Claim Text:
1. An electric parking brake adapted for use with a brake disk, the brake disk having a rotating axis and opposite first and second end surfaces perpendicular to the rotating axis, said electric parking brake comprising: a main body unit including first and second side seats adapted to be located respectively at two sides of the brake disk and adjacent respectively to the first and second end surfaces, said first side seat having a first recess adapted to be disposed in proximity to the first end surface, said second side seat having a second recess adapted to be disposed in proximity to the second end surface; wherein said second braking member and said connecting member of said braking unit are formed as one piece, said support being connected fixedly to said connecting member, one of said first side seat and said support having two guide holes, the other of said first side seat and said support including two guide rods that are inserted respectively and movably into said guide holes and that extend along said axial direction, so as to guide movement of said support on said first side seat along said axial direction; wherein said first side seat is formed with a shaft hole extending along said axial direction, said driving shaft of said actuating unit extending through said shaft hole in said first side seat along said axial direction; and wherein said actuating unit further includes a bushing disposed on said support in such a manner that movement of said bushing on said support along said axial direction is prevented, said driving shaft extending rotatably through said bushing, each of said bushing and said driving shaft having a flange, said flanges of said bushing and said driving shaft abutting against each other so as to allow for synchronous movement of said flanges during rotation of said driving shaft relative to said main body unit.
