PROBLEM TO BE SOLVED: To provide a negative-pressure type assistor which has good assemblability when a booster is fitted to a bearing member of a vehicle.SOLUTION: A negative-pressure type assistor is equipped with: a booster shell which is fitted to a bearing member of a vehicle; a front shell and a rear shell constituting the booster shell, in which at four corners of a flat part of the rear shell, projections which respectively project rearwards are fixedly provided; and a connection bolt in which said projections are inserted into continuously provided holes of the bearing member. The connection bolt is configured from an upper connection bolt which is located above a center axis of the booster shell and a lower connection bolt which is located below the center axis of the booster shell, and one of the projections of the upper connection bolt is extended rearwards with respect to the other projection of the upper connection bolt and each projection of the lower connection bolt.SELECTED DRAWING: Figure 1
【課題】ブースタを車両の支持部材に取り付ける際の組付け性がよい負圧式倍力装置を提供すること。【解決手段】車両の支持部材に取り付けられるブースタシェルと、ブースタシェルを構成するフロントシェルとリヤシェルと、リヤシェルの平坦部の四隅には、該平坦部から後方に夫々突出する突出部が固設され、当該突出部が支持部材の連設孔に挿通される連結ボルトと、を備える負圧式倍力装置であって、連結ボルトは、ブースタシェルの中心軸線より上側に配設される上側連結ボルトと、ブースタシェルの中心軸線より下側に配設される下側連結ボルトとから構成され、上側連結ボルトの何れかの一方の突出部は、上側連結ボルトの他方の突出部及び下側連結ボルトのそれぞれの突出部より後方に延出していることを特徴とする。【選択図】図1
