Parking lock-releasing device for vehicle

A parking lock-releasing device for a vehicle in which a parking mechanism actuated by an electric or hydraulic actuator unrotatably locks an output shaft of a transmission, the parking lock-releasing device being for manually releasing locking by the parking mechanism, comprising:

• an outer casing having an elongated hollow cylindrical shape;
• an inner cable accommodated in the outer casing such that the inner cable extends along a direction of length of the outer casing in a slidable manner, one end of the inner cable engaged with the parking mechanism;
• and
• a locking release operation section provided at a front end that is an end of the outer casing remote from the parking mechanism, for pulling the inner cable in a direction opposite to a direction toward the parking mechanism when manually releasing the locking,
• wherein the locking release operation section comprises:
• a base that has a guide portion having a hollow cylindrical shape and concentrically continuous with the front end of the outer casing, the guide portion having a female screw formed on an inner peripheral surface thereof;
• and
• an operating section body screwed via a male screw formed on an outer peripheral surface thereof into the female screw of the guide portion and also closes the guide portion, the operating section body holding another end of the inner cable, and when releasing the locking, being rotatingly operated in a predetermined direction relative to the base, to thereby cause the inner cable to slide such that the inner cable is pulled in the direction opposite to the direction toward the parking mechanism,
• wherein the operating section body comprises:
• a cable holder configured to extend concentrically with the guide portion over a predetermined length, and hold the other end of the inner cable in a state inserted in a through hole which extends along a direction of length of the cable holder, the cable holder having the male screw formed on an outer peripheral surface thereof;
• and
• a cover attached to the cable holder, in a state covering the front end of the cable holder and the other end of the inner cable,
• wherein an extremity of the other end of the inner cable is provided with an increased-diameter portion having a larger diameter than a diameter of the through hole of the cable holder, and
• wherein the operating section body further comprises a relative rotation holding section provided between the cable holder and the increased-diameter portion of the inner cable, for holding the cable holder and the inner cable in a state rotatable relative to each other.
