• wherein the main body comprises:
• a first surface facing a guide rail on which the carrier plate slides;
• a second surface placed on an opposite side of the first surface;
• and
• a side surface extending between the first surface and the second surface to face toward an outside to which the driving-force transmission member of which the end portion is held in the space region, the side surface including an opening portion provided spatially in communication with the space region, and
• wherein the opening portion:
• is a hole encircled by the side surface, and
• has a shape in which a pullout opening and an insertion opening are continuous to each other, the pullout opening having a first width where the driving-force transmission member can pass but the end portion does not, the insertion opening having a second width which is wider than the first width and where the end portion can pass.
