Abstract
A radially biasing portion () of a pad spring () includes a first extending portion (A) extending from a lower surface plate (B) of a guide plate portion () outwardly in a disc axial direction, a curled portion (B) folded on a distal end side of the first extending portion, and a second extending portion (C) extending from the curled portion in a direction approaching a disc (), the second extending portion with which an ear portion (A) of a friction pad () comes into contact. A contact portion () extends from the second extending portion of the radially biasing portion () toward a middle of the friction pad in a disc rotational direction of the friction pad. The contact portion comes into surface contact with a contacted surface (B) as a lateral surface of the friction pad (backing plate) in the disc rotational direction.
