To provide a battery attaching/detaching structure in a motor-assisted bicycle which is simple, can facilitate attaching and detaching of a battery case, and can reliably lock the battery case. [Constitution] In a motor-assisted bicycle having a battery and a motor to be driven by electric power of the battery and generate motive power assisting man power; a battery attaching/detaching structure comprising a battery case 23 for storing the battery, the battery case 23 being configured in the form of elongated box having a substantially quadrangular cross section; a body cover 27, 28, 29 provided obliquely along a down frame extending rearward and downward from a head pipe, the body cover 27, 28, 29 having a recess alpha substantially U-shaped in side elevation, for fittedly supporting the battery case 23, the recess alpha having an elongated inclined bottom surface opposed to an elongated lower surface of the battery case and front and rear inside surfaces respectively opposed to front and rear end surfaces of the battery case 23; and a lock device 26 for disengageably engaging a front end of the battery case 23; wherein the rear inside surface 29c of the recess alpha of the body cover is steeply inclined at an acute angle near a right angle with respect to the inclined bottom surface of the recess alpha ; and an angle of the rear end surface of the battery case 23 with respect to the lower surface of the battery case 23 is equal to the acute angle of the rear inside surface of the recess alpha with respect to the bottom surface of the recess alpha of the body cover. <IMAGE> |
