A guide cam device includes a cam groove, a projection, and a restriction member. The cam groove includes: first, second, and third grooves, the second and third grooves branching forward from the first groove; and a locking recess positioned between a forward end of the second groove and a forward end of the third groove. The projection is configured to move forward and backward in the cam groove and enter a locked state upon entering the locking recess. The restriction member is configured to inhibit entry of the projection from the first groove to the third groove and permit the projection to advance from the first groove to the second groove. In response to being pushed by the projection that exits the locking recess and moves backward in the third groove, the restriction member is deformed or moved to enable the projection to move to the first groove.

A cam mechanism used is provided with: a cam ring forming a circle around an axis and including a plurality of cam faces arranged circumferentially on a face of the circle facing in an axial direction, each of the cam faces sloping in a circumferential direction relative to a circumferential face perpendicular to the axis; a pressure ring adjacent axially to the face of the cam ring and including a plurality of cam faces opposed to the face of the cam ring and respectively symmetrical to the plurality of cam faces of the cam ring, the pressure ring being rotatable relatively to the cam ring about the axis; and a plurality of taper rollers interposed between the cam ring and the pressure ring, each of the taper rollers including a conical face tapering radially inwardly and capable of rolling on the cam faces.

A camshaft contains a support tube, on which components including at least one cam are arranged at predetermined locations. The support tube extends at least partially through a hole in the components, and wherein a press fit is produced between the support tube and the components by hydroforming. Accordingly, at least one locally formed material formation is provided between the support tube and the hole. Via the material formation, the component is retained at the location in a desired orientation relative to the support tube in such a way that the support tube having the mounted components can be fed for hydroforming.

An apparatus for an actuating mechanism comprises a first member having a first axis; the first member has a generally spherical surface on a first half of the first axis and a generally ellipsoidal surface on a second half of the first axis. The first member is rotatable around a centerpoint of the first axis. A second member has a second axis and a generally ellipsoidal surface. The second member matingly engages the first member at the first member ellipsoidal surface and has a torsion spring coupled to the second member. The first member is actuated manually to move the second member. The torsion spring torque increases as the first member is rotated.

An exemplary drive selector includes a housing, a cam positioned in the housing, a follower coupled to a shaft and in contact with the cam, and a biasing member urging the cam toward the follower. One of the cam and the follower includes at least one protrusion, and the other of the cam and the follower includes a plurality of recesses configured to receive the protrusion. When the protrusion is received in the recess, the force provided by the biasing member resists relative rotation of the cam and the follower.

The invention relates to a camshaft comprising a support shaft formed as a hollow shaft. An inner shaft is arranged concentrically in the interior of the support shaft, wherein the inner shaft is rotatable relative to the support shaft. There is arranged on the support shaft a first cam segment with a first recess for receiving the support shaft, which cam segment is rotatable with respect to the support shaft and is connected in a rotationally conjoint manner to the inner shaft via a first opening in the support shaft. The first cam segment has at least two cam contours. The connection between the inner shaft and the first cam segment is furthermore configured such that the first cam segment is axially displaceable relative to the inner shaft and to the support shaft.

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.
