PURPOSE:To obtain a strong attracting force by a fixed core by inserting a fixed core into an armature guide and joining the rear edge of the core to the rear part of a yoke surrounding a coil and arranging an armature in front of the fixed core. CONSTITUTION:A fixed core 3 is inserted into an armature guide 2, and the rear edge part of the core 3 is joined with the rear part 6a of a yoke 6 surrounding a solenoid coil 5 through a hole 4 formed onto the rear edge surface 2a of the guide 2. Further, an armature 7 is arranged in front of the fixed core 3. With such constitution, a strong attractive force by the fixed core can be obtained.
