Claims

[Scope of utility model registration request]

It has a coil, a fixed body that holds the coil and magnetizes when a current is passed through the coil, and a movable body that is attracted to the fixed body, and mainly the fixed body and the movable body are relative to each other in the direction of movement. In a solenoid whose attractive force is determined by the distance between the surfaces of a ferromagnetic material, the solenoid has at least two pairs of surfaces with different distances between the surfaces, and at least one surface of the pair of surfaces with a small distance between the surfaces is directed in the movable direction. A solenoid characterized by being provided with elastic support means.
