To provide a driving device of a vehicle seat which achieves high controllability and is inexpensive.SOLUTION: A driving device of a vehicle seat includes: a cylinder body 26 including a piston rod 11 connected to a vehicle seat 2; a hydraulic cylinder 12 having an oil chamber 13 and an atmospheric pressure chamber 30; an oil storage part 74 connected to the oil chamber 13 through an oil amount control unit 61; an air/oil pressure converter 16 having an air storage part 75; and a mechanical valve 4 (a switch valve) provided between the air storage part 75 and an air pressure source 67. The oil amount control unit 61 has a check mechanical valve 6 (an on-off valve) which opens or closes an oil passage 181 between the oil chamber 13 and the oil storage part 74. The check mechanical valve 6 includes: a check valve part 183 which allows a working fluid 31 to pass only from the oil storage part 74 side to the oil chamber 13 side; and an operation part 185 which operates the check valve part 183 so that the working fluid passes through the check valve part 183.SELECTED DRAWING: Figure 1

    【課題】制御性が高くかつ安価な車両用シートの駆動装置を提供する。【解決手段】車両用シート2に接続されたピストンロッド11を含むシリンダ本体26と、油室13と大気圧室30とを有する油圧シリンダ12を備える。油室13に油量制御装置61を介して接続された油貯留部74と、空気貯留部75とを有する空油圧変換器16を備える。空気貯留部75と空気圧源67との間に設けられたメカニカルバルブ4(切替弁)を備える。油量制御装置61は、油室13と油貯留部74との間の油通路181を開閉するチェックメカニカルバルブ6(開閉弁)を有する。チェックメカニカルバルブ6は、油貯留部74側から油室13側にのみ作動油31を通す逆止弁部183と、逆止弁部183を作動油が通過するように操作する操作部185とを備えている。【選択図】 図1
