  • the space between the housing 35 and the housing space 44 is sealed by the seal member 97, and the motor 36, the speed reduction unit 37, and the rotation angle sensor 39 in the housing 35 are protected from the external environment by ensuring waterproofness and dustproofness. , Robustness can be improved.
  • the seal member 97 in the annular gap between the inner wall of the connector insertion hole 76 and the fitting portion 85, space saving can be achieved.
  • the connector 83 is centered in the connector insertion hole 76 by the tension force of the seal member 97, and the positioning accuracy is improved.
  • the wire holding member 71 is provided so as to overlap with the bearing 49 provided between one end of the output shaft 38 and the housing 35.
  • the cross-sectional shape of the connector insertion hole 102 of the second housing portion 101 and the fitting portion 105 of the connector portion 104 of the wiring holding member 103 fitted thereto are It is oval.
  • the rotation of the wiring holding member 103 can be restricted by the fitting portion 105.
  • a seal member 115 is provided in a gap between the two flat surfaces 113 and 114 of the second housing portion 111 and the wiring holding member 112.
  • the annular groove is not formed in the fitting portion 117 of the connector portion 116 of the wiring holding member 112, and the annular groove 119 is formed in the main body portion 118.
  • the seal member 115 is provided so as to surround the connector portion 116 as viewed in the insertion direction of the fitting portion 117 into the connector insertion hole 76.
  • the seal member 115 is compressed by being sandwiched between the second housing portion 111 and the wiring holding member 112.
  • the compression direction of the seal member 115 is the same as the insertion direction of the connector portion 116, and is the direction in which the second housing portion 111 and the wiring holding member 112 face each other.
  • the seal between the second housing portion and the wire holding member may be a face seal.
  • the connector insertion hole may be formed in the first housing portion.
  • the wire holding member may be fixed to the first housing portion.
  • the second housing portion is not limited to the aluminum alloy, and may be made of, for example, another metal such as a magnesium alloy or a high strength material such as an engineering plastic. Nevertheless, the strength of the second housing part can be guaranteed against relatively large loads due to exhaust pulsations.
  • the cross-sectional shapes of the connector portion and the connector insertion hole are not limited to rectangular and elliptical, and may be other non-circular shapes. In short, any shape may be used as long as the rotation of the connector portion relative to the connector insertion hole is restricted.
  • the cross-sectional shape of the connector portion may be substantially the same from the root portion (that is, the fitting portion) to the tip end portion.
  • a positioning protrusion may be provided on the housing and a positioning hole may be provided on the wire holding member.
  • the wire holding member is not limited to the screw, but may be fixed to the housing by other methods such as heat caulking, rivets and the like.
  • an annular groove provided with a sealing member may be provided in either the housing or the wire holding member.
