PROBLEM TO BE SOLVED: To provide a disc brake improved in durability.SOLUTION: A disc brake 1 includes an annular plate 66 as a restriction member for restricting axial movement of each planetary gear 60 of a planetary gear deceleration mechanism 45, and an outer peripheral portion of the annular plate 66 is held between an annular face 71A of an internal gear 61 and a one-end side annular face 31B' of an inner side annular wall portion 31B of a first housing 31. Thus vibration of the annular plate 66 can be suppressed, engagement of each planetary gear 60 with the internal gear 61 and a sun gear 57 can be properly kept, and noise and the like can be suppressed. Further durability of the disc brake 1 can be improved.SELECTED DRAWING: Figure 1 |
