As shown in FIG. 5, the bicycle (14) is a thin, flat and vertically long tubular body, and has a housing chamber (52) for housing the battery (10) therein. The upper end of the storage chamber (52) is open, and a lid for closing the opening (20) is provided at the front edge of the opening (20).
(22) is pivotally supported. When the opening (20) is closed by the lid (22), the storage chamber (52) is in a substantially sealed state, and entry of rain, dust, etc. is prevented. An input terminal (56) connected to the output terminal (54) of the battery (10) is provided on the front lower surface of the accommodation chamber (52). The input terminal (56) is electrically connected to the electric motor (12). A control chamber (58) having the control circuit therein is provided on the lower surface of the rear side of the accommodation chamber (52) in a protruding manner. battery
As shown in FIG. 5, (10) has a plurality of substantially cylindrical battery cells (11) laid sideways in the width direction of the bicycle,
The bicycles are arranged in the front-rear direction and the vertical direction, connected in series by wiring (11a), and surrounded by a metal plate (13) or a resin. When the battery cells (11) are housed in this way, a larger number of battery cells (11) can be housed as compared with the case where the battery cells (11) are vertically stacked vertically. The outer peripheral shape of the battery (10) is formed in a vertically long flat shape that is thin in the width direction of the bicycle according to the shape of the accommodation chamber (52). When the battery (10) is stored in the storage chamber (52), the output terminal (54) is provided at a position facing the input terminal (56) on the lower surface of the storage chamber (52), and the output terminal (54) is , Is electrically connected to the wiring that is the end of the series connection of the battery cells (11). The lower rear portion of the battery (10) has a concave shape according to the shape of the control room (58). By making the lower surfaces of the storage chamber (52) and the battery (10) into the above shapes,
The storage direction of the battery (10) can be regulated, and if the battery (10) is inserted into the storage chamber (52) with the front and back reversed, the control chamber (58) will be an obstacle and the battery (10) will be stored in the storage chamber. (52)
Not completely contained in. On the top of the battery (10),
A handle (60) for taking out the battery is formed. When taking out the battery (10), the handle (60) may be grasped and the battery (10) may be pulled out upward. Battery (10)
As shown in FIG. 4, the outer peripheral side surface is housed in a state in which the outer peripheral side surface is close to the inner surface of the housing chamber (52) with almost no gap over substantially the entire circumference. When the battery (10) is housed in this way, the strength of the battery (10) is added and the strength of the saddle mounting frame (18) is improved, so that the wall thickness of the saddle mounting frame (18) can be reduced. The portion surrounded by a circular frame in FIG. 4 will be described later.
