Abstract
A disc brake device is configured to include friction pads facing the friction surface of a disc rotor, a caliper and a piston capable of pushing the friction pads against the friction surface of the disc rotor, and a mounting for supporting the caliper in a freely movable manner to a vehicle body side through a slide mechanism including a slide pin and a sleeve. A positioning mechanism capable of changing a relative position of the slide pin and the sleeve is arranged to appropriately change the position of the caliper according to the wear of the pad and ensure stable retract function.

A disc brake device comprising:
- a disc rotor that rotates about a rotation axis center;
- a friction pad that faces a friction surface of the disc rotor;
- a caliper capable of pushing the friction pad against the friction surface of the disc rotor;
- a mounting that supports the caliper in a freely movable manner to a vehicle body side through a slide mechanism including a slide pin and a sleeve;
- and
- a positioning mechanism capable of changing a relative position of the slide pin and the sleeve,
- wherein the positioning mechanism includes
- an accommodation groove formed on an inner peripheral surface of the sleeve,
- a movable element inserted in the accommodation groove and relatively movable with the slide pin, and
- an elastic member provided in the accommodation groove at an opening side thereof and adjacent to the movable element.
