<P>PROBLEM TO BE SOLVED: To improve reliability of an electric throttle by preventing a trouble that an electric motor is obliquely attached by deviation of a wave washer. <P>SOLUTION: When incorporating a wave washer 6, each trough 6b of the wave washer 6 is led to the bottom of an engagement recessed part 7 by a tapered surface 7a. A washer position in an x-axis direction connecting two troughs 6b is regulated by a regulation wall 31. The two troughs 6b are engaged with the engagement recessed part 7 and a washer position in a y-axis direction (a direction perpendicular to the x-axis direction) is thereby regulated. In this way, a trouble that the wave washer 6 is incorporated in a deviated state is not caused, and a trouble that the wave washer 6 is deviated by disturbance with the electric motor unattached is not caused. As a result, a trouble that the electric motor is fastened to a throttle body 5 with the wave washer 6 deviated is not caused, and a trouble that the electric motor is obliquely attached can be prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
