Summary of the invention
(problem that first execution mode of the present invention will solve)
Wherein, when engine start, bearing bracket stand 104 makes its peristome distortion to support 107 application of forces in the past.When engine start, when motor 101 drove crank axle, bigger load was carried on the rotating shaft 109 from engine one side.Rotating shaft 109 crooked or vibration owing to this load is so bigger power is carried on the latch part 118 by the front axle bolster 104 of supporting breach diametrically.But as can be seen from Figure 10, latch part 118 forms thinlyyer than the wall at other positions, so this power may make latch part 118 distortion.If latch part 118 distortion then produce the gap between front axle bolster 104 and support 107, thereby the problem that exists armature 103 and magnet 108 to interfere.
On the other hand, as mentioned above, because support 107 is to form by cutting commercially available tubing, so exist the external diameter of motor 101 to be subjected to the problem of the restriction of commercially available pipe diameter.Generally, the size of outer diameter of steel pipes is set by standard stages such as JIS, adopts the preferred outside diameter of motor surely and differ.Therefore, have to set the slightly big external diameter close sometimes, run counter to thereby exist with the miniaturization and of motor with preferred outside diameter, and the problem of costs raisings such as fee of material and portage.
(problem that second embodiment of the invention will solve)
In addition, according to the difference of car type, the installation site of starting motor on car body is also different, thereby setting angle and position that motor is fixed on the installation fagging on the car body are also moved.Fagging is installed generally on the rear axle bolster, is formed, as shown in figure 12,, also be located at sometimes on the rear axle bolster outer peripheral face except being located on the end face.In the latter case, if the position deviation direction of principal axis of fagging is installed, then the rear axle bolster may also will become longer thereupon.On the other hand, the position of brush carriage 116 is by the relation of it and commutator 112 and determine.Therefore, make rear axle bolster 105 elongated if keep the brush carriage position, then the also corresponding inboard that is set at bearing bracket stand, the installation site of brush carriage.
But if brush carriage 116 is configured in the inboard of rear axle bolster as mentioned above, then the claw of the location usefulness between the magnet brush also needs correspondingly elongated.That is, claw need be extended to the breach 127 of support 107 ends from the inboard of rear axle bolster.Consider that from precision and intensity aspect Chang claw is not preferred like this, in addition, also has the problem that makes complex-shapedization of brush carriage and the more materials of needs in order to form claw.In addition, in the motor that does not use brush carriage, this mode can not be adopted, and the locate mode that replaces it will be studied.
