<P>PROBLEM TO BE SOLVED: To provide an electric booster enabling a correct adjustment of a spring set load of an input rod when adjusting a clevis during the starting operation of a system. <P>SOLUTION: During the starting operation of the system, thrust from an electric motor 33 based on a stroke detection value assists the driver operation force. An electric booster braking device includes: the clevis 12, to which a brake pedal 10 is connected through a pin; the input rod 15 screwed to a clevis screw part 82 of the clevis 12; a flange 60 screwed to the input rod 15 through a flange screw part 83; a primary piston 54 disposed in an outer peripheral position of the flange 60; a pair of springs 61 and 62 interposed in an axial clearance between a recess 54a of the primary piston 54 and the flange 60; and a groove part 80 and a brim part 81 provided between the primary piston 54 and the flange 60 so that the flange 60 is fitted therein to stop the rotation of the flange 60 during the starting operation of the system, without fitting before starting the system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
