<P>PROBLEM TO BE SOLVED: To provide a valve device, in which a coil spring is incorporated efficiently and reliably. <P>SOLUTION: The valve device includes: a valve body 1 which has a recessed valve body accommodation chamber 8 and has a fluid inflow path 13 formed on the bottom part of the valve body accommodation chamber 8; a valve cover 2 which blocks the valve body accommodation chamber 8; a valve body 7 which is accommodated in the valve body accommodation chamber 8 and can open and close the fluid inflow path 13; a coil spring 14 which is fitted between the valve body 7 and the valve cover 2 in a compression deformation state and move-biases the valve body 7 to a closure position; and a sheet-like gasket 10 which is held between a valve body 1 and the valve cover 2, has a through-hole 15 through which the coil spring 14 can be inserted in the coil axial direction, and allows a plurality of protrusion pieces 16 for retaining the outer circumferential side of the coil spring 14 in the positioning state to be protruded along the peripheral edge of the through-hole 15. <P>COPYRIGHT: (C)2013,JPO&INPIT |
