Abstract
An actuator device for a rider-posture changing apparatus of a human-powered vehicle comprises a cam follower and a cam member. The cam member is rotatable about a rotational axis. At least one of the cam follower and the cam member includes a curved surface contactable with another of the cam follower and the cam member to move the cam follower in a movement direction in response to a rotation of the cam member. The movement direction is different from a circumferential direction defined about the rotational axis. The curved surface has a curved shape in a first cross-section perpendicular to the circumferential direction.

An actuator device for a rider-posture changing apparatus of a human-powered vehicle, comprising:
- a cam follower;
- and
- a cam member rotatable about a rotational axis defining an axial direction and a circumferential direction, at least one of the cam follower and the cam member including a curved surface contactable with another of the cam follower and the cam member to move the cam follower in a movement direction in response to a rotation of the cam member, the movement direction being different from the circumferential direction defined about the rotational axis,
- the curved surface having a curved shape in a first cross-section perpendicular to the circumferential direction.
