Claims

[Claims for Utility Model Registration] Engagement means that engages with a predetermined pressing force with the output shaft of a gear transmission mechanism capable of selecting a plurality of gear speeds and neutral, or with a part of a power transmission system connected to the output shaft. and a parking mechanism that restricts rotation of the output shaft or power transmission system by engagement of the engagement means, wherein the parking mechanism rotates in forward and reverse directions in response to pulse input from a power source, and the frequency of the pulse input is set to a predetermined frequency. A rotating means that generates the maximum output torque with the rotation when the frequency range is , a reducing means that reduces the rotation of the rotating means at a predetermined reduction ratio, and a rotating means that reduces the rotation from the reducing means in the direction of rotation. a converting means for converting the reciprocating motion into a reciprocating motion of a predetermined stroke according to the rotational speed and continuous rotation time; The pressing force decreases in force when the engaging means starts to engage, and the pressing force decreases in force when the engagement means starts to engage. detection means for detecting when the engagement of the engagement means is released; and detection means for detecting a stop of the vehicle based on the running state, and at the time of the stop, the stroke direction of the reciprocating motion is directed toward the engagement means; The rotation direction of the rotating means is controlled so that the rotation direction of the rotating means is controlled, and the frequency of the pulse input from the power source is kept within a predetermined frequency range from the start of engagement to the completion of engagement and from the completion of engagement to disengagement of the engagement means. A parking mechanism characterized by comprising: a control means for setting; and a parking mechanism.
