<P>PROBLEM TO BE SOLVED: To reduce labor required for electrical connection work, and to facilitate alignment of a sensor. <P>SOLUTION: An actuator 1 for a valve includes a lower housing (housing body) 2B and an upper housing (cover) 2A, with a motor 3 and a gear train 4 being attached to the lower housing 2B, so that rotation of the motor 3 is transmitted to the gear train 4 for rotating the gear train 4. It includes a printed board 5 to which a connection terminal 3a that protrudes from the motor 3 is connected, and a sensor 7 for detecting a rotational condition of a sixth gear 16. The sensor 7 is mounted on the printed board 5, and the printed board 5 is attached to the lower housing 2B such that it is orthogonal to the connection terminal 3a. <P>COPYRIGHT: (C)2011,JPO&INPIT |
