Actuator for ignition operation

An ignition operation actuator comprising:

• a drive section comprising a motor and a rotation transmission coupling;
• a flexible shaft that is rotationally driven by the drive section;
• an operation section mounted to a tip end portion of the flexible shaft so as to pressingly operate a push start ignition of a vehicle, wherein
• the operation section comprises a press button that presses the push start ignition, a motion conversion mechanism configured to convert rotation of the flexible shaft into a linear motion of the press button, and a holder to which the press button and the motion conversion mechanism are mounted,
• the motion conversion mechanism comprises a cam that is rotated about a rotation shaft so as to press a cam engagement portion disposed on a back face side of the press button,
• an axial direction of the rotation shaft is perpendicular to a direction of the linear motion of the press button,
• the tip end portion of the flexible shaft is detachably connected to an adapter disposed on the holder, and rotation of the flexible shaft is transmitted to the rotation shaft of the cam via a rotation transmission mechanism,
• the cam is provided with a cam follower that is brought into contact with the cam engagement portion and presses the cam engagement portion;
• a spring that urges the press button to return to an ignition press release position in which the push start ignition is released from a pressing force applied to the push start ignition by the press button, when the cam engagement portion is released from pressing by the cam follower;
• and
• an operation button rotation inhibition pin provided in a slit in the press button, the operation button rotation inhibition pin being a transverse pin with respect to the press button.

• the cam follower is constituted of a first cam follower disposed on an end portion of one side of the cam with respect to the rotation shaft of the cam, and a second cam follower disposed on an end portion of the other side of the cam with respect to the rotation shaft of the cam, and
• the cam engagement portion comprises a first cam engagement surface opposed to the first cam follower so as to be pressed by the first cam follower, and a second cam engagement surface opposed to the second cam follower so as to be pressed by the second cam follower, the first cam engagement surface and the second cam engagement surface each being formed into an inclined surface inclined in such a direction that as a distance on the inclined surface which extends from a central portion of a boundary between the first cam engagement surface and the second cam engagement surface toward a side of the cam engagement portion increases, the inclined surface is gradually spaced apart from the corresponding cam follower.
