To obtain, as one example, an electromagnetic valve which can accurately and easily control a position of a movable member.SOLUTION: An electromagnetic valve according to the present embodiment comprises, as one example, a box body in which a communication hole for making a first chamber and a second chamber communicate with each other, and a flow passage which is opened in the first chamber in a position separated from the communication hole are formed, a movable member extending between a first end part and a second end part while passing through the communication hole, and movable between a closed position at which the first end part blocks the flow passage, and an open position at which the end part releases the flow passage, a plunger located in the second chamber, and an elastic body for pressing the movable member toward the open position. The movable member has a first portion which is guided by an inner face of the communication hole, and a second portion located between the first portion and the first end part, and thinner than the first portion, and an end of the second portion is located in the communication hole in the open position, and located in the first chamber in the closed position.SELECTED DRAWING: Figure 2
【課題】一例として、可動部材の位置を正確に制御しやすい電磁弁を得る。【解決手段】実施形態に係る電磁弁は、一例として、第1の部屋と第2の部屋とを連通する連通孔と、前記連通孔から離間した位置で前記第1の部屋に開口する流路と、が設けられた筐体と、前記連通孔を通って第1の端部と第2の端部との間で延び、前記第1の端部が前記流路を塞ぐ閉位置と、前記流路を開放する開位置と、の間で移動可能な可動部材と、前記第2の部屋に位置するプランジャと、前記可動部材を前記開位置に向かって押す弾性体と、を備え、前記可動部材は、前記連通孔の内面によってガイドされる第1の部分と、前記第1の部分と前記第1の端部との間に位置するとともに前記第1の部分よりも細い第2の部分と、を有し、前記第2の部分の端は、前記開位置において前記連通孔の内部に位置し、前記閉位置において前記第1の部屋の内部に位置する。【選択図】図2
