This pneumatic control device (35) for vehicle seats comprises a pump control unit (35b), an opening and closing control unit (35c), and a residual pressure exhaust control unit (35d). The pump control unit (35b) drives a pneumatic pump (31) to force air into airbags (10, 20) provided within a seat (1). The opening and closing control unit (35c) opens and closes intake valves (42, 44) provided inthe air flow path communicating with the airbags (10, 20). After the the pneumatic pump (31) has stopped being driven, the residual pressure exhaust control unit (35d) opens an exhaust valve (43) provided upstream of the intake valves (42, 44) in the flow path, and thereby exhausts, from the flow path, the air trapped upstream of the intake valves (42, 44) in a closed position. 车辆座椅的空气压力控制装置(35)具备压送控制部(35b)、开闭控制部(35c)以及余压排气控制部(35d)。压送控制部(35b)通过驱动空气泵(31)向设置在座椅(1)的内侧的空气袋(10、20)压送空气。开闭控制部(35c)对设置于与空气袋(10、20)连通的空气的流路上的进气阀(42、44)进行开闭。余压排气控制部(35d)在空气泵(31)的驱动停止后，通过开放比进气阀(42、44)靠近流路的上游侧设置的排气阀(43)，从流路排出被密封于处于闭状态的进气阀(42、44)的上游侧
