<p>A roller assembly (100) having a rotating body (10), a drive wheel (20), a transmission receiving member (30), a frictional transmitting member (40), and an urging section (50). The rotating body (10) has a drive shaft (11) and a conveyance roller (12) provided to the drive shaft (11) and rotates on the axis of the drive shaft (11). The drive wheel (20) has a hole (21) through which the drive shaft (11) is inserted, is mounted to the drive shaft (11), and is rotationally driven. The transmission receiving section (30) is provided to the drive shaft (11), extends outward radially of the drive shaft (11), and rotates together with the drive shaft (11). The frictional transmitting section (40) is held between the transmission receiving section (30) and a side surface (22a) of the drive wheel (20) and frictionally transmitting rotational force of the drive wheel (20) to the rotating body (10). The urging section (50) urges holding force acting between the transmission receiving section (30) and the side surface (22a) of the drive wheel (20).</p> |
