<p>PURPOSE:To operate an operation lever regardless of the position of a steering wheel by bringing a ratchet section into contact with a cancel cam, and rotating a cam cylinder when the operation lever is operated to the right turn or left turn direction position from the neutral position in a specific state. CONSTITUTION:When a steering wheel 28 is slightly rotated to the left turn direction, for example, prior to the action of an operation lever 9, a cancel cam 21 is moved in the rotation locus of ratchet sections 8a of a ratchet 8. When the operation lever 9 is rotated to the left turn direction position L, for example, from the neutral position N under this condition, the ratchet sections 8a are brought into contact with the cancel cam 21, and a cam cylinder 20 is rotated against a spring member. The ratchet sections 8a are moved to the cancel position without being impaired by the cancel cam 21. The operation lever 9 can be operated to the right turn or left turn direction position L, R from the neutral position L regardless of the position of the steering wheel 28.</p> |
