PROBLEM TO BE SOLVED: To restrain vibration of a hanger pin by simple construction and prevent stress from concentrating at one end of the hanger pin by interposing an elastic supporting member between the other end side of the hanger pin laid on both pad pressing parts and a pin insertion hole. SOLUTION: The acting parts 3a, 3b of a calliper body 3 corresponds to pad pressing parts, and a hanger pin 9 is inserted on the center of the upper parts of back plates 4b. The hanger pin 9 is constituted of a shaft part 9a and a male screw 9b on one end of the shaft part 9a, the outer circumference on the other end side of the shaft part 9a is formed with a recessed groove 9c, and an O-ring 10 equivalent to an elastic supporting member is fitted to the recessed groove 9c. Because on the other end side, the O-ring 10 elastically supports the shaft part 9a between the pin insertion hole 3j and it, even if vibration is transmitted to a disc brake 1, vibration of the hanger pin 9 is absorbed by the O-ring 10, and surplus stress is not generated in the male screw on the one end side. Hereby, durability of the hanger pin can be prevented from degrading.
