Claims

[Scope of utility model registration request]

(1) A cylindrical bobbin wound with an excitation coil, a fixed core fitted to one open end of the bobbin, a movable core inserted through the other open end of the bobbin and capable of moving toward and away from the fixed core; A frame having a U-shaped cross section and provided to surround an excitation coil, a magnetic body provided inside the open side of the frame and having a hollow portion coaxially with the hollow portion of the bobbin, and a magnetic body provided at the open end of the frame. and an annular permanent magnet interposed between a front frame having a hollow portion coaxially with the hollow portion of the bobbin and the magnetic front frame, and a ring-shaped permanent magnet that is interposed between the front frame and the magnetic front frame. The gap between the movable iron core is 0
1 The gap between the outer circumferential surface of the magnetic body and the inner circumferential surface of the frame is 02, the gap between the movable core and the fixed core in the open state is 03, and the gap between the circumferential surface of the hollow part of the magnetic body and the movable core is 03. When the gap is g, g < G,, g < G2
, G3:>Go, and G3>G2, each with a gap set therein.

(2) The solenoid according to claim 1, wherein the movable iron core has a small diameter portion that corresponds to the front frame.
