Abstract
A disc brake apparatus includes a boot including a fitting part. A slide pin is fixed to one of a support and a caliper and is slidably mounted to a guide hole formed in the other. Convex parts extending in a sliding direction of the slide pin are circumferentially arranged on an inner periphery of the fitting part. Concave recesses are respectively formed between the neighboring convex parts. Each of the convex parts is formed with at least one a low-height portion and a high-height portion in an axial direction of a rotor, respectively. Positions of the low-height portion and the high-height portion in a circumferential direction of the rotor are respectively different between the adjacent convex parts. The high-height portion has a height so as to contact the slide pin, and the low-height portion has a height so as not to contact the slide pin.
