Claims

[Scope of Claim for Utility Model Registration] (1) A main body having an air supply path from an air supply source to an inflatable life preserver, and a main body provided so as to be able to reciprocate so as to come into contact with a seat surface provided in the air supply path. a bottomed actuating tube; a first spring that presses the bottom of the actuating tube in a direction to press the seat surface; and an operating shaft that is reciprocably provided within the actuating tube and has an operating portion that protrudes outside the main body. A second spring is inserted between the actuating cylinder and the operating shaft to press the actuating cylinder against the seat surface and in a direction that causes the operating part to protrude outside the main body; a ball provided movably between the inner surface and the outer surface of the operating shaft; a locking portion formed on the inner surface of the main body to prevent the ball from moving in the direction of pressing the first spring; An air filling device comprising: a ball accommodating portion formed on the operating shaft side so as to accommodate the ball when the operating shaft is pushed in. (2) Utility model registration claim 1, characterized in that the first spring has a spring constant that is smaller than the pressure of the air supply source, and the second spring has a spring constant that allows the operating shaft to be pushed. charging device.
