Abstract
A solenoid includes a coil portion, a yoke having a side portion and a bottom portion, a plunger, and a stator core. The stator core has a magnetic attraction core and a sliding core which has a tubular core portion and a first magnetic flux transfer portion formed from the tubular core portion and the core end portion toward an outside in a radial direction to transfer magnetic flux between the yoke and the core portion. A breathing groove communicating an inside and an outside of the first magnetic flux transfer portion in the radial direction is formed on at least one of a first facing surface facing the bottom portion in a first magnetic flux transfer portion and a second facing surface facing the first magnetic flux transfer portion at the bottom portion so as to be positioned in a vertical direction when the solenoid is assembled.
