Beschreibung
Zusammenfassung:	A power transmission mechanism for transmitting a driving force from a drive shaft (33) to a driven member (36) of a gear via a one-way clutch (35) is provided. The one-way clutch (35) includes a swinging clutch portion (53) swingably fitted in a clutch portion housing groove (54) formed in a first end portion of the drive shaft (33). The swinging clutch portion has a cylindrical portion (51) as the axis of rotation and a projecting portion (52). When the drive shaft rotates, the projecting portion (52) of the swinging clutch portion is raised by a slit (56) of a collar (55) fitted onto the drive shaft, engaging one of a plurality of engaging grooves (57) formed in the inner peripheral surface of the driven member. When the drive shaft does not rotate, the swinging clutch portion lies down, and the projecting portion does not engage any engaging groove, allowing the driven member to rotate bidirectionally relative to the drive shaft.
