PROBLEM TO BE SOLVED: To provide a tandem type negative pressure booster which secures an effective stroke of a seal part to a side such that the seal part reduces the volumetric capacity of a front negative pressure chamber and enables reduction of an entire length in a direction along an axis of a tie rod.SOLUTION: An annular seal part 64, which slidably contacts with an outer periphery of a tie rod 56 at a side located closer to a front operation chamber 17 than a front booster piston 14 in an airtight manner, is integrally formed with a front diaphragm 15. An extension portion 64c which is formed so as to be partially inserted into a sleeve 45 is integrally formed with the seal part 64.SELECTED DRAWING: Figure 2

    【課題】前部負圧室の容積を縮小する側へのシール部の有効ストロークを確保しつつ、タイロッドの軸線に沿う方向での全長を短くするタンデム型負圧ブースタを提供する。【解決手段】前部ダイヤフラム15に、前部ブースタピストン14よりも前部作動室17側でタイロッド56の外周に気密に摺接する環状のシール部64が一体に形成される。またシール部64にスリーブ45内に一部が挿入されるようにした延出部分64cが一体に形成される。【選択図】図2
