PROBLEM TO BE SOLVED: To suppress impact noise and vibration by absorbing an impact energy generated by the collision of a plunger 5 with a core 10. SOLUTION: A yoke 4 is formed in a cylindrical shape having a bottom surface, and a recessed part 4a is formed in the bottom surface front side of the yoke 4 by recessing inward the bottom surface center part thereof. An elastic member 11 (for example, rubber) is fitted to the recessed part 4a, The elastic member 11 is formed almost in same size as that of the recessed part 4a, and forms almost the same surface as the front surface of the yoke 4 without being projected largely from the front surface of the yoke 4 to the outside. Thus, since the impact energy generated when the plunger 5 is sucked and collides with the core 10 can be absorbed by the elastic member 11, impact noise is relieved and changed from normal high metallic noise to low noise, and the noise leaking to the outside through the yoke 4 can be reduced.
