Document Type and Number:
Japanese Patent JP4119229
Kind Code:
B2
Abstract:
An electric parking brake mechanism characterized in an electric parking brake for pressing a friction member to a braked member via a force transmission converting mechanism for converting a rotational movement of an electric motor to a linear movement, including an input shaft connected to a side of the electric motor, an output shaft connected to a side of a brake mechanism for pressing the friction member to the brake member and a cam mechanism interposed between the input shaft and the output shaft, the cam mechanism is provided with a plurality of cam members and each having a cam face having a radius gradually increasing relative to a rotational center and in driving only a side of the output shaft, rotation of the output shaft is hampered by operating all of the plurality of cam members to constitute sides of large diameters.
