<p>PROBLEM TO BE SOLVED: To reduce the cost of a solenoid by reducing the number of parts by integrally molding a pipe section and a case section. SOLUTION: A solenoid 5 is provided with a resin case 51. The case 51 is composed of an integrally molded body, in which a case section 51b is arranged around a bottomed pipe section 51a, and the pipe section 51a houses a movable core 52 in a state such that the core 52 is slidable in the axial direction. The case section 51b houses a solenoid coil 56 wound around a bobbin 55, a hollow cylindrical case 58 which is arranged on the outer peripheral side of the coil 56 and made of a magnetic material, and doughnut-shaped platy yokes 54 and 57 arranged on the both end face sides of the case 58.</p> |
