PROBLEM TO BE SOLVED: To provide a turning direction indicating device mainly used for various controls of a motor vehicle, which reduces loud sounds caused by a cam body and allows a coil spring to be easily mounted with a relatively quiet operation sound.SOLUTION: A locking portion 22E on both lateral sides of the undersurface of a cover 22 is formed in a shape of a rib with a substantially equivalent inclination according to the inclination of an engaging wind portion 16B of a coil spring 16, such that when the engaging wind portion 16B is locked to the locking portion 22E, the coil spring 16 is linearly arranged, without deformation in parallel with the arrangement of the locking parts 22E on both lateral sides, and the biasing force exerted by the coil spring 16 to a cam body 5 is applied uniformly in a lateral direction. As a result, sounds of collision of the cam body 5 with a release body 7 are made uniform, thus realizing a turning direction indicating device which reduces loud sounds caused by the cam body 5 and allows the coil spring 16 to be easily mounted with a relatively quiet operation sound.SELECTED DRAWING: Figure 1
【課題】主に自動車の各種制御用に用いられる旋回方向指示装置に関し、カム体による大きな発生音を抑制し、比較的静かな動作音で、コリルばねの取付けが容易な旋回方向指示装置を提供することを目的とする。【解決手段】カバー22下面の両側方の係止部22Eを、コイルばね16の係合巻き部16Bの傾きに応じて略同等の傾きのリブ状に形成し、係合巻き部16Bが係止部22Eに係止されることによって、コイルばね16は変形を生じることがなく、両側方の係止部22Eの配置と平行に直線状に配置され、コイルばね16によるカム体5に対する付勢力は左右方向に均等に加わるため、カム体5によう解除体7との衝突音が均等化されて、カム体5による大きな発生音を抑制し、比較的静かな動作音で、コイルばね16の取付けが容易な旋回方向指示装置を実現することができる。【選択図】図1
