Abstract
Protruding portions protruding in a direction of approaching a disc rotor are integrally formed in a locking plate portion of a pad spring. Moreover, an insulating resin coating is formed on a front surface side (surface in a region opposed to an outer peripheral surface of the disc rotor) of the locking plate portion. The coating film formed on the front surface of the locking plate portion flows downward by its own weight before the coating material is solidified. As a result, the coating film formed on bottom surfaces (front surfaces of protrusions) of the protruding portions is thinner in film thickness than that of the coating film in other region.
Claims8
A pad spring to be installed in a disc brake, the pad spring comprising a locking portion to be locked to a mounting member to be mounted to a non-rotational portion of a vehicle,
- wherein the locking portion includes a coating film having a thinner coating film thickness in at least a part of a region opposed to a disc rotor than a coating film thickness in other regions of the locking portion.
A disc brake, comprising:
- a mounting member, which is to be mounted to a non-rotational portion of a vehicle, and is formed so as to straddle an outer peripheral side of a disc rotor;
- a pair of friction pads configured to be pressed against both surfaces of the disc rotor;
- and
- a pad spring, which is mounted to the mounting member, and is configured to elastically support a corresponding one of the friction pads,
- wherein the pad spring includes a locking portion configured to lock the pad spring to a portion of the mounting member that straddles the outer peripheral side of the disc rotor, and
- wherein the locking portion includes a coating film having a thinner coating film thickness in at least a part of a region opposed to the disc rotor than a coating film thickness in other regions of the locking portion.
