To obtain a vehicular brake having an improved new configuration in which, for example, a piston easily follows a return of a linear motion member.SOLUTION: The disclosed vehicular brake includes: a rotation linear motion conversion mechanism having, for example, a normal rotation restriction part provided in a piston to restrict a normal rotation of a linear motion member and a reverse rotation restriction part provided in the piston to restrict a reverse rotation of the linear motion member; and an engagement mechanism including a first engagement part provided in the piston, and a second engagement part provided in the linear motion member to become an engagement state in which the first engagement part and the second engagement part overlap in a first direction while the reverse rotation restriction part restricts a reverse rotation of the linear motion member, and become a non-engagement state in which the overlapping of the first engagement part and the second engagement part in the first direction is released by causing a rotation member to perform a normal rotation from the engagement state.SELECTED DRAWING: Figure 3
【課題】例えば、直動部材の戻りにピストンが追従しやすいなど、改善された新規な構成の車両用ブレーキを得る。【解決手段】本開示の車両用ブレーキは、例えば、ピストンに設けられ直動部材の正転を制限する正転制限部と、ピストンに設けられ直動部材の逆転を制限する逆転制限部と、を有した回転直動変換機構と、ピストンに設けられた第一係合部と、直動部材に設けられた第二係合部と、を有し、逆転制限部によって直動部材の逆転が制限されている状態では第一係合部と第二係合部とが第一方向に重なった係合状態となり、係合状態から回転部材が正転することにより第一係合部と第二係合部との第一方向の重なりが解除された非係合状態となる、係合機構と、を備える。【選択図】図3
