ABSTRACT:
A tire air valve (core) mounting and dismounting tool 20 includes a tool head portion 21, a shank portion 22 and a grip portion 23. The tool head portion 21 has a slot 32 for seizing and holding a valve core head portion 16, an axial bore 33 for accepting a valve core shaft portion 14 and its enlarged end 14a. The tool head portion 21 also has annular groove 34 formed along a cylindrical peripheral surface thereof. Balls 36 are retained in second bores 35 which are open to the annular groove 34 and also communicate with the axial bore 33 through openings 37 of a reduced diameter to allow the balls 36 to partially protrude into the axial bore 33. A coil spring 38 is anchored and fastened in the annular groove 34 to act to normally bias the ball 36 radially inwards and leave the balls 36 protruding into the axial bore 33. When the balls 36 are hit and pushed down by the valve core shaft's enlarged end 14a, the elasticity of the coil spring 38 allows the balls 36 to move radially outwards, permitting the valve core shaft end 14a to move deeper beyond the balls 36 and then permitting the balls 36 to restore their biased state, thereby holding the valve core shaft end 14a against moving back. Thus, the valve core is caught by the tool.
