Claims

[Scope of utility model registration request]

A first brake lever and a second brake lever are supported on the vehicle body side, are arranged at opposing positions, and are relatively rotatable via a lever pin; a pad member extending from the axle side and pressing both sides of the brake rotor;
A link mechanism having a configuration in which the tip portions of the first lever and the second lever, which are pivoted to a pair of mounting pins provided at the other ends of the brake lever and the second brake lever, are connected by a connecting pin while maintaining a crossing angle. , a disc brake comprising a link mechanism driving means that expands and contracts the link mechanism to press and separate the pad member from the brake rotor side-2, and a return spring that biases the pad member in a direction in which the pad member separates. A spring is provided between the pair of mounting pins, and on an extension of the connecting pin located approximately at the center of the link mechanism. A disk characterized in that a guide member having a concave groove substantially matching the shape thereof is fitted and mounted, and an end surface of the guide member comes into contact with a side surface of the return spring at substantially the wear limit of the pad member. Brake pad wear detection mechanism.
