  • the resin case 3 may be deformed by heat generated at an engine.
  • the connector housing 33 may noticeably warp because the connector housing 33 extends from the solenoid housing 32 in an overhanging manner.
  • the case 3 may be deformed such that the connector housing 33 turns around an axis D of the connection portion 34 with respect to the solenoid housing 32 . Accordingly, a solder bonding portion 7 between the connector terminal 6 and the board 5 may be displaced in an F direction.
  • a component in an x direction of the displacement in the F direction is restricted by the board-holding unit 37 provided at the connection portion 34 .
  • Another component in a y direction of the displacement causes a frictional resistance between the board-holding unit 37 provided at the connection portion 34 and the board 5 .
  • stresses are generated at the solder bonding portion 7 in both the x and y directions, thereby making solder cracking more likely to occur.

  • the bonding portion Since a bonding portion between the connector terminal and the board is located near the connector side board-holding unit, the bonding portion is displaced with the connector side board-holding unit when the case is deformed by a heat load. Therefore, no relative displacement is generated in this occasion between the bonding portion and the connector side board-holding unit. Therefore, a resistance against the motion of the bonding portion during the deformation of the case can be reduced, and a stress generated at the bonding portion can be reduced.
  • a part of the solenoid side board-holding unit to be inserted and fitted to a corresponding one of the mounting holes may be elastically deformable toward the center of the mounting hole.
  • the board When the case is deformed by a heat load, the board is biased to rotate around the solenoid side board-holding unit, which serves as a fulcrum.
  • the above configuration makes the rotation of the board easier, since the part of the solenoid side board-holding unit to be inserted and fitted to the mounting hole may be elastically deformable toward the center of the mounting hole. Accordingly, the stress generated at the board and the bonding portion can be reduced.
  • the outer periphery of the solenoid side board-holding unit can be firmly attached to the periphery of the solenoid side mounting hole easily. As a result, positioning of the board in a direction parallel to the board can be facilitated when the board is assembled to the case.
  • the solenoid side board-holding unit may be divided into a plurality of pieces by a slit extending orthogonally to the board.
  • the board can easily rotate along with the thermal deformation of the case since the elastic deformation of the solenoid side board-holding unit is easily achieved. Therefore, the resistance force against the motion of the bonding portion during the deformation of the case can be further reduced, and the stress generated at the board and the bonding portion can be further reduced.
  • the solenoid housing, the connection portion, and the connector housing may be aligned in a reference direction.
  • the solenoid side board-holding unit may be disposed at a position in the solenoid housing wherein the position is farther from the connector housing than the center of the solenoid housing in the reference direction is.
  • the distance between the connector side board-holding unit and the solenoid board holing unit becomes large, that is, the radius of the rotation of the board during the case deformation becomes large. Therefore, the angle of the rotation of the board can be reduced, and accordingly the resistance force against the motion of the bonding portion during the deformation is further reduced. As a result, the stress generated at the bonding portion is further reduced.
  • a mounting-hole distance may be smaller than a holding-unit distance with the following four definitions.
  • the board-holding units are partially press-fitted to the mounting holes. Therefore, the board is reliably fixed to the case when the board-holding units are inserted and fitted to the mounting holes.
