<p>PURPOSE:To connect an armature surely attracted to a rotor by fixing a clearance among the armature, rotor and an electromagnetic coil. CONSTITUTION:A shaft 2 is provided in a fixed position relating to a body 1 by a collar 10 and a coil spring 5. A hub 11 is fixed to this shaft 2, and further a rotor 14 is provided turnably further with shaft direction movement restricted relating to the shaft 2. In this way, a predetermined clearance is always held between an armature 13 mounted through a leaf spring 12 to the hub 11 and the rotor 14. A predetermined clearance is always held also between an electromagnetic coil 151 mounted to the body 1 and the rotor 14. Since the clearance can be always fixed, the armature 13 can be surely attracted to the rotor 14 when the electromagnetic coil 151 is placed in an electrification condition, and a turning amount of a motor 17 can be surely transmitted to a valve 3.</p> |
