Description

本開示の車両用ブレーキは、例えば、ホイールを制動すべく制動部材を移動させる作動部材と、モータと、上記モータによって回転される回転部材と、上記回転部材の回転に伴って直動し上記作動部材を移動させる直動部材と、上記回転部材と上記直動部材との間に設けられ、上記回転部材の軸方向への上記直動部材の移動により上記回転部材と上記直動部材とによって挟まれて上記軸方向に弾性変形される第一の弾性部材と、を備える。 The vehicle brake according to the present disclosure includes, for example, an operating member that moves a braking member to brake a wheel, a motor, a rotating member that is rotated by the motor, and a linear motion that accompanies the rotation of the rotating member. A linear motion member that moves the member, and is provided between the rotary member and the linear motion member, and is sandwiched between the rotary member and the linear motion member by the movement of the linear motion member in the axial direction of the rotary member. And a first elastic member that is elastically deformed in the axial direction.

上記車両用ブレーキは、第一の弾性部材を回転部材と直動部材とによって挟んで弾性的に圧縮する構成を有する。よって、例えば、第一の弾性部材の位置の制約によって他の部品も含めた部品のレイアウトの自由度が低下したり、第一の弾性部材の圧縮反力を受けるための剛性を高めるためにハウジングの厚みを局所的に増大したりといった、回転部材とハウジングとの間で第一の弾性部材が圧縮される構成によって生じていた不都合な事象を、回避できる。 The vehicle brake has a configuration in which the first elastic member is sandwiched between the rotating member and the linear motion member and is elastically compressed. Therefore, for example, a housing is used to reduce the degree of freedom in layout of parts including other parts due to the restriction of the position of the first elastic member or to increase the rigidity for receiving the compression reaction force of the first elastic member. It is possible to avoid a disadvantageous phenomenon caused by the configuration in which the first elastic member is compressed between the rotating member and the housing, such as locally increasing the thickness of the first member.
