Claims

[Scope of claim for utility model registration] If the ignition key is not in the lock position of the starting switch, the ignition key cannot be pulled out, and if the shift lever is not in the parking range, the ignition key cannot be pulled out. In a key interlock device that prevents a key from rotating to the lock position, the starting switch rotates integrally with a rotation axis that is linked to rotation of the ignition key. A stopper cam is provided, and a lock member that swings in a plane substantially perpendicular to the rotation axis is disposed, and as the lock member swings, a stopper portion formed on the lock member advances and retreats within the rotation range of the stopper cam. Normally, the stopper part enters the rotation range of the stopper cam to prevent rotation of the rotation shaft, and in conjunction with switching the shift lever to the parking range, the stopper part moves into the rotation range of the stopper cam. 1. A key interlock device, wherein the locking member is retracted from the stopper portion, and a swing axis of the locking member is disposed approximately on a normal line to a point of contact between the stopper cam and the stopper portion.
