PROBLEM TO BE SOLVED: To attain an miniaturized outline by forming a choke coil so as to be disposable in parallel with the shaft direction of an armature with the choke coil protruding from both ends of a holder base, and be supported insulatably. SOLUTION: The first, second, and third choke coil retaining parts 1b, 1c, 1d are disposed on the outer periphery of the holder body 1a of a choke coil holder 1 so as to be lined in the circumferential direction of a central hole 1e, and the first guide 1b1 insulating the first choke coil 21 is formed on the first choke coil retaining part 1b. Guides 1c1, 1d1 insulating the second and third choke coils 22, 23 are formed on the second and third choke coil retaining parts 1c, 1d similarly. The choke coil is disposed with a choke coil holder so as to be parallel with the shaft direction of an armature with the choke coils protruding from both surfaces of a holder base for insulation. Therefore, the choke coil is not disposed on the holder base. It is thus possible to attain an miniaturized outline. |
