    • A turning direction indicator device includes an actuator that rotates by an operation of the operating lever, a cam body that shifts in a rearward direction approaching a cancel cam. The cam body is rotatable about a rotation axis, and shifts in the rearward direction when the actuator rotates. The cam body includes a rear wall surface opposite to the cancel cam. The rear wall surface has two end parts symmetrical to each other with respect to the longitudinal axis. A spring elastically contacts the end parts to urge the cam body in the rearward direction. The spring also urges the cam body in a rotating direction about the rotation axis when the longitudinal axis of the cam body rotates. The turning direction indicator device suppresses a hitting noise produced by the cam body and a release element with such a simple structure, and operates reliably.
    • 旋转方向指示装置包括通过操作杆的操作而旋转的致动器,朝向接近取消凸轮的向后方向移动的凸轮体。 凸轮体可绕旋转轴线旋转,并且当致动器旋转时向后方移动。 凸轮体包括与取消凸轮相对的后壁表面。 后壁表面具有相对于纵向轴线彼此对称的两个端部部件。 弹簧弹性地接触端部以沿向后的方向推动凸轮体。 当凸轮体的纵向轴线旋转时,弹簧还沿旋转轴线沿旋转方向推动凸轮体。 转向方向指示装置抑制由这种简单结构产生的凸轮体和释放元件产生的打击噪音,并可靠地操作。
