<P>PROBLEM TO BE SOLVED: To provide a technique for suppressing the increase in size of a work tool which drives a tip tool sandwich-held. <P>SOLUTION: By a biasing force of an O-ring 132 or a coil spring 134 arranged outside a spindle 120, an electric vibration tool 100 which holds a clamp shaft 123 arranged inside the spindle 120 is configured. By a thrust pin 140 which moves by revolution of a cam lever 150, the biasing force of the O-ring 132 or the coil spring 134 acting on the clamp shaft 123 is released, and the clamp shaft 123 can be removed. As a result, a blade 200 can be replaced without using a special tool. <P>COPYRIGHT: (C)2013,JPO&INPIT |
