Even in a small motor in which a winding is wound around a coil bobbin, an example in which a lead wire is used as an electrical connection means with the outside is generally used. In the configuration in which the lead wire is integrally fixed to the motor body, various measures are accumulated because it is quite troublesome to secure the removal force for the lead wire used.

いのが実状であった。Japanese Utility Model Laid-Open Publication No. 64-16167 discloses an example in which a relay terminal is provided side by side to connect a winding end to a lead wire, and a lead bush formed integrally with a coil bobbin is provided with a groove. It is intended to secure the removal force by inserting a lead wire inside by crimping.
No. is a configuration in which the winding end and the lead wire are directly connected. A substantially L-shaped groove is formed in the lead bush, and the lead wire is inserted in the groove and is bent at the corner of the groove. The resistance is used as a means for securing the removal force. Further, JP-A-62-1
No. 69404 also has a structure in which the winding end is directly connected to the lead wire, but a relatively long circumferential groove is formed to make the lead wire crawl on the thick portion of the coil bobbin with a thick flange. Then, the lead wire is inserted and the friction with the wall surface of the groove is used as a means for securing the removal force. Each of these configurations utilizes the frictional resistance between the inner wall or corner of the groove formed in the lead bush and the surface of the lead wire. Generally, the structure of the lead bush is formed by molding an insulating resin member. In fact, it was not possible to ignore a decrease in the pulling force due to variations in the width.

なりつつある事等別の問題を派生させるに至っている。It is also well known that a terminal having a winding end internally connected is used as a lead end of a motor body, and a lead wire is used instead of directly fixing a lead wire and a connector is used as an external member. However, since the connection of the winding ends is intended for the fixed terminal, the connection work is easy and the lead wire is not fixed to the motor body, so the handleability is excellent, but the recent motor body The reduction in the absolute amount of the required cost has led to another problem, such as the fact that the cost of the combined connector is becoming unacceptable.

するようにする。FIG. 1 is a sectional view of an essential part of an example of a drawer structure according to the present invention. In this example, the stator 4 includes two sets of windings, and the windings 4 respectively wound on two coil bobbins 5-1.
The winding end 4-1 is wound around and connected to the root of a lead terminal 6 planted on the outer peripheral edge of the flange of the coil bobbin 5-1. The lead wires 3 are connected and fixed to the same lead terminal 6, respectively. A hinge 5-10 is provided on the outer peripheral edge of the outer flange of the coil bobbin 5-1.
Thus, the lead wire holding portion 1 is integrally connected.
Needless to say, the lead wire holding portion 1 may be independent as a separate member from the coil bobbin 5-1. Although not shown, in a configuration in which the lead wire holding portion 1 is separated from the coil bobbin 5-1 and used as a separate member, the lead wire holding portion 1 is fixedly held with a fitting structure with a casing 8 schematically indicated by a broken line in FIG.

1 and a lead wire outlet 2 having a flexible wall 7 provided to face the inner wall 2-1. As shown in FIG. 1, the lead wire 3 connected to the lead terminal 6 is drawn out from the lead wire outlet 2 in such a manner as to be folded back through the tip of the flexible wall 7. When a pulling force is applied to the lead wire 3 from outside in this mounted state, the flexible wall 7
The leading end of the lead wire 3 is bent and approached so as to bite the folded portion of the lead wire 3 so as to be drawn to the inner wall 2-1 at the far end of the lead wire outlet 2. As the flexible wall 7 bends and approaches the inner wall 2-1 of the lead wire outlet, the lead wire 3 sandwiched between the two walls is reliably folded back at the distal end of the flexible wall 7 and the frictional force caused by the sandwiching. , And the removal force can be obtained to the extent that the coating of the lead wire 3 is not broken or the flexible wall 7 is not broken.

る。The lead wire outlet 2 of the lead wire holding part 1 may be formed as a hole as shown in FIG. 5, but it is premised that the lead wire 3 passes through the lead wire 3 and is inserted therethrough. As is well known, it is disadvantageous in terms of workability. As a remedy, it is divided along the arrow as shown in FIG. 5, and as shown in FIG. 3 and FIG. Is divided into two parts, a holding part 1-1 and a holding part 1-2, and a U-shaped groove 2 'is provided in one holding part 1-1 so as to close this opening, and the other holding part 1-2 is The structure used together is also effective.
In this example as well, the holding portions 1-1 and 1-2 may be formed integrally with the coil bobbin 5-1 respectively, and as a separate member, the holding means may be provided with a fitting structure, although not described in detail, or a casing. 8 can be used.
