PROBLEM TO BE SOLVED: To attain a vehicular brake having a new configuration in which it does not need a configuration, for example, in which a load torque of a motor is increased so as to detect a non-braking position.SOLUTION: The vehicular brake of this invention comprises, for example, a motion converting mechanism including a rotating member rotated in response to a rotation of a shaft that is provided with one thread part of a male thread and a female thread rotatably supported at a housing and rotated in response to a rotation of the shaft; and a direct-acting member supported at the housing in a direct-actable manner and under its restricted rotation, provided with the other thread part engaged with one thread part that is the other thread part of the male thread part and the female thread part and the brake member can be moved between a first position where the brake member brakes a wheel through direct-action as the rotating member is rotated and a second position where the braking against the wheel by the brake member is released, and the engaged state between the male thread part and the female thread part is released under a state in which the direct^action member is positioned at the second position.SELECTED DRAWING: Figure 5
【課題】例えば、非制動位置を検知するためにモータの負荷トルクを増大する構成が不要な、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、ハウジングに回転可能に支持され雄ねじ部および雌ねじ部のうち一方のねじ部が設けられシャフトの回転に応じて回転する回転部材と、ハウジングに直動可能にかつ回転が制限された状態で支持され雄ねじ部および雌ねじ部のうち他方のねじ部であって一方のねじ部と噛み合う他方のねじ部が設けられ回転部材の回転に伴って直動することにより制動部材がホイールを制動する第一の位置と制動部材によるホイールの制動が解除される第二の位置との間で移動可能な直動部材と、を有した運動変換機構と、を備え、直動部材が第二の位置に位置した状態では、雄ねじ部と雌ねじ部との噛み合いが解除されるよう構成される。【選択図】図5
