holding claws 68 of the pulley support 54. Consequently, when the pin bolt 42 is to be fastened to a body panel, the pulley 22, the pulley support 54, and the pin bolt 42 can be handled as a single part. Thus, the work of attaching a pulley and a pulley support to a body panel of a vehicle can be facilitated.
