<p>An electric braking device for a vehicle, wherein first and second guide members (GD1, GD2) are fixed parallel to each other, to a mount member (MTB) fixed to a support member supporting a wheel. A caliper (CPR) is supported by the first and second guide members (GD1, GD2) so as to be relatively movable in the axis line direction. An electric motor (MTR) is fixed to the caliper (CPR). Switching elements (S1-S4) for controlling the electric motor (MTR), an indicator (IND), and capacitors (CND1, CND2) are housed inside the caliper (CPR), and are positioned inside a guide quadrilateral (Mgd, quadrilateral A-B-C-D), when viewed from the vertical direction relative to the horizontal plane of the guide quadrilateral (Mgd), which has "as the four corners thereof both end points (A, B) of the first guide member GD1 and both end points (C, D) of the second guide member (GD2)." As a result, an electric braking device comprising an electric motor on the wheel side and a drive circuit therefor can be provided that has improved reliability of electronic components, such as a drive circuit, in relation to vibration during vehicle travel.</p> |
