Claims

[Scope of Claim for Utility Model Registration] (1) In a locking device for an automobile back door, the door closing mechanism is unlocked by unlocking a cylinder lock and pushing the cylinder lock forward. a cylinder lock that is provided to be movable forward and backward; and a cylinder lock that is provided within the main body of the device so as to be rotated in conjunction with the rotor of the cylinder lock and to be pushed by the forward movement of the cylinder lock;
and an interlocking member having a stopper protrusion around the periphery, a support member fixed within the main body of the device so as to slidably insert the interlocking member and support the interlocking member, and a support member for unlocking the cylinder lock. Therefore, when the interlocking member rotates and moves forward in conjunction with forward pushing of the cylinder lock, a hole provided in the support member through which the stopper convex portion passes; A spring receiving plate that slides against the interlocking member within the device body inside the support member and has the interlocking member inserted therethrough so as to rotate together, and the cylinder lock and the interlocking member are moved back. A spring member provided between the spring receiving plate to be moved and the interlocking member, an action spring provided between the above spring receiving plate and the support plate, and the above-mentioned door interlocked with the forward movement of the interlocking member. A locking device consisting of a pushing member that releases the locking of a closing mechanism. (2) The above-mentioned cylinder lock is equipped with a rotor that can be rotated counterclockwise and clockwise by a predetermined rotation angle from the key insertion position, and has a rotating force that always returns to the key insertion position when not in operation. , a stopper convex portion provided on the interlocking member faces so as to pass through the hole of the support member under the rotation of the interlocking member that is interlocked with the leftward rotation of the rotor, and the interlocking member that is interlocked with the rightward rotation of the rotor; A locking device according to claim (1) of the utility model registration, which is configured to shift from the opposing position of the hole portion under rotation of the locking member and prevent the interlocking member and the cylinder lock from advancing. (3) The rotor and the interlocking member are connected so that the interlocking member is interlocked with the rotation of the rotor after the majority of the left rotation and right rotation, and the rotation of the interlocking member causes the stopper convex portion to be moved. The locking device as set forth in claims (1) and (2) of the utility model registration, which faces the hole of the support member and is offset from the facing position.
