1. A brake apparatus for a vehicle, comprising:
a torque member to surround a brake disk;
a pair of brake pads disposed in the torque member in a way to face each other; and
a plurality of return parts mounted on the pair of brake pads, coupled with the torque member, guides movements of the pair of brake pads, and returns the pair of brake pads to their original positions by elastic restoring forces thereof,
wherein each of the plurality of return parts comprises:
a return mounting part mounted on one of the pair of brake pads;
a return spring connected to the return mounting part and returns the one of the pair of brake pads to its original position by the elastic restoring force thereof; and
a return coupling part connected to the return spring and coupled with the torque member,
wherein each of the pair of brake pads comprises:
a back plate on which the return mounting part is mounted; and
a friction member connected to the back plate and contacts the brake disk,
wherein the back plate comprises:
a back plate body with which the friction member is coupled; and
a pad protrusion protruding from each of both sides of the back plate body and having the return mounting part mounted thereon,
wherein:
the return mounting part includes one or more coupling holes, and
the pad protrusion includes one or more coupling protrusions coupled with the one or more coupling holes,
wherein:
the one or more coupling protrusions is a pair of coupling protrusions disposed in the pad protrusion in a way to be spaced apart from each other, and
a number of the one or more coupling holes is the same as a number of the one or more coupling protrusions,
wherein the return mounting part further comprises:
a first return mounting part connected to the return spring and faces a first surface of the pad protrusion;
a second return mounting part bending and extending from the first return mounting part in a way to face a second surface of the pad protrusion and having any one of a pair of the one or more coupling holes;
a third return mounting part bending from the second return mounting part to one side thereof and surrounds a third surface of the pad protrusion; and
a fourth return mounting part bending and extending from the third return mounting part in a way to face a fourth surface of the pad protrusion and having the other of the pair of the one or more coupling holes.
