Electromagnetic valve device and manufacturing method thereof

An electromagnetic valve device, comprising:

• a moving member;
• a valve member reciprocating together with said moving member, for controlling a flow rate of a fluid passing through a fluid path;
• an energizing means for energizing said moving member in a first reciprocating direction;
• a coil portion for generating a magnetic force to attract said moving member in a second reciprocating direction;
• a stator for forming a magnetic circuit with said moving member, the stator having a tube portion covering an outer periphery of said moving member and a suction portion forming a gap between said tube portion and itself in the first and second reciprocating directions of said moving member, the suction member attracting said moving member in the second reciprocating direction;
• and
• a non-magnetic member provided at an inner circumference of said tube portion, for movably supporting said moving member in a reciprocating manner, the non-magnetic member covering an end of said moving member in one of the reciprocating directions, the non-magnetic member extending to said suction portion to cover an outer periphery of said suction portion, wherein
• said moving member has a hard portion with a hardness close to a hardness of said non-magnetic member at a sliding part against said non-magnetic member.
