Abstract
An electromagnetic valve includes a mover that is able to move in a predetermined direction. The mover includes a valve body part including a valve body base part and an annular elastic body. The valve body base part includes a large diameter part and a small diameter part connected via a step difference. The annular elastic body includes a first contact surface, a second contact surface in contact with a step difference surface in the step difference, and a sealing projecting part that is able to come into contact with a peripheral edge part of an opening part of a first flow path in the predetermined direction. The sealing projecting part surrounds the opening part when seen in the predetermined direction. The sealing projecting part, the second contact surface, and the step difference surface are at least partially superimposed on each other when seen in the predetermined direction.
