Patent ID: 8668067

Claim:
A vehicle parking lock device comprising: a parking rod that has a base end portion rotatably coupled to a detent plate, the parking rod being projected toward a leading end portion in association with rotation of the detent plate to a parking position; a tapered parking cam disposed at the leading end portion of the parking rod; and a cam guiding device that guides the parking cam moved together with the parking rod in association with the projection of the parking rod toward the leading end portion to move a parking lock pole rotatably disposed on a transmission case with the parking cam to a position of engagement with a parking lock gear rotated together with a transmission output member, the parking rod being projected from inside of the transmission case toward an opening portion of the transmission case, the cam guiding device including a first guiding member in a cylindrical shape that has an inner guiding surface guiding the parking cam, the first guiding member being fitted immovably in a direction orthogonal to a shaft center into a first receiving surface formed into a cylindrical surface shape within the transmission case, a second guiding member in a half cylindrical shape that is disposed subsequently to the first guiding member such that the second guiding member is received from a position on the side opposite to the parking lock pole by a second receiving surface formed adjacently in a shaft center direction to the first receiving surface within the transmission case and such that movement toward the parking lock pole is regulated by the first guiding member, the second guiding member having a tapered guiding concave surface that guides the parking cam toward the parking lock pole in association with the projection of the parking rod toward the leading end portion; and a fixing member that is fixed to the opening portion of the transmission case, the fixing member being engaged with an end portion of the second guiding member to regulate the rotation of the second guiding member around the shaft center and the movement toward the opening portion of the transmission case.
