PROBLEM TO BE SOLVED: To provide a sudden rotation stopper whose reliability can be improved.SOLUTION: A first member 50 comprises a first slope 54 that rotates integrally with the first member 50, the first slope being provided in a spiral shape around an axial center of the first member 50. A second member 60 comprises a second slope 63 in a spiral shape, the second slope being in surface contact with the first slope 54 in the axial direction. When the second slope 63 is pushed by the first slope 54, and a force in the axial direction acts on the second member 60; the second member 60 is received by a reception member 11. The second slope 63's coming into surface contact with the first slope 54 at the time of the first member 50's stopping makes it possible to make the first member 50 and second member 60 be hardly damaged, making it possible to improve reliability.SELECTED DRAWING: Figure 2
【課題】信頼性を向上できる急回転停止装置を提供すること。【解決手段】第１部材５０は、第１部材５０と一体的に回転する第１傾斜面５４が、第１部材５０の軸心の回りに螺旋状に設けられる。第２部材６０は、第１傾斜面５４と軸方向で面接触する螺旋状の第２傾斜面６３を備えている。第２傾斜面６３が第１傾斜面５４で押されて第２部材６０に軸方向の力が作用すると、第２部材６０が受部材１１によって受け止められる。第２傾斜面６３は、第１部材５０が停止するときに第１傾斜面５４と面接触するので、第１部材５０や第２部材６０を破損させ難くすることができ、信頼性を向上できる。【選択図】図２
