Claims

[Scope of utility model registration request]

A valve seat has a nipple and a valve seat that form a flow path, and a sliding portion formed in the valve seat is provided so as to be able to slide freely and come into contact with the valve seat. A movable valve body that opens and closes a passage, a bobbin connected to the valve seat and around which a coil is wound, a nipple disposed within the bobbin and forming a flow passage, and working together with the movable valve body. a fixed iron core having a valve seat that opens and closes a flow path, and a spring that is provided between the fixed iron core and the movable valve body and biases the movable valve body in the axial direction of the fixed iron core. A stepped portion is formed on the outer periphery of the tip, and the tip of the fixed core is joined to the inner wall surface of the opening of the sliding portion, and a gap is formed between the stepped portion and the end surface of the opening. A solenoid valve characterized by:
