PROBLEM TO BE SOLVED: To reduce cost by facilitating management of dimension accuracy in a tandem type negative pressure booster in which a tie rod inserted through a cylindrical sleeve fixed to a bulkhead plate to air-tightly penetrate a rear diaphragm ait-tightly penetrates a booster piston and a front diaphragm.SOLUTION: An annular locking flange part 65 bulging inward in a radial direction is integrally provided at one end of a sleeve 45 on a bulkhead plate 10 side so as to form a center hole 66 coaxial to the sleeve 45, a support cylindrical part 68 inserted through the center hole 66 is integrally provided in the bulkhead plate 10 that abuts against one end of the sleeve 45 via an annular sealing member 55, and the tip part 68a of the support cylindrical part 68 is engaged with the locking flange part 65.SELECTED DRAWING: Figure 2

    【課題】隔壁板に固定されて後部ダイヤフラムを気密に貫通する筒状のスリーブに挿通されるタイロッドが、前部ブースタピストンおよび前部ダイヤフラムを気密に貫通するタンデム型負圧ブースタにおいて、寸法精度の管理を容易とし、コストダウンを図る。【解決手段】スリーブ45の隔壁板10側の一端部に、半径方向内方に張り出す環状の係止鍔部65がスリーブ45と同軸の中心孔66を形成するようにして一体に設けられ、スリーブ45の前記一端部に環状のシール部材55を介して当接する隔壁板10に、中心孔66に挿通される支持筒部68が一体に設けられ、支持筒部68の先端部68aが係止鍔部65に係合される。【選択図】 図2
