Patent ID: 7554231

Claim:
A motor actuator comprising: a motor; a cam which is driven by the motor; a first switch contact piece and a second switch contact piece whose one end portion contacts with the cam to perform a switch operation; an output member which is driven by the motor; a housing case which accommodates at least the cam, the first switch contact piece and the second switch contact piece in an inside of the housing case; and connection terminals attached to the housing case for connecting an external power supply to the motor; wherein the cam is formed with a step part for operating the first switch contact piece and the second switch contact piece to indicate a predetermined position of the output member; wherein the first switch contact piece and the second switch contact piece are structured as a position sensor for detecting a predetermined position of the output member; wherein the connection terminals comprises: a first switch terminal which is formed in an other end portion of the first switch contact piece; a second switch terminal which is formed in an other end portion of the second switch contact piece; a first motor terminal which is connected to one end of the motor; and a second motor terminal which is connected to an other end of the motor; wherein the housing case is formed at fixing portions for the connection terminal with at least three cut-out portions with a predetermined interval in a contacting or separating direction of the first and the second switch contact pieces so that the first switch terminal, the first motor terminal and the second switch terminal are disposed in this order; and wherein an external connecting terminal part of the first motor terminal is protruded outside of the housing case through one of the cut-out portions such that the external connection terminal part of the first motor terminal is disposed between an external connection terminal part of the first switch terminal and an external connection terminal part of the second switch terminal both of which are protruded outside of the housing case.
