PROBLEM TO BE SOLVED: To provide an outer yoke capable of reducing magnetic resistance of a magnetic circuit formed around a coil in a linear solenoid in which a plunger is fitted to a center hole of a coil assembly formed by winding a coil, and the plunger is moved by conducting the coil. SOLUTION: The outer yoke 2 is formed by mounting a plurality of curved outer yoke pieces 10, 10 on an outer circumferential surface of the coil assembly 7 without a clearance. The outer yoke 2 is fixed by engaging and caulking recessed parts 11, and convex parts 12, formed on both sides of the respective outer yoke pieces 10. COPYRIGHT: (C)2011,JPO&INPIT |
