ABSTRACT:
A turn signal cancel device includes a body to which is mounted a bracket including an operation lever and a back plate mounted thereto. In the bracket, there are provided balls and, if the balls are engaged with a moderation member, then the bracket can be held at its right turn direction position. Also, a ratchet is disposed in the body and, if the ratchet is rotated, then the surface to be pressed of the back plate is pressed by the pressure surface of the ratchet so that the bracket is rotated and returned to its neutral position. In this case, the ratchet includes an inclined pressure surface and, as the ratchet is rotated, the contact portion between the pressure surface of the ratchet and the surface to be pressed of the back plate is moved from a point .alpha. in the ratchet to a point .alpha.'.
