These two side surfaces (fixed side positioning portions 418A, 418B) are both surfaces facing the + Z direction. The fixed-side positioning portions 418A and 418B function as positioning portions that contact the fixed portion 83 from the −Z direction side to position the fixed portion 83, as will be described later.

  Next, the shape on the holder 40 side to which the fixing portions 84 and 85 are fixed is as follows. A groove portion 444 is formed on the inner side surface 441 of the wall portion 44 (+ Y). The groove portion 444 is located at the center in the width direction of the inner side surface 441 and extends in the Z-axis direction. A central groove 445 that is recessed deeper than the groove 444 is formed at the center in the width direction of the groove 444.

Therefore, the fixed side positioning portion 449A and the fixed side positioning portion 449B are formed on the inner side surface 441 of the wall portion 44 (+ X), similarly to the wall portion 44 (+ Y).

  FIG. 9 is a perspective view of the flexible wiring board 80 as seen from the image side. The flexible wiring board 80 is a member obtained by joining rigid reinforcing plates 92, 93, 94, and 95 to a flexible board 91 on which wiring patterns such as power supply line patterns and signal line patterns and lands 813 are formed. is there. The frame portion 81 of the flexible wiring substrate 80 is a portion where a reinforcing plate 92 is joined to the flexible substrate 91. The fixing portions 83, 84, and 85 are portions where the reinforcing plates 93, 94, and 95 are joined to the flexible substrate 91, respectively. The reinforcing plates 92, 93, 94, and 95 are surface-bonded to the flexible substrate 91 with an adhesive or the like.

  Sensors 101 and 103 are mounted on the flexible substrate 91. The sensor 101 is provided on the fixed portion 84, and the sensor 103 is provided on the fixed portion 85. The thermistor 102 is mounted on the fixed portion 84. In the fixing portions 84 and 85, the flexible substrate 91 is located on the outer peripheral side of the reinforcing plates 94 and 95.

Moreover, the sensor 103 is arrange | positioned at the through-hole 443 formed in the wall part 44 (+ X). As the sensors 101 and 103, various types of detection methods can be used. In this embodiment, a magnetic sensor is used. Therefore, since the magnetic sensor faces the magnet 52 through the through hole 443, the magnetic field by the magnet 52 can be detected.

  The frame portion 81 is joined to the substrate support portion 411 of the holder 40 via the reinforcing plate 92. A groove for arranging an adhesive is formed in the substrate support portion 411. Adhesive is applied to the groove and the reinforcing plate 92 is brought into contact with the substrate support portion 411, whereby the frame portion 81 is bonded and fixed to the substrate support portion 411. When the reinforcing plate 92 is directed toward the substrate support portion 411, the flexible substrate 91 faces in the + Z direction, so that the land 813 and the solder bump 814 are exposed.

  The fixing portion 83 is connected to the inner peripheral edge of the frame portion 81 through the bent portion 96 of the flexible substrate 91. The bent portion 96 is bent in the −Z direction from the inner peripheral edge of the frame portion 81 and then bent in the −Z direction after being bent toward the outer peripheral side and connected to the fixed portion 83. In addition, bent portions 97 of the flexible substrate 91 are provided at the ends of the fixed portions 84 and 85 in the −Z direction, respectively. The fixing portions 84 and 85 are connected to the outer peripheral edge of the frame portion 81 via the bent portion 97.

  The bent portions 96 and 97 of the flexible substrate 91 are elastically deformable portions and have an elastic force for returning to a predetermined shape. Specifically, the bent portion 96 tends to return to a linear shape from the bent shape, and hence the fixing portion 83 is urged in the −Z direction by its elastic force. Further, the bent portion 97 tries to return from the bent shape to a straight shape, but since the deformation toward the outer peripheral side is restricted by the wall portion 44, the fixed portions 84 and 85 are urged in the + Z direction. Thus, when the direction in which the fixing portion 83 is urged by the elastic force of the bent portion 96 to return to a predetermined shape is the first direction F1 (see FIG. 9), the first direction F1 is the −Z direction. . Further, when the direction in which the fixing portions 84 and 85 are urged by the elastic force of the bent portion 97 to return to a predetermined shape is the first direction F2 (see FIG. 9), the first direction F2 is the + Z direction.

  As shown in FIG. 7, the fixing portion 83 of the flexible wiring board 80 is fixed to a groove portion 413 formed on the inner peripheral surface of the frame portion 81.

That is, the bottom surface 415 is a substrate mounting surface to which the fixing portion 83 is fixed. The fixing portion 83 is disposed with the surface on which the flexible substrate 91 is disposed facing the groove portion 413, and is joined to the bottom surface 415 of the groove portion 413 through the flexible substrate 91.

  The fixing portions 84 and 85 are fixed to the groove portions 444 formed on the inner side surfaces 441 of the wall portions 44 (+ Y) and 44 (+ X), respectively. An adhesive is disposed in the central groove 445 formed in the groove portion 444. The fixing portions 84 and 85 are joined to the bottom surface 446 of the groove portion 444 through an adhesive layer. That is, the bottom surface 446 is a substrate mounting surface to which the fixing portions 84 and 85 are fixed. The fixing portions 84 and 85 are disposed with the surface on which the flexible substrate 91 is disposed facing the groove portion 444, and are joined to the bottom surface 446 of the groove portion 444 through the flexible substrate 91.

The reinforcing plate side positioning portions 842A and 842B are portions located at both ends in the width direction of the end surface of the reinforcing plate 94 in the + X direction. As a result, the movement of the fixed portion 84 in the + Z direction (biasing direction) is restricted by the fixed-side positioning portions 449A and 449B. Accordingly, the fixing portion 84 is positioned in the Z-axis direction.

  The positioning structure of the fixing portion 85 is the same as that of the fixing portion 84. That is, the fixing portion 84 is formed with reinforcing plate side convex portions 851A and 851B that fit into the concave portions 448A and 448B formed in the groove portion 444. Reinforcing plate side positioning portions 852A and 852B are provided on the outer peripheral surfaces of the reinforcing plate side convex portions 851A and 851B in the portion facing the + Z direction.
