In the second procedure, the battery unit 40 is rotated using the engaging portion 16 as a pivot so that the battery unit 40 is accommodated in the accommodation space DT1 of the down tube DT. Thereby, the battery unit 40 is arranged at the holding position. Then, the control section 32 controls the electric actuator 26 according to the detection result of the detection section 36, thereby displacing the lock section 24 from the unlock position to the lock position. Therefore, the terminal 44 of the battery unit 40 is electrically connected to the connector 30 , and the engaging portion 24C of the locking portion 24 is engaged with the engaged portion 42 of the battery unit 40 . The battery unit 40 is thereby locked to the battery holder 10 . The third procedure is to attach the cover CV 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 a fourth procedure, cover CV is removed from 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 section 32 controls the electric actuator 26 according to the release signal received via the receiving section 38, thereby displacing the lock section 24 from the lock position to the unlock position. Therefore, the battery unit 40 is unlocked, the battery unit 40 drops from the battery holder 10 , and the battery unit 40 is supported by the latch LT of the lock portion 24 . In a 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.
