1. A gear comprising:
a gear body configured to be attached to a distal end of a driving shaft in an axial direction of the driving shaft and including teeth each extending obliquely with respect to the axial direction, wherein the driving shaft includes a D-cut portion at the distal end, and a round columnar portion adjacent to and on a proximal side with respect to a head of the D-cut portion, the round columnar portion having an outside diameter that is equal to or smaller than an outside diameter of the D-cut portion; and
a stopping portion included in the gear body and configured to allow the driving shaft to which the gear body is attached to move in a circumferential direction, wherein
when the driving shaft moves in the circumferential direction, the stopping portion is configured to stop the gear body from moving in the axial direction, the stopping portion stopping the gear body by coming into contact with a portion of the driving shaft,
the stopping portion has a through-hole into which the driving shaft is insertable, and
the stopping portion is configured to come into contact with the D-cut portion while allowing the driving shaft to move in the circumferential direction at the through-hole.
