In addition, the inner face 20q that the footpath of bottom surface sections 20c makes progress also is formed the curved surface shape, thereby can connect with the outer peripheral face of the 4b of cylinder section of housing 4.Namely, shown in Fig. 8 (A), (C), being shaped as of inner face 20q when observing from above-below direction: the center of curvature of inner face 20q is roughly consistent with the center of curvature of the outer peripheral face of the 4b of cylinder section, and, about equally roughly circular-arc of the radius of curvature of the outer peripheral face of the radius of curvature of inner face 20q and the 4b of cylinder section.The inner face 20q of the bottom surface sections 20c of the manner is the second inner face.
Be formed with two holding section 20r on the bottom surface sections 20c, these two holding section 20r are first holding sections that engage with the notch 4c of housing 4.Two holding section 20r are respectively formed at the both ends on the circumferencial direction of inner face 20q.In addition, holding section 20r is formed towards radially inner side outstanding a little, and the leading section of holding section 20r (radially inner side end) 20s is formed towards the downside slight curvature.Holding section 20r engages with the bight 4d (with reference to Fig. 5) of the lower edge of notch 4c.
The lateral surface 20t that the footpath of the leading section 20s of holding section 20r makes progress is formed the curved surface shape, thereby can connect with the inner peripheral surface of the 4b of cylinder section of housing 4.Namely, shown in Fig. 8 (C), being shaped as of lateral surface 20t when observing from above-below direction: the center of curvature of lateral surface 20t is roughly consistent with the center of curvature of the inner peripheral surface of the 4b of cylinder section, and, about equally roughly circular-arc of the radius of curvature of the inner peripheral surface of the radius of curvature of lateral surface 20t and the 4b of cylinder section.In addition, shown in Fig. 8 (A), (C), the medial surface 20u that the footpath of the leading section 20s of holding section 20r makes progress also is formed the curved surface shape.
In the manner, by holding section 20f is fastened among the through hole 17e of end plate 17, and holding section 20r is fastened on the bight 4d of lower edge of notch 4c, thereby cover 20 is installed on the housing 4.As mentioned above, the notch 4c of cover 20 covered substrates 18 and portion of terminal 28 and covering shell 4.
(configuration of lead-in wire)
As mentioned above, lead-in wire 19 is fixed on the upper end side of substrate 18 by soldering, and is drawn from the radially inner side of substrate 18.As shown in Figure 9, from the derivative lead-in wire 19 of the radially inner side of substrate 18, from being drawn towards upside along partition board portion 15c between the partition board portion 15c of support plate 15 and the substrate 18 and between the protuberance 20e of partition board portion 15c and cover 20.
In addition, the lead-in wire 19 of being drawn towards upside is after radial outside is bent into approximate right angle, passes through from the notch 20d of cover 20, thereby drawn towards radial outside.That is, the lead-in wire 19 of being drawn towards upside is drawn towards radial outside from notch 20d after radial outside is bent into approximate right angle.At this moment, lead-in wire 19 passes through between the lower surface of the guide portion 17d of the upper surface of the protuberance 20e of cover 20 and end plate 17, thereby is highlighted the 20e of section and guide portion 17d guides radial outside into.
In addition, the distance between the lower surface of the upper surface of protuberance 20e and guide portion 17d is greater than the external diameter of lead-in wire 19, and as shown in Figure 9, lead-in wire 19 is not highlighted the upper surface of the 20e of section and the lower surface of guide portion 17d is clamped.Therefore, when usually using, can not act on the lead-in wire 19 from the power of protuberance 20e with from the power of guide portion 17d.
In addition, the medial extremity 20g beeline diametrically of partition board portion 15c and protuberance 20e is greater than the external diameter of lead-in wire 19, and as shown in Figure 9, lead-in wire 19 is not clamped by the medial extremity 20g of partition board portion 15c and protuberance 20e.Therefore, when usually using, can not act on the lead-in wire 19 from the power of partition board portion 15c with from the power of the medial extremity 20g of protuberance 20e.
(assembling sequence of motor)
In the motor 1 of above-mentioned formation, at first, assemble rotor 8 and assembling stator 11, and rotor 8 and stator 11 are configured to the inside of housing 4.Then, the support plate 15 that is fixed with bolster 14 is configured in the upside of stator 11, and each gear that will consist of gear train 13 is installed on the bolster 14.Then, end plate 17 is fixed on the upper end of housing 4.Under this state, gear train 13 is covered fully by the partition board portion 15c of the 4b of cylinder section of housing 4, support plate 15 and end plate 17.
Then, make wiring pin 27 insert the logical substrate 18 that is fixed with lead-in wire 19, and substrate 18 is remained on the substrate maintaining part 15b.Be that wiring pin 27 is inserted under the state of logical substrate 18 specifically, the outside of substrate 18 from circumferencial direction embedded the maintenance groove 15h of arm 15f.Since support plate 15 thereby is formed by resin can strain, therefore, in the time of in the maintenance groove 15h that substrate 18 is embedded arm 15f, two arm 15f are immediate recovery original state extremely after temporarily opening towards the direction that is separated from each other.
Under this state, with substrate 18 solderings on wiring pin 27.Then, cover 20 is installed on the housing 4.At this moment, will go between 19 between the partition board portion 15c of support plate 15 and the substrate 18 and between the protuberance 20e of partition board portion 15c and cover 20 along partition board portion 15c after upside is drawn, to go between 19 is bent into approximate right angle towards radial outside, and along the guide portion 17d of end plate 17 and the 19 notch 20d from cover 20 that will go between draw towards radial outside.
(the main effect of the manner)
As mentioned above, in the manner, lead-in wire 19 be drawn towards upside and by bending after, the notch 20d along the guide portion 17d of end plate 17 from cover 20 draws towards radial outside.Therefore, in the manner, when lead-in wire 19 by being pulled, lead-in wire 19 comes in contact with end plate 17 or cover 20.Specifically, when lead-in wire 19 was pulled, lead-in wire 19 came in contact with the lower surface of guide portion 17d or the medial extremity 20g of protuberance 20e, limits thus the movement of lead-in wire 19.Therefore, in the manner, the pulling force when lead-in wire 19 is pulled is difficult to directly act on the coupling part of substrate 18 and lead-in wire 19.Consequently, in the manner, can suppress to go between 19 comes off from substrate 18 when being pulled.
In addition, in the manner, the protuberance 20e of cover 20 is formed the upper surface 18c of complete covered substrate 18 diametrically, and, as mentioned above, suppose to be maintained at substrate 18 on substrate maintaining part 15b and the portion of terminal 28 when upside is moved, the upper surface 18c of substrate 18 can connect with the lower surface 20h of protuberance 20e.Therefore, in the manner, the pulling force in the time of can utilizing the lower surface 20h of protuberance 20e to bear lead-in wire 19 to be pulled, thus can effectively suppress to go between 19 comes off from substrate 18 when being pulled.
In the manner, by holding section 20f is fastened among the through hole 17e of end plate 17, and holding section 20r is fastened on the bight 4d of lower edge of notch 4c, cover 20 is installed on the housing 4.Therefore, in the manner, can utilize holding section 20f and holding section 20r reliably cover 20 to be installed on housing 4 and the end plate 17.In addition, in the manner, by the fastening state of releasing through hole 17e and holding section 20f, and the fastening state of releasing bight 4d and holding section 20r, thereby can easily cover 20 be removed from housing 4.
