Abstract

A solenoid valve (1) comprises a fixed core (10), a bottomed tube (20) formed of a non-magnetic material and having a bottom (21), a movable core (30) slidably received within the bottomed tube (20) and opposed to the fixed core (10) with a gap therebetween, and a solenoid (60) for causing the movable core (30) to operate. The solenoid valve (1) also comprises a protruding portion (25,25') which is formed on the bottom (21) of the bottomed tube (20) and which protrudes in a direction of sliding of the movable core (30). The protruding portion (25,25') may comprise a plurality of convex-shaped protruding portions (25), a ridge-shaped protruding portion (25,25') extending along a whole circumference of the bottom (21) of the tube (20) or a plurality of ridge-shaped protruding portions (25,25') formed at circumferential equal intervals along a circumference of the tube bottom (21). The or each protruding portion (25,25') has a predetermined height.
