A vehicular electric lock device is provided in which a magnet is provided in a slider which is operated linearly in response to rotation of an electric motor and is operatively linked to a lock member, and a magnetic sensor detects by means of a magnetic field of the magnet that the lock member is in at least one of a lock position and a unlock position, wherein the slider comprises a screw-fitting member that is formed from a ferromagnetic material having rigidity and has a threaded shaft screwed thereinto and a magnet retaining member that is formed from a paramagnetic material, covers the screw-fitting member and retains the magnet, and the magnet retaining member is coupled to the screw-fitting member while preventing a relative movement in the direction along an axis of the threaded shaft and relative rotation around the axis of the threaded shaft.

Vehicular electric lock device

In a cylinder lock having a pivot member pivoted in response to pivoting by a legitimate mechanical key inserted into a key hole, a first rotor is linked to an outer cylinder relatively non-pivotably but movably along an insertion direction of a mechanical key, and a second rotor abuts against the first rotor from a side opposite to a rotor-receiving part provided on a housing and the outer cylinder and is linked to a pivot member relatively non-pivotably but movably along the insertion direction, and during pivoting of the outer cylinder in response to an unauthorized pivoting operation of an inner cylinder, the first rotor and the second rotor move so as to detach from the rotor-receiving part due to a cam mechanism provided between the first rotor and the housing, thereby releasing engagement of the inner cylinder with the second rotor linked to the pivot member relatively non-pivotably.

Cylinder lock

In a vehicle handle locking apparatus, a locking member that can operate between a locked position and an unlocked position and a holding member that operates together with the locking member are resiliently urged toward the unlocked position side; and an engaging member that engages with a holding member in the locked position and holds the locking member in the locked position is operated by operation of an electric actuator toward the side to release the engagement with the holding member. Forced unlocking drive device forcibly drives the holding member toward the unlocked position side in response to the operation of the electric actuator in a state in which the locking member is in the locked position. Accordingly, it is possible to provide a vehicle handle locking apparatus that releases, even when a force in a rotating direction is applied to a steering handle, engagement of a locking member with the steering handle or a linkage member so that an unlocked state is reliably achieved.

Vehicle handle locking apparatus

A cylinder lock capable of normal unlocking operation by an authorized key to a locking mechanism which has been illegally operated by an unauthorized key or the like, the cylinder lock comprising an engaging portion that engages a rotor in the rotational direction only when the cylinder moves toward the unlocking member is disposed to a cylinder to engage the rotor and the cylinder thereby rotating the rotor upon subsequent insertion of an authorized key to connect the rotor and the connection member thereby enabling normal unlocking operation.
