The invention provides a brake component of an elevator, which can restrain reduction of brake force generated by contact with a brake surface of a guide rail and restrain reduction of a function of repairing concave and convex parts generated on the brake surface. In the brake (132) of the elevator, a first friction part (22) and a second friction part (23) are arranged on opposite surfaces (211) of a brake main body (21). The second friction part (23) is located on the upper side of the first friction part (22). A second friction part (23) serving as a grinding tool part is provided with a second protrusion forming part (231) facing the braking surface (91), wherein a plurality of second protrusions (232) are formed on the second protrusion forming part (231). In the second friction section (23), the plurality of abrasive grains (234) are held by the binder (233). In the second protrusion forming portion (231), at least a portion of the plurality of abrasive grains (234) is exposed from the binder (233) as a plurality of second protrusions (232). The second protrusions (232) are smaller than the first protrusions (222) of the first friction part (22).
本公开提供一种电梯的制动件,其能够抑制与导轨的制动面接触而产生的制动力的降低,并且能够抑制对在制动面上产生的凹凸进行修复的功能的降低。在电梯的制动件(132)中,第一摩擦部(22)和第二摩擦部(23)设置于制动件主体(21)的对置面(211)。第二摩擦部(23)位于第一摩擦部(22)的上侧。在作为磨具部的第二摩擦部(23),朝向制动面(91)设置有形成有多个第二突起(232)的第二突起形成部(231)。在第二摩擦部(23)中,多个磨粒(234)保持于结合剂(233)。在第二突起形成部(231)中,多个磨粒(234)的至少一部分作为多个第二突起(232)从结合剂(233)露出。第二突起(232)比第一摩擦部(22)的第一突起(222)小。
