<p>Disclosed is a mechanism for releasing an excess load with a simple construction when the excess load is applied during a cancel operation for automatically restoring an operating lever (3). A movable member (9) is swingably supported by a holder (8) mounted to an operating lever (3) and a spring (6) is provided between the movable member (9) and a driving member, whereby the movable member (9) is biased toward the stable position of the holder (8), and the driving member is brought into press contact with a cam surface (10) of a case. When the operating lever (3) is rotated from the neutral position to the operating position, the driving member slides on the cam surface (10) and is held in the operating position, and a first lever member (4) comes into the rotation path of a cancel protrusion (4e). When in this condition the steering wheel is turned in the opposite direction, the cancel protrusion (4e) abuts the first lever member (4) to rotate during the return operation thereof, and with that, a second lever member (5) rotates. As a result, the periphery of an opening of the second lever member (5) pressurizes a receiving portion of the movable member, and due to this pressurizing force, the operating lever (3) is automatically restored to the neutral position. <IMAGE></p> |
