Abstract:
To provide an electric booster which can prevent co-rotation of an output member without preventing thrust of a thrust transmission member.SOLUTION: Flat surfaces 140, 141 defining a width of two surfaces of a two-chamfer shaft part 139 of an output piston 62 are slidably contacted with contact flat surfaces 142, 143 formed in an opening 138 of a thrust transmission part 82 of a power piston 81, thereby preventing co-rotation of an output piston 62. The output piston 62 is thus prevented from co-rotation without preventing thrust of the power piston 81.SELECTED DRAWING: Figure 4
