Abstract: Water introduced to inside a cover via a space between a cylindrical portion of a first tube of the cover and a solenoid case is discharged out of the cover via a space formed between the cover and an upper-side end portion of a valve case and a plurality of passages formed between a lower-side end portion of a second tube and an upper end portion of a base portion of the valve case, and therefore an uncoated portion inside the cover can be prevented from being rusted.

Abstract: A solenoid includes a coil bobbin, a coil, a terminal, a housing, an armature, an actuation pin, and the like. The coil bobbin includes a tubular portion, and a first flange portion formed on one end of the tubular portion and extending radially to outside the tubular portion. The coil is wound around the coil bobbin. The terminal connects a terminal conductor portion of the coil and a cable. The terminal includes a joint portion that joins the terminal conductor portion of the coil. The joint portion extends in a direction along one end surface of the first flange portion.
