Abstract: A profile radius change rate, which is an amount of change in a profile radius of a drive cam relative to a rotational angle of the drive cam in a pocket boundary section located between a progressively changing portion and a pocket portion, is set such that a boundary sound pressure, which is a sound pressure generated when a contact point between a roller and the drive cam passes through the pocket boundary section in response to the rotational movement of the drive cam, is included in a reference sound pressure range, which is a range of variation in a sound pressure generated when the contact point passes through the progressively changing portion.

Abstract: A driving device has a driving cam driven by a motor around a cam shaft, a roller which is in contact with the driving cam, a supporting frame, and a control shaft. The driving cam has a pocket portion. At the pocket portion, a profile distance from a center increases or decreases when the driving cam rotates in a normal direction or a reverse direction. When the pocket portion is in contact with the roller and the motor is stopped, the rotational force of the driving cam becomes zero. The rotational position of the driving cam and the axial position of the control shaft are held at a constant position. Thereby, the rotary place of the driving cam and the axial position of the control shaft component can be held in a fixed position.
