<p>PROBLEM TO BE SOLVED: To rotatably support a locking lever and a knob lever with the small number of part items and installing manhours, and to enhance force transmitting efficiency between both levers by relatively nonrotatably connecting the locking lever to a shaft part having the same axis as the rotary axis of the knob lever arranged on a knob lever. SOLUTION: A shaft part 96 having the same axis as the rotary axis of a knob lever 95 is integrally arranged by bearing the knob lever 95 to rotate according to operation of an operation knob in a lower part of a cover 33. A locking lever 32 to be fitted to the cover 33 is fitted to the cover 33 so as to check an axial directional movement by a connecting shaft part 96a formed in the shaft part 96 in a part corresponding to the inside of an actuation chamber 92. Therefore, the locking lever 32 is relatively nonrotatably connected to the shaft part 96, that is, the knob lever 95. Therefore, since the locking lever 32 and the knob lever 95 can be supported in common, both levers 32 and 95 can be rotatably supported with the small number of part items and installing manhours. Since both levers 32 and 95 integrally rotate around the same axis, force transmitting efficiency can be enhanced between both levers 32 and 95.</p> |
