Claim 0:
1. A solenoid valve, in which a rod is moved by a plunger that approaches and recedes from a stator by electromagnetic force, causing a valve body that opens and closes a valve to move reciprocally, wherein
a first space and a second space are formed at respective sides of the plunger in a movement direction of the plunger, the first space being positioned on a side of the valve body,
a through-hole is formed in the plunger so as to be concentric with a center axis,
the rod is arranged in the first space,
a communication passage is formed between an inner surface of the plunger and an outer surface of the rod and communicates with the first space and the second space,
the rod has a first part, a second part and a third part which are axially arranged from a side of the valve body toward a side of the plunger,
an outer peripheral surface of the first part is a circular surface extending over the entire circumference thereof,
an outer peripheral surface of the second part has at least an arc surface and a cutout surface,
an outer peripheral surface of the third part has at least an arc surface and a cutout surface,
the arc surface of the second part is flush with the circular surface of the first part,
the arc surface of the third part is formed on an inner diameter side with respect to the arc surface of the second part, and
the cutout surface of the second part and the cutout surface of the third part are flush with each other so as to collectively form one flat surface.
