PURPOSE:To absorb a shock and thereby facilitate stroke adjustment of a solenoid by connecting a lever shaft with a plunger of the solenoid using a springy connecting member. CONSTITUTION:A plunger 21 of a solenoid and a lever shaft 22 are connected with a plate-like connecting member 23, and the connecting member 23 has springiness because of its reversed U bend. The plunger 21 is energized by a return spring 24. Due to the flexibility of a distance between the plunger 21 and the lever shaft 22, the plunger 21 moves back and forth even after a valve of the lever shaft 22 contacts a valve seat under pressure. Consequently, the rocking width of the former is reduced to the return trip distance of the latter. In addition, the reaction of the lever shaft 22 is absorbed, and the spring force of the connecting member 23 is freely set by changing the width or shape of a reversed U part 23a. |
