<p>PROBLEM TO BE SOLVED: To provide a solenoid in which the number of parts is reduced, the number of works processes is reduced, and quality thereof is stabilized. SOLUTION: This solenoid 1A comprises a cylindrical bobbin 2 of nonmagnetic material, a coil 3 wound around the outer periphery of the bobbin 2, a plunger 4 of magnetic material which is held in a cylinder 20 of the bobbin 2 while relative displacement in an axial direction P is allowed and further has a driving part 4d held on its one end directly or indirectly with a connecting part 4c in between, a yoke 5A which is fixed to the bobbin 2 and, together with the plunger 4, forms a magnetic circuit. The yoke 5A comprises a guide part 52a which is integrated with the yoke 5A to guide the driving part 4d while allowing relative displacement thereof.</p> |
