PROBLEM TO BE SOLVED: To provide a yoke portion which improves the heat dissipation of a coil by forming a space on the circumferential surface of a coil case housing the coil. SOLUTION: The yoke portion 37 is laterally provided with belt-shaped coil yokes 36d at four positions at equal intervals on the outer circumferential surface of disk-shaped coil yokes 36a to 36c. The coil yokes 36a and 36b are provided with T-shaped projections 46 at four positions at radially equal intervals on the outer circumferential surface of a disk 45 and are formed in its center with a hole into which a solenoid guide is inserted. The coil yoke 36c is formed with a hole on a disk 48. The coil yokes 36d are formed with depressed grooves at both ends of the belt-shaped plate member. The depressed grooves are configured to engage with the projections 46 of the coil yokes 36a and 36b. COPYRIGHT: (C)2011,JPO&INPIT
