SOLUTION: A slider guide 34 is installed on the internal circumferences of leaf spring contacting pieces 21 furnished in a housing 30, and a slider 35 having slopes 36 at the front extremity is mounted movably longitudinally, and coil springs 37 expanding and contracting in the longitudinal direction are mounted behind the slider 35 so that the slider 35 is pushed forward. The slopes 36 are slidably contacted with the foremost extremities 24 of the leaf spring contacting pieces 21 so that they 21 are pushed toward the periphery, and thereby the protruding amounts of the contacting parts 23 toward the peripheries are adjusted. |
