PROBLEM TO BE SOLVED: To provide an electromagnetic proportional valve in which side force is suppressed by constituting a magnetic gap without bringing an outer periphery of a plunger and an inner periphery of a yoke into direct contact by molding a resin sliding part of the plunger in a circumferential direction of the inner circumference of the yoke.SOLUTION: A recessed groove formed on a yoke 15 engages with a large diameter part of a movable core 16. The core, the yoke 15, and a core pin are attached to the mold and are insert molded. In this case, a resin sliding part is formed between the recessed groove and a groove formed on the outer circumference of the core pin, and a magnetic gap is formed between the inner circumference of the yoke 15 and a large diameter part of the movable core 16. |
