<p><P>PROBLEM TO BE SOLVED: To provide an actuator of an inflating device, which hardly causes malfunction and can reduce effects on durability. <P>SOLUTION: The actuator 7 of the inflating device 1 includes: a hollow actuator socket; an actuator shaft 123; a flexible piece portion formed on one side of the actuator socket; a projection 133 having a mountain-like cross-sectional shape, which is formed on the flexible piece portion; a recess 145 having a valley-like cross-sectional shape, which is formed on the actuator shaft 123; a paper-made actuator roll 125 provided on the joint outside of the flexible piece portion of the actuator socket to regulate radially outward distortion of the flexible piece portion and swells with a liquid such as water; and a compression coil spring 147 which biases the actuator shaft 123 in such a manner that the projection 133 and recess 145 are disengaged and moved. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
