Japanese Patent JP7047333
Kind Code:
B2
Abstract:
To provide a return mechanism which is applied to an electrically-driven braking device and adopts a spiral spring, in which torque limit works properly.SOLUTION: An electrically-driven braking device comprises: an electric motor which presses a friction member onto a rotary member which is rotated integrally with a wheel; and a return mechanism which generates a return torque to the electric motor in a direction in which the friction member is separated from the rotary member when electric conduction of the electric motor is not performed. The return mechanism includes: "a spiral spring having a restraining part which is formed in such a manner that one end portion thereof is engaged with a rotary shaft driven by the electric motor, and the other end portion thereof, which is positioned on a side opposite to one end, is folded"; and a housing which stores the spiral spring, and has an inhibition face which contacts the restraining part. The other end is so configured as to be positioned on a side opposite to an axis with respect to an extension surface in which the inhibition face is so extended as to approach the axis.SELECTED DRAWING: Figure 6
