In one example, the transmission unit 74 is displaced with respect to the housing 72 in response to the operation of the operation unit 60, and is provided so as to be in contact with the piezoelectric element 63 due to the displacement. The transmission unit 74 is housed in the housing 72.

As shown in FIG. 4, the piezoelectric element 63 includes a first electrode 63A and a second electrode 63B.

The first electrode 63A has a high potential when the state of the piezoelectric element 63 changes from a state in which no force is applied to a state in which a force is applied. The second electrode 63B has a low potential when the state of the piezoelectric element 63 changes from a state in which no force is applied to a state in which a force is applied.

The urging unit 76 applies a force that displaces the operation unit 60 to the first position P1 to the operation unit 60. The operation unit 60 is held at the first position P1 as a reference position by the force received from the urging unit 76 in a state where no force is applied. The operation unit 60 is displaced from the first position P1 to the second position P2 when a force resisting the force of the urging unit 76 is applied. The operation unit 60 is displaced from the second position P2 to the third position P3 when a force that opposes the force of the urging unit 76 is further applied.

When the operation unit 60 is arranged at the second position P2, the transmission unit 74 comes into contact with the piezoelectric element 63, and the piezoelectric element 63 generates a positive voltage. As shown in FIG. 3, the wireless communication unit 66A transmits the control signal S to the first control circuit 42A of the first transmission 42 once or a plurality of times by using the electric power supplied by the piezoelectric element 63. The gear ratio of the bicycle 10 is changed by the first control circuit 42A controlling the first motor 42C based on the control signal S. In one example, when the first shifting operation is performed, the gear ratio of the bicycle 10 is changed to be one step larger or smaller.

As shown in FIG. 5, when the operation unit 60 is present at the first position P1 and the second speed change operation for operating the operation unit 60 within the range of the second operation amount MB or more is performed, the operation unit 60 is performed. Is placed in the second position P2, the transmission unit 74 comes into contact with the piezoelectric element 63, and when the operating unit 60 is placed in the third position P3, the transmission unit 74 comes into contact with the piezoelectric element 63 again. Each time the transmission unit 74 comes into contact with the piezoelectric element 63, the piezoelectric element 63 generates a positive voltage. As shown in FIG. 3, the wireless communication unit 66A transmits the control signal S to the first control circuit 42A of the first transmission 42 once or a plurality of times each time power is supplied by the piezoelectric element 63. The first control circuit 42A controls the first motor 42C based on the control signal S, so that the gear ratio of the bicycle 10 is continuously changed. In one example, when the second shifting operation is performed, the gear ratio of the bicycle 10 is changed to be two steps larger or smaller.

When the transmission unit 74 separates from the piezoelectric element 63, a negative voltage is generated in the piezoelectric element 63. Since the anode 70A of the diode 70 is grounded, the negative voltage generated in the piezoelectric element 63 is reduced by the rectifying unit 68. Therefore, the negative voltage is less likely to remain in the piezoelectric element 63.
