<p><P>PROBLEM TO BE SOLVED: To provide a valve element attachment structure to a channel forming member, suppressing complication and enlargement of the structure, and performing a predetermined operation and positioning of a valve element by a simple operation. <P>SOLUTION: This structure is provided with a locking projecting part 24 formed on the outer surface of the valve element 2, and a fixture 3 having first and second supporting piece parts 31a, 31b and forming a clearance 32 and passages 33a, 33b. With the locking projecting part 24 positioned in front of the second support piece part 31b, when the valve element 2 is rotated so that the locking projecting part enters into the clearance 32 and offset from the passages 33a, 33b of the fixture 3, the retreat of the valve element 2 is regulated by abutting the locking projecting part 24 on the second support piece part 31b. With the locking projecting part 24 positioned in the rear of the second support piece part 31b, when the valve element 2 is rotated so that the locking projecting part is offset from the passages 33a, 33b, the advance of the valve element 2 is regulated by abutting the locking projecting part 24 on the second support piece part 31b. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
