However, in this configuration, since the electrical terminals 32 (32A and 32B) for discharging are provided on the upper portion of the battery device 30, the configuration of the battery mounting portion 15, particularly the lower support portion 16 of the battery device 30 can be simplified. Thus, there is an advantage that the upper portion of the drive unit can be prevented from becoming large and can be made compact.

  Moreover, according to the said structure, the connection stand 18 which covers the lower pipe 2g while connecting the upper support part 17 and the lower support part 16 to the battery mounting part 15 which mounts the battery apparatus 30 is provided. Thus, the battery mounting unit 15 can mount the battery device 30 in a good posture. In addition, it is possible to differentiate the electric bicycle 1 by printing various characters and figures such as the company name and vehicle type of the electric bicycle 1 on the side surface of the coupling stand 18. In addition, since the connection wiring 25 connected to the power receiving electrical terminal 21 (21A, 21B) or the like is passed between the coupling base 18 and the lower pipe 2g, the connection wiring 25 is exposed to the outside. Therefore, the connection wiring 25 can be protected and the reliability can be improved. Moreover, since the connection wiring 25 cannot be seen from the outside, there is also an advantage that the appearance of the electric bicycle 1 is improved. In addition, by configuring the connecting base 18 as a separate component from the upper support portion 17 and the lower support portion 16, it is possible to easily print various characters and figures such as the company name and vehicle type of the electric bicycle 1, It becomes possible to select the connection stand 18 in an individual color, and to make the design stand out as the electric bicycle 1. However, the present invention is not limited to this, and the case forming the outer shell of the upper support portion 17, the case forming the outer shell of the lower support portion 16, and the connection base 18 may be integrally formed.

  Further, the connecting base 18 may not necessarily be provided as the battery mounting portion 15, and the battery mounting portion 15 may be configured by only the upper support portion 17 and the lower support portion 16 as shown in FIG. 16. In this case, it is preferable to pass the connection wiring 25 connected to the power receiving electrical terminal 21 (21A, 21B) or the like through the lower pipe 2g. According to this configuration, the connection wiring 25 can be prevented from being exposed to the outside, the connection wiring 25 can be protected, and the reliability can be improved. Moreover, since the connection wiring 25 cannot be seen from the outside, there is also an advantage that the appearance of the electric bicycle 1 is improved. Further, by not providing the connecting base 18, there is an advantage that it is possible to suppress a protruding dimension upward from a pipe body such as the lower pipe 2g.

  Moreover, according to the said structure, the elastic body 40 is attached to the center part of the battery apparatus 30, and the battery apparatus 30 contacts the connection stand 18 via the elastic body 40 at the time of mounting | wearing.

It will come into contact with force. Thereby, even when the electric bicycle 1 vibrates during traveling, the battery device 30 is favorably supported by the elastic body 40 and in a state where there is no backlash. In addition, a hole for passing the elastic body 40 may be formed in the coupling base 18 so that the elastic body 40 contacts the lower pipe 2g. Further, instead of attaching the elastic body 40 to the battery device 30, the elastic body 40 may be attached to the connecting base 18 or the lower pipe 2 g so as to be able to contact the battery device 30.

  In addition, according to the above configuration, the battery device 30 is provided with the electrical terminals 32 (32A, 32B) for discharging at the upper part away from the lower engaging portion 16b and the lower engaged portion 31 that become the rotation center when mounted. In addition, power receiving electrical terminals 21 (21A, 21B) are disposed at locations corresponding to these electrical terminals 32 (32A, 32B). In addition, the discharge electrical terminals 32 (32A, 32B) and the power receiving electrical terminals 21 (21A, 21B) are in a linear direction in contact with the rotational direction in which the battery device is mounted (in this embodiment, the left-right direction). It is arranged along. As a result, the radius of rotation when the electric terminal 32 (32A, 32B) for discharging is mounted on the electric terminal 21 (21A, 21B) for receiving power is provided at the lower part of the battery device. Since it is larger than the case, the change in angle when the electric terminal 32 (32A, 32B) for discharging enters the electric terminal 21 (21A, 21B) for receiving power and is brought into contact with the electric terminal 32 is minimized. Therefore, the dimension of the hole 30a in the vicinity of the electric terminal 32 for discharging (the dimension in the direction corresponding to the thickness of the electric terminal 21 (21A, 21B) for receiving power) can be reduced, and it is difficult for dust to enter. In addition, the deformable dimensions of the discharge electrical terminals 32 (32A, 32B) at the places where the electrical terminals 21 (21A, 21B) for receiving the electrical terminals 32 (32A, 32B) for discharge are inserted are reduced. The electric terminal 32 for discharge (32A, 32B) and the electric terminal 21 for power reception (21A, 21B) can be satisfactorily connected while being able to be suppressed.

  Further, since the mounting guide portion 29 is provided in the upper portion of the electric terminal 32 (32A, 32B) for discharging in the upper part of the battery device 30, rain or the like is discharged when the battery device 30 is not mounted. It becomes difficult to apply to the terminal 32 (32A, 32B), thereby improving the reliability. Also, a mounting guide 29 is provided, and when the battery device 30 is mounted, the electrical terminals 32 (32A, 32B) and the signal terminals 33 are used for receiving the electrical terminals 21 (21A, 21B) and the signal terminals 22 (22A, 22B) is adjusted and connected to the optimum position, and this also improves the reliability.

  In addition, according to the above configuration, the locking engagement portion 27 that locks the battery device 30 is disposed so as to be freely retractable on both sides of the lateral guide rib 26 </ b> A as a guide portion, and is engaged with the upper engaged portion 34.
