The lower end of each side piece 27a is bent outward at a right angle to form a projecting piece 27b, and the middle portion of each side piece 27a is bulged outward. . The distance A between the recesses 27c at the lower ends of the two side pieces 27a is set to be somewhat wider than the lateral width dimension of the insertion hole 25c of the spacer member 27, which allows the spacer member 27 to be inserted into the insertion hole 25c.
It is designed so that it can be elastically inserted into. In this case, the spacer member 27 includes the protruding pieces 27b between the land 28 at the tip of the mounting piece 24 and the side edge portion of the insertion hole 25c which is the vicinity of the land 28.

Next, a procedure for assembling the stator 16 will be described. First, cream solder is applied to each land 28 on the printed circuit board 14 and the attachment piece 24 by printing or the like. After that, the spacer member 27
Is grasped so as to sandwich the bulging portions of the both side piece portions 27a so as to narrow the space therebetween, and then both projecting piece portions 27b are pressed against the tip end portion (land 28) of the mounting piece portion 24. As a result, both projecting piece portions 27b press the bending piece portion 24 to bend the bending piece portion 24
The printed circuit board 1 is bent from 4a and passes through the insertion hole 25c.
When the force that clamps the spacer member 27 is loosened at the position projecting to the rear surface side of the spacer 4, the distance between the both side portions 27a of the spacer member 27 expands due to its elastic restoring force, and the two recessed portions 27c are inserted into the insertion holes 2c.
The spacer member 27 is temporarily fixed by being elastically engaged with the side edge portion of 5c. In this state, the spacer member 27 has the two protruding pieces 27b.
Is interposed (sandwiched) between the land 28 of the mounting piece portion 24 and the insertion hole 25c, and the bent state of the mounting piece portion 24 is kept constant by both projecting piece portions 27b. Then, the land with each cream solder on the printed circuit board 14 and the mounting piece 24 is attached.
The IC 29, the capacitor 30, the hall element 26, and other electrical components are placed on the 28, and the printed circuit board 14 is heated by passing through a reflow (not shown), which melts the cream solder to melt the IC 29, the capacitor. 30, the terminals of the Hall element 26, etc. are soldered to each land, and the two protruding pieces 27 of the spacer member 27
The b is soldered and fixed to the land 28 of the mounting piece 24. After that, the stator coil 13 and the bearing housing 12 are attached to the stator yoke 11, and then the printed circuit board 14 is attached from above, so that each end of the stator coil 13 is placed at a predetermined position on the printed circuit board 14. Stator 16 by joining
Is completed.

According to the above-described embodiment, the mounting piece portion 24 is integrally formed on the printed circuit board 14 so as to be inclined to the side opposite to the rotor magnet 22, and the spacing between the mounting piece portion 24 and the rotor magnet 22 is increased. Since the Hall element 26 is directly attached to the attachment piece portion 24 without a holder, the work of attaching the Hall element 26 can be simplified as compared with the conventional case in which the Hall element 26 is attached via the holder. It is also possible to solve the problem of deterioration of the position accuracy of the Hall element 26 due to the holder.

Moreover, since the spacer member 27 is interposed between the mounting piece portion 24 and the side edge portion of the insertion hole 25c of the printed circuit board 14, springback of the mounting piece portion 24 can be reliably prevented, and the mounting piece portion
The bending angle of 24 can be kept constant for a long period of time. Therefore, it is possible to reliably prevent a decrease in the gap between the Hall element 26 and the rotor magnet 13 due to aging, and in combination with omitting the conventional holder, it is possible to greatly improve the position accuracy of the Hall element 26. The rotation detection accuracy of the rotor 19 can be improved.

Further, in the above-mentioned embodiment, since the spacer member 27 is fixed to the mounting piece portion 24 by soldering, it is possible to reliably prevent the spacer member 27 from being displaced due to vibration during operation, which can contribute to the improvement of reliability. Of course, the spacer member 27
Can be fixed (soldered) simultaneously with the soldering of other electric components such as the Hall element 26, for example, by reflow soldering, and the spacer member 27 can be fixed without any trouble. Moreover, when reflow soldering is performed as in the above-described embodiment, the mounting piece 24
It is possible to slightly soften the bent portion 24a of the above and reduce the bending stress in that portion, and it is possible to prevent the mounting piece portion 24 from warping due to the bending stress.
