PROBLEM TO BE SOLVED: To restrain a striking sound generated when an input member collides with a housing, when releasing operation of a brake pedal, by improving detection accuracy in a reciprocating stroke of the input member.SOLUTION: A booster 1 of brake force of the present invention comprises an input member 4 for driving a master cylinder by boosting operation force of a brake pedal 100 in response to a movement quantity of the input member 4 for reciprocatably moving by the operation of the brake pedal 100, connecting one end to the brake pedal 100, inserted/fitted into a control housing 3 arranged in a housing 2 and relatively slidably provided in the axial direction and damping members 22, 31 and 32 provided in a position capable of connecting to or abutting on a part of an abutting part or an input member between the input member 4 and the housing 2, and when the input member 4 moves for returning when releasing the operation of the brake pedal 100, when the input member 4 abuts on the housing 2, the damping members 22, 31 and 32 are constituted so as to execute the impact absorbing damping action.SELECTED DRAWING: Figure 3
【課題】入力部材の往復ストロークの検出精度が良く、ブレークペダルの操作解除時等に入力部材がハウジングに衝突することによって発生する打音を抑制する。【解決手段】本発明のブレーキ力の倍力装置1は、ブレーキペダル100の操作によって往復移動する入力部材4の移動量に応じて該ブレーキペダル100の操作力を倍力してマスタシリンダを駆動するもので、ブレーキペダル100に一端が連結され、ハウジング2内に配設された制御ハウジング3内に挿嵌されて軸方向に相対スライド自在に設けられる入力部材4と、該入力部材4とハウジング2との当接部位又は入力部材の一部に連結又は当接可能な位置に設けられる減衰部材22、31、32と、を備え、ブレーキペダル100の操作解除時に入力部材4が戻り移動するとき、入力部材4がハウジング2に当接する際に、減衰部材22、31、32が衝撃吸収減衰作用を実行するように構成されている。【選択図】図3
