Claims

[Scope of utility model registration request]

(1) In a disc brake having a cylindrical piston with a bottom, the opening end surface of the piston is formed into a ring shape from a metal material with low thermal conductivity, with a complete circle on the ring plane and a notch on the inner or outer periphery. At the same time, a plurality of through-holes made of incomplete circles opening in the shape of a ring are provided, and at the same time, a plurality of locking pieces are provided in pairs on the inner peripheral edge of the ring, diametrically opposed to each other.
and bending two opposing locking pieces of the locking pieces to form a contact portion forming a convex surface facing the inner circumferential surface of the piston;
A heat shield plate for a piston in a disc brake, characterized in that the contact portion is inserted into and locked to the inner circumferential surface of the piston.

(2) A heat shield plate is sandwiched and locked between a main heat shield plate having a locking piece and the main heat shield plate and the piston opening end surface, and is formed thinner than the main heat shield plate and is mainly formed on the ring plane. A heat shield plate for a piston in a disc brake according to claim 1 of the utility model registration, characterized in that the heat shield plate is formed in combination with a plurality of auxiliary heat shield plates formed with through holes smaller in diameter than the heat shield plate. .
