To provide a rotation/linear motion conversion mechanism of a novel structure with less inconvenience such as preventing a fastening state of a male screw and female screw from occurring, and a brake device.SOLUTION: A rotation/linear motion conversion mechanism comprises: a first rotary member that rotates around a central axis; a second rotary member that is rotatable relative to the first rotary member, has one screw of a male screw and a female screw meshing with each other, and is rotatable around the central axis in conjunction with the first rotary member; a linear motion member that has the other screw of the male screw and the female screw, and linearly moves according to the rotation of the second rotary member; and a torque limiter that has a first transmission surface provided on the first rotary member, and a second transmission surface provided on the second rotary member and contacting the first transmission surface, and is configured such that the first transmission surface and the second transmission surface slide when the transmission torque between the first transmission surface and the second transmission surface is equal to or greater than a predetermined value.SELECTED DRAWING: Figure 3
【課題】例えば、雄ねじと雌ねじとの締結状態が生じ難くなるような、より不都合の少ない新規な構成の回転直動変換機構およびブレーキ装置を得る。【解決手段】本開示の回転直動変換機構は、中心軸回りに回転する第一回転部材と、第一回転部材と相対的に回転可能であるとともに、互いに噛み合う雄ねじおよび雌ねじのうち一方のねじを有し、第一回転部材と連動して中心軸回りに回転可能な第二回転部材と、雄ねじおよび雌ねじのうち他方のねじを有し、第二回転部材の回転に応じて直動する直動部材と、第一回転部材に設けられた第一伝達面と、第二回転部材に設けられ第一伝達面と接した第二伝達面と、を有し、第一伝達面と第二伝達面との間の伝達トルクが所定値以上である場合に第一伝達面と第二伝達面とが滑るよう構成されたトルクリミッタと、を備えている。【選択図】図3
