As shown in Figure 4, be provided with at the lower surface of the outside part 61 of upside: the multiple grooves 611 radially extended; And for configuring the upper recess 612 of aftermentioned inner side part 71.Upper recess 612 is positioned at than the position of multiple groove 611 by radially inner side.Further, be provided with at the upper surface of the outside part 62 of downside: the multiple grooves 621 radially extended; And for configuring the lower concave part 622 of aftermentioned inner side part 72.Lower concave part 622 is positioned at than the position of multiple groove 621 by radially inner side.
Second maintaining part 242 is formed by the pair of inside part 71,72 configured up and down.Being positioned at least partially than the position of the first maintaining part 241 by the private side of motor chassis 23 of second maintaining part 242.Use at normal temperatures for solid but can because of motor chassis 23 shaping time heat and the thermoplastic resin that melts as the material of inner side part 71,72.Specifically, olefines adhering resin or polyesters PUR bonding agent can be used as the material of inner side part 71,72.As shown in Figure 4, the multiple grooves 711 radially extended are provided with at the lower surface of the inner side part 71 of upside.Further, the multiple grooves 721 radially extended are provided with at the upper surface of the inner side part 72 of downside.
When assembling conductor maintaining part 24, first, combination pair of inside part 71,72, forms the second maintaining part 242.Now, clamp leads 27 between the groove 711,721 of upper and lower both sides, and the upper surface of the lower surface of the inner side part 71 of upside and the inner side part 72 of downside contacts with each other.Then, combination pair of outside part 61,62, forms the first maintaining part 241.Now, clamp leads 27 between the groove 611,621 of upper and lower both sides, and between upper recess 612 and lower concave part 622, clamp the second maintaining part 242.Further, the upper surface of the lower surface of the outside part 61 of upside and the outside part 62 of downside contacts with each other.Thus, obtain the conductor maintaining part 24 of integration, become the state keeping lead-in wire 27 in this conductor maintaining part 24.
But the first maintaining part 241 also any one only in two outside parts 61,62 can have the groove that lead-in wire 27 keeps.Further, the second maintaining part 242 also any one only in two inner side parts 71,72 can have the groove that lead-in wire 27 keeps.
When motor chassis 23 is shaping, the conductor maintaining part 24 of assembling in above-mentioned steps, stator 21 and circuit board 22 are configured at the inside of mould.Then, by the cavity in this mould of the resin injection of flow regime.Then, by making resin at the inside solidification of mould, obtain motor chassis 23.

The temperature injecting the resin of the inside of mould is generally 90 DEG C to 130 DEG C.In the present embodiment, the fusing point forming the material of inner side part 71,72 is lower than the temperature of the resin of this flow regime.Therefore, when by the inside of resin injection mould, inner side part 71,72 melts because of the heat come from resin conduction.Consequently, inner side part 71,72 is fused to the parts of surrounding.Specifically, inner side part 71,72 be fused to contact with inner side part 71,72 outside part 61,62, go between 27 and motor chassis 23.Further, inner side part 71,72 also welding mutually each other.
Thus, if the second maintaining part 242 to be fused to the parts of surrounding, then the gap between the parts that contact with the second maintaining part 242 of the second maintaining part 242 is closed.Therefore, even if water droplet enters in motor chassis 23 from the first maintaining part 241 and the border of motor chassis 23 or the border of the first maintaining part 241 and lead-in wire 27, also these water droplets can be stopped in the second maintaining part 242.Therefore, it is possible to suppress water droplet to enter than the position of the second maintaining part 242 by the private side of motor chassis 23.
Particularly in the present embodiment, heat when utilizing motor chassis 23 shaping makes inner side part 71,72 melt.Therefore, except the molding procedure of motor chassis 23 need not implement the operation heating inner side part 71,72 in addition.Therefore, it is possible to do not increase process number and carry out inner side part 71,72 welding.
In addition, in the present embodiment, the fusing point forming the material of pair of outside part 61,62 is higher than the temperature of the resin of above-mentioned flow regime.Therefore, even if when motor chassis 23 is shaping by the inside of resin injection mould, outside part 61,62 also can not melt because of the heat from this resin.Therefore, it is possible to make the second maintaining part 242 melt while the distortion of suppression first maintaining part 241.
