Abstract

A stationary annular abutting member 14E is provided with a first projecting section that operates as part of a ratchet mechanism. A rotational flange section is provided with a second projecting section that operates as part of the ratchet mechanism. The first projecting section projects in the direction from the ON position toward the OFF position of a plunger of a solenoid. The second projecting section projects in the direction from the OFF position toward the ON position of the plunger. When a driven rotor starts rotating and comes to a rotary position slightly short of the rotary position of about ¾ of a full turn in the ON state of the solenoid, the projecting end of the first projecting section and that of the second projecting section are located opposite to each other and the second projecting section rides on the first projecting section.
