成ることを特徴とするソレノイド。[Scope of Claim for Utility Model Registration] A movable member made of a magnetic material is inserted into the inner periphery of a cylindrical solenoid body so as to be able to move back and forth, and a fixing member made of a magnetic material is attached to one end of the solenoid body to magnetically attract the movable member. A cylinder made of a magnetic material is provided on the other end side of the solenoid main body so as to be separated from the fixed member by a predetermined distance, and the movable member is attached to the inside of the cylinder via a bearing member made of a non-magnetic material. In the solenoid, the movable member is magnetically attracted into a recess provided in the end face of the fixed member by slidingly guiding the solenoid body and energizing the solenoid main body, wherein one end of the non-magnetic bearing member is attached to the end face of the fixed member. What is claimed is: 1. A solenoid comprising: a solenoid press-fitted into a recess; and a magnetic fluid sealed in a gap between the inner periphery of the cylinder and the outer periphery of a bearing member.
