<P>PROBLEM TO BE SOLVED: To solve such a problem that a plunger cannot be incorporated unless cleaning inside of a guide pipe when assembling a drive unit into a conduit unit, in a solenoid valve, wherein the solenoid valve includes a plunger which slidably moves in the guide pipe in the cylindrical guide pipe, and at the same time, comprises the drive unit in which a solenoid coil is arranged outside of the guide pipe, and in which the plunger is moved reciprocatingly by controlling the current-carrying state to the solenoid coil, and the conduit unit in which the drive unit is attached, and wherein the solenoid valve changes the flow volume by changing the position of a valve element by pushing with the plunger, the valve element which increases/decreases the flow volume in the conduit being arrangedly provided in the midstream of the conduit formed in the conduit unit. <P>SOLUTION: A retaining member is attached in the outlet of the guide pipe, which protrudes inside from the inner peripheral surface of the guide pipe and prevents the plunger to slip out of the solenoid coil in a state before the drive unit is attached to the conduit unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
