In the second procedure, the battery unit 40 is turned using the engaging portion 16 as a turning fulcrum so that the battery unit 40 is housed in the housing space DT1 of the down tube DT. Thereby, the battery unit 40 is arranged at the holding position. Then, when the control unit 32 controls the electric actuator 26 according to the detection result of the detection unit 36, the lock unit 24 is displaced from the unlock position to the lock position. For this reason, the terminal 44 of the battery unit 40 is electrically connected to the connector 30, and the engaging portion 24 </ b> C of the lock portion 24 is engaged with the engaged portion 42 of the battery unit 40. As a result, the battery unit 40 is locked to the battery holder 10. In the third procedure, the cover CV is attached to the battery unit 40. The third procedure may be performed before the first procedure. The battery unit 40 is attached to the battery holder 10 by the above procedure.

  The battery unit 40 is removed from the battery holder 10 through the following procedure, for example. In the fourth procedure, the cover CV is removed from the battery unit 40. In the fifth procedure, a release signal is transmitted from the external device ED1 by operating the external device ED1. Then, the control unit 32 controls the electric actuator 26 according to the release signal received via the receiving unit 38, whereby the lock unit 24 is displaced from the lock position to the unlock position. For this reason, the lock of the battery unit 40 is released, the battery unit 40 falls from the battery holder 10, and the battery unit 40 is supported by the latch LT of the lock portion 24. In the sixth procedure, the battery unit 40 is removed from the latch LT. The fourth procedure may be performed after the sixth procedure. The battery unit 40 is removed from the battery holder 10 by the above procedure.
