Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a steering lock device for a vehicle, in which a steering shaft of a steering wheel is non-rotatably locked by a cylinder lock that operates an electric switch of an automobile engine. Among them, it particularly relates to a rattling prevention structure for a cylinder unit.

(Prior Art) In a steering lock device for a vehicle, a cylinder lock having a large number of parts and a complicated assembling property is separately incorporated into a cylinder lock outer cylinder as a unit as shown in Japanese Utility Model Publication No. 62-25960. It is designed to be assembled to the steering lock device in the final process. Conventionally, assembling of this cylinder unit is performed as shown in FIG.
With the engagement / disengagement pin 35, which is spring-biased so as to project outwardly on the outer periphery of the cylinder lock outer cylinder 34, is embedded in the recess 36 provided in the outer cylinder 34, the cylinder unit 37 is inserted into the case 38. By engaging the engaging hole 39 penetrating the case 38 with the recess 36 provided in the outer cylinder 34 and engaging the engagement / disengagement pin 35 with the engaging hole 39 of the case 38. Has been done.

(Problems to be solved by the invention) However, in the method of assembling the cylinder unit as described above, the shaft between the cylinder unit and the case may be different due to the dimensional variation of each member and the looseness of the engagement / disengagement pin and the engagement hole. A rattling occurs in the direction of rotation and the direction of rotation. By the way, for example, just before turning to the lock position
A solenoid integrated with a steering lock that drives the plunger to the suction position when the pushing operation at the ACC position and the vehicle speed is detected is provided, and a locking piece that interlocks with the plunger is attached to the engaging portion formed on the cylinder lock rotor. In the steering lock device that is engaged to prevent the rotor from rotating to the lock position, a switch for detecting the pushing operation of the cylinder lock rotor is provided on the case side of the steering lock device. When there is rattling in the axial direction between the case and the case, there is a problem in that the operating point of the switch varies and accuracy cannot be obtained. In addition, a locking piece that engages with an engaging projection of the cylinder lock rotor and restricts rotation of the rotor is pivotally supported on the case side, but there is a gap in the rotation direction between the cylinder unit and the case. If there is a rattling, there is a problem in that the engagement position varies, and accurate engagement cannot be performed. Further, the position of rotation of the rotor is detected by a movable contact arranged on the cylinder lock rotor side and a fixed contact fixed on the case side. When there is rattling, there is a problem in that the conduction position between the movable contact and the fixed contact varies, and the switch operation by rotating the rotor cannot be performed accurately.
