A disc brake is provided with: a brake mechanism that pushes a piston in a cylinder section by the driving of an electric motor and applies a braking force by pressing an inner brake pad and an outer brake pad against a disc rotor; and an elastic member that biases the inner brake pad and the outer brake pad in the axial direction of the disc rotor in a direction away from the disc rotor, the biasing force of the elastic member being set to be greater than the sliding resistance of the piston with respect to the cylinder portion. Therefore, dragging of the inner brake pad and the outer brake pad can be effectively suppressed.
盘式制动器具备:制动机构,所述制动机构通过电动马达的驱动来推进缸部内的活塞,通过将内制动衬块和外制动衬块按压于盘形转子来施加制动力;以及弹性部件,所述弹性部件在盘形转子的轴向上向从该盘形转子离开的方向对内制动衬块和外制动衬块施力,弹性部件的作用力被设定为比活塞相对于缸部的滑动阻力大。由此,能够有效地抑制内制动衬块和外制动衬块的拖曳。
