<p><P>PROBLEM TO BE SOLVED: To provide an electric brake device, reducing dragging of a disc rotor and a friction member on the reaction part side to restrain uneven abrasion of a pair of friction members. <P>SOLUTION: This electric brake device includes: the paired friction members 4, 5 disposed in sliding contact with the disc rotor 6 from both the acting part 2 and the reaction part 3 of a caliper body 1; pressing members 7, 8 for pressing the friction members 4, 5 to the disc rotor 6; and a driving motor 14 provided on the acting part 2 side and causing the pressing members 7, 8 to generate pressing force. The acting part 2 includes a pair of driving shafts 12, 13 provided in the axial direction of the caliper body 1 to transmit the driving force of the driving motor 14 to the pressing members 7, 8, the paired driving shafts 12, 13 are formed in the reverse screw shapes different from each other in acting direction, and the driving force of the driving motor 14 can be transmitted to the acting part 2 and the reaction part 3 through a differential gear 11 by the paired driving shafts 12, 13. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