In the present embodiment, inner side part 71,72 and outside part 61,62, go between 27 and motor chassis 23 all weldings.Therefore, it is possible to roughly fully stop water droplet to enter position than the second maintaining part 242 side close to the inner portion.But, inner side part 71,72 also can with outside part 61,62, go between 27 and motor chassis 23 all weldings.If inner side part 71,72 and outside part 61,62, at least one welding of going between in 27 and motor chassis 23, just can obtain the effect preventing water droplet from entering partly in this weld portion.
But preferably inner side part 71,72 is leaning on the position of the private side of motor chassis 23 to be fused to lead-in wire 27 and motor chassis 23 both sides than the first maintaining part 241.Thus, even if water enters into the first maintaining part 241, water droplet enters private side path from the first maintaining part 241 also can be closed.Therefore, it is possible to suppress entering of water droplet further.
Further, as shown in Figures 2 to 4, the second maintaining part 242 of present embodiment has: the rectangular body 73 clamped by two outside parts 61,62; And be positioned at than the protuberance 74 of outside part 61,62 by the position of radially inner side.Protuberance 74 is given prominence to from rectangular body 73 towards radially inner side, and along expansion lower on the surface of the first maintaining part 241.If be formed as such shape, then the contact area of the second maintaining part 242 and the first maintaining part 241 and the contact area of the second maintaining part 242 and motor chassis 23 increase.Therefore, by the increase of labyrinth effect and welding area, can water droplet be suppressed further to enter.
Further, as shown in Figure 2, in the present embodiment, the both ends of the surface of the circumference of rectangular body 73 are exposed from the first maintaining part 241.These faces of exposing contact with motor chassis 23, and are fused to motor chassis 23.If make at least two faces beyond two faces contacted with outside part 61,62 of rectangular body 73 expose from the first maintaining part 241 like this, then the second maintaining part 242 increases with the welding area of motor chassis 23.Consequently, entering of water droplet can be suppressed further.
Further, in the present embodiment, be arranged at upside inner side part 71 multiple grooves 711 and be arranged at downside inner side part 72 multiple grooves 721 between configure many and go between 27.Further, go between the outer peripheral face of 27 and the bent plane-plane contact of each groove 711,721 of formation.Thus, the second maintaining part 242 increases with the welding area of lead-in wire 27.Therefore, it is possible to suppress water droplet to enter private side along lead-in wire 27 further.
Further, in the present embodiment, many lead-in wires 27 are kept by the inner side part 71,72 be connected as a single entity.Thus, the parts count of the second maintaining part 242 can be suppressed, and the operation of assembling the second maintaining part 242 becomes easy.Further, if parts count reduces, then the gap between part is also reduced, therefore, it is possible to suppress water droplet to enter further.
<2. the second execution mode >
Next, the second execution mode of the present utility model is described.Second execution mode only has the structure of conductor maintaining part 24A different from above-mentioned first execution mode.Therefore, the structure of conductor maintaining part 24A is only described below, omits the repeat specification to other parts.
Fig. 5 is the stereogram of conductor maintaining part 24A involved by the second execution mode and lead-in wire 27A.In the example of fig. 5, three lead-in wire 27A are kept by conductor maintaining part 24A.The conductor maintaining part 24A of present embodiment has: the first maintaining part 241A; And three the second maintaining part 242As identical with the quantity of lead-in wire 27A.
In the present embodiment, the shape of the second maintaining part 242A is cylindric.Three lead-in wire 27A are kept by the second maintaining part 242A by inserting respectively in the second maintaining part 242A.That is, the second maintaining part 242A covers a part for the outer peripheral face of each lead-in wire 27A.First maintaining part 241 is formed by pair of outside part 61A, the 62A configured up and down.Three lead-in wires 27A and three the second maintaining part 242A by hold remain on upside between outside part 61A and the outside part 62A of downside.
Thus, the second maintaining part 242A of present embodiment is not by keeping the 27A that goes between from upper and lower clamp leads 27A, but keeps by covering lead-in wire 27A the 27A that goes between.Further, in the present embodiment, the second maintaining part 242A is the parts of the split each other that number is corresponding to the number of lead-in wire 27A.Even such structure, as long as the parts the second maintaining part 242A being fused to surrounding, the gap between parts that the second maintaining part 242A contacts with the second maintaining part 242A just also can be closed.Therefore, it is possible to suppress water droplet to enter the inside of motor from the border of conductor maintaining part 24A and motor chassis 23A or the border of conductor maintaining part 24A and lead-in wire 27A.
