PROBLEM TO BE SOLVED: To provide an atmospheric pressure type booster for improving manufacturing efficiency.SOLUTION: A sell body 2 is provided with a pressure introduction pipe 14 for supplying negative pressure to a constant pressure chamber A. The pressure introduction pipe 14 comprises a first pipe part 15 inserted into the constant pressure chamber A via a seal member 13, a second pipe part 16 for inserting a negative pressure supply hose 17 by extending in the predetermined angle direction to the axis O1-O1 of the first pipe part 15 and a flange part 18 formed in an intermediate part in the axis O1-O1 direction of the first pipe part 15 and regulating insertion into the constant pressure chamber A of the first pipe part 15. The shell body 2 is provided with a position display part 12 for displaying a position of the pressure introduction pipe 14, and the flange part 18 is provided with an allowable angle display part 19 for indicating an allowable angle in the extension direction of the second pipe part 16 to the axis O1-O1 of the first pipe part 15 to the position display part 12 displayed on the shell body 2. 【課題】製造効率を向上した気圧式倍力装置を提供する。【解決手段】シェル本体２には、定圧室Ａに負圧を供給する圧力導入管１４を設けている。圧力導入管１４は、定圧室Ａ内にシール部材１３を介して挿入される第１パイプ部１５と、該第１パイプ部１５の軸線Ｏ１−Ｏ１に対して所定の角度方向に延びて負圧供給ホース１７が差し込まれる第２パイプ部１６と、第１パイプ部１５の軸線Ｏ１−Ｏ１方向の中間部に形成され、第１パイプ部１５の定圧室Ａ内への挿入を規制する鍔部１８と、を有している。シェル本体２には、圧力導入管１４の位置を表示する位置表示部１２を設け、鍔部１８には、シェル本体２に表示された位置表示部１２に対して、第１パイプ部１５の軸線Ｏ１−Ｏ１に対する第２パイプ部１６の延出方向の許容角度を示す許容角表示部１９が設けられている。【選択図】図２
