PROBLEM TO BE SOLVED: To solve a problem that a beating sound is frequently generated at the time of switching a clutch means in a conventional rear wheel steering device. SOLUTION: The figure (a) shows the state of the steering device before operating a solenoid and when an energization is carried to the solenoid and an arm 58L shown by an imaginary line is rotated to the right, a trunk lever 60L is started to rotate to the left. The figure (b) shows a midway drawing and shows that the trunk lever 60L descends an operation element 31L along a vertical groove 72L as shown by an arrow by an action of the solenoid. The figure (c) shows the state that the solenoid completes the operation and a movement direction of the operation element 31L pushed by the trunk lever 60L is varied from a vertical direction to a lateral direction, thereafter it moves in a lateral groove 74L at a lower stage as shown by an arrow. An excess force of the solenoid is absorbed by moving the operation element in the lateral groove while swinging it. As a result, the operation element does not butt to a stopper, etc., and a generation of the beating sound can be prevented. |
