An inflatable device includes a tubular body (31) fitted in a mouth (42) of an inflatable body (4) and having outer and inner end portions (314,318) respectively defining an adaptor port (312) and a valve seat (313) therein. A valve member (34) is movable between a closed position to be in air-tight engagement with the valve seat (313), and an open position to be disengaged from the valve seat (313) so as to permit inflation and deflation of the inflatable body (4) through the adaptor port (312). A plunger (32) has a plunger rod (322) connected to the valve member (34), and a plunger head (321) such that when an air supplying tube (51) of a pump (5) is inserted into the adaptor port (312) to force the plunger head (321) to move toward the valve seat (313), the valve member (34) is moved by the plunger rod (322) to the open position. A biasing member (33) is disposed to bias the plunger head (321) to hold the valve member (34) in the closed position. |
