To provide an elevator and a cam for limit switch actuation, by which emission of noise caused by contact between a limit switch and the cam for limit switch actuation can effectively be inhibited.SOLUTION: An elevator 1 according to the present invention includes: a car 20 elevating in a hoistway 10; a limit switch 60 provided in the hoist way 10; and a cam 65 for limit switch actuation provided in the car 20. The cam 65 includes an inclination cam 651 inclined relative to a traveling direction of the car 20, the inclination cam 651 being configured to actuate actuators 61, 62 of the limit switch 60. The inclination cam 651 is in the form of a concave shape bent or curved relative to a line L connecting a starting end 651a and a terminal end 651b of the inclination cam 651.SELECTED DRAWING: Figure 5

    【課題】リミットスイッチとリミットスイッチ作動用のカムとの接触に伴う騒音の発生を効果的に抑制することができるエレベータ及びリミットスイッチ作動用のカムを提供する。【解決手段】本発明に係るエレベータ1は、昇降路10内を昇降するかご20と、昇降路10内に設けられるリミットスイッチ60と、かご20に設けられるリミットスイッチ作動用のカム65とを備え、カム65は、かご20の進行方向に対して傾斜する傾斜カム651であって、リミットスイッチ60のアクチュエータ61,62を作動させる傾斜カム651を備え、傾斜カム651は、傾斜カム651の始端651aと終端651bとを結ぶ線Lに対して屈曲又は湾曲した凹状に形成される。【選択図】図5
