The steering wheel lock has an alarm unit in connection to an actuation switch having a retractable button. An indirect transmission member has a spring biased drive pin the bottom of which can fall on a smooth front section or in a recess of the dentiform section of the lock stick so that the top end of the drive pin can be engageable with the retractable button of the actuation switch or can separate therefrom respectively.
