<P>PROBLEM TO BE SOLVED: To prevent the generation of an abnormal sound generated when the coil part of a spring is butted to a support part according to the rotation of a rotary lever. <P>SOLUTION: A spring 4 is provided with: a coil part 41; and first and second arms 42 and 43 extended from the pertinent coil part to a tangential direction. The coil part 41 is supported around a support part 23 of a base member 2. The first arm 42 is extended along the moving orbit of an engagement protrusion 11 accompanied by the rotation of the rotary lever 1, and provided with a convex part 45 for engaging the rotary lever 1 to a direction where it is butted to a first stopper part 21 when the engagement protrusion 11 slides according to the rotation of the rotary lever 1, and when the rotary lever 1 is present at a first position, and for engaging the rotary lever 1 to a direction where it is butted to a second stopper part 22 when the rotary lever 1 is present at a second position. A second arm 43 is butted to a stopper part 24 for a spring formed in the base member 2 in such a state that a load is imposed in a direction where a coil part 41 is rolled in so that the inner peripheral face of the coil part 41 is pressurized to the side faced to the engagement protrusion 11 on the outer peripheral face of the support part 23. <P>COPYRIGHT: (C)2012,JPO&INPIT |
