摘要： A pin slide-type floating disc brake includes a mount, a caliper, one of which has a slide hole, a support pin provided to the other one and slidably inserted into the slide hole, and a tubular pin boot covering a part of the support pin. The pin boot includes a pin-side annular seal portion, a slide hole-side annular seal portion, and an extendable tubular bellows portion connecting those seal portions. The outer peripheral part of the slide hole-side annular seal portion includes an elastic restriction portion to elastically restrict movement of the slide hole-side annular seal portion in a rotor shaft direction, in an annular accommodation groove. The inner peripheral part of the slide hole-side annular seal portion includes, a first annular lip portion on a bellows portion side, and a second annular lip portion which has a retraction function on an opposite side to the bellows portion.
