PROBLEM TO BE SOLVED: To provide an assistor comprising a resistance force application mechanism of which credibility is enhanced while suppressing large-sizing thereof.SOLUTION: A resistance force application mechanism 80 adopted in this assistor comprises: a slide member 81 which is slidably supported between a first shank 3E1 and a second shank 3E2 in a housing 3; a first compression spring 82 which is supported on the housing 3 and energizes the slide member 81 to a brake pedal side (rear side); and a second compression spring 83 which is supported on an input rod 30, and energizes the slide member 81 to a side (front side) opposite to an energization direction by the first compression spring 82. Thus, credibility of the resistance force application mechanism 80 can be enhanced while suppressing large-sizing thereof.SELECTED DRAWING: Figure 2
【課題】大型化を抑制しつつ、信頼性を向上させた抵抗力付与機構を備える倍力装置を提供する。【解決手段】本倍力装置に採用した抵抗力付与機構80は、ハウジング3内の第1胴部3E1と第2胴部3E2との間に摺動可能に支持される摺動部材81と、ハウジング3に支持され、摺動部材81をブレーキペダル側(後方側)に付勢する第1圧縮バネ82と、入力ロッド30に支持され、摺動部材81を第1圧縮バネ82による付勢方向と反対側(前方側)に付勢する第2圧縮バネ83と、を備えている。これにより、抵抗力付与機構80の大型化を抑制しつつ、その信頼性を向上させることができる。【選択図】図2
