<P>PROBLEM TO BE SOLVED: To provide a valve structure achieving improved assemblability and further preventing the occurrence of assembling failure. <P>SOLUTION: The valve structure includes: a valve disk 1 in which a port 2 is formed; a shaft member 5a rising from an axis part of the valve disk 1; a guide member 11 which is annular and is mounted on an outer periphery of the shaft member 5a and is layered on the valve disk 1; a main valve 13 which is annular and axially slidably mounted on an outer periphery of the guide member 11 and opens and closes the port 2; and an annular spring member 12 which is mounted on the outer periphery of the guide member 11 and biases the main valve 13 toward the valve disk. The valve structure also includes: a spring receiving member 14 integrally formed at an end of the guide member 11 opposite to the valve disk, for supporting an end of the spring member 12 opposite to the valve disk; and a flange 11a which is provided on an outer periphery of an end of the guide member 11 opposite to the valve disk and prevents the spring member 12 and the main valve 13 from slipping from the guide member 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
