Abstract

A drive unit (20) is attached to a bracket (125) in a stable manner even when the bracket has a high stiffness. The housing (21) of the drive unit includes a first suspension boss (216L) and a second suspension boss (216R). The first suspension boss and the second suspension boss are located between the first side plate (1251) and second side plate (1251) of the bracket as determined along the left-right direction with respect to the bicycle (10). A first bolt (60) is fastened to the first suspension boss. The first bolt is inserted into a hole (1254) provided in the first side plate from the outside as determined along the left-right direction with respect to the bicycle. An insertion hole (2163) is provided in the second suspension boss. The insertion hole extends in the left-right direction with respect to the bicycle and is open toward the second side plate. A cylindrical member (56) is fitted into the insertion hole and is positioned to be slidable in a direction in which the insertion hole extends. A thread groove is provided on the inner periphery (561A) of the cylindrical member. The thread groove engages a thread provided on the outer periphery of a second bolt (62). The second bolt is inserted into a hole (1254) provided in the second side plate from the outside as determined along the left-right direction with respect to the bicycle.
