本発明は始動電動機におけるクラツチチユーブ
とシヤフトの構造の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the structure of a clutch tube and shaft in a starter motor.
従来構造の始動電動機は電動機本体への電流遮
断時一方向性クラツチとともにシヤフト上を摺動

ブはねじスプラインによつて駆動時係合するよう
に設定されている。 In a conventional starter motor, when the current to the motor body is cut off, a spring that pushes back the pinion that slides on the shaft together with the one-way clutch is supported by the inner diameter wall of the clutch tube and a guide provided on the shaft. The shaft and clutch tube are configured to engage in driving engagement by threaded splines.
しかし、このスプリング収納部とねじスプライ
ンの両方を設ける必要からシヤフトとクラツチチ
ユーブの全長は当然長いものとなつて装置自体大
きくなる。 However, since it is necessary to provide both the spring storage portion and the threaded spline, the overall length of the shaft and clutch tube becomes long, and the device itself becomes large.

合はスプリングが破損してしまうという問題があ
る。 Therefore, by making a part of the threaded spline of the clutch tube overlap with the spring storage part so that the spring can be held also in a part of the threaded spline, the overall length of the clutch tube can be shortened by the overlap. It is possible, but the small diameter of the clutch tube's spring storage part and the threaded spline are different, and if there is a step, the spring expanded by the centrifugal force caused by the rotation of the shaft will get stuck in this step. Then, there is a problem that it prevents the shaft from sliding between the clutch tube and, in the worst case, damages the spring.
一方、実公昭55−45899号公報に示される如く、

生じる。 On the other hand, as shown in Utility Model Publication No. 55-45899,
If a part of the spline part of the pinion shaft and the spring storage part are overlapped, the problem of the spring fitting described above will not occur, but if the structure is different from this invention, the clutch When inserting the pinion shaft from the spline side after inserting the spring into the tube, a problem arises in that the spring gets caught in the spline of the pinion shaft, making assembly difficult.

供を目的とするものである。 In order to solve the above-mentioned problems, the present invention aims to provide a starting motor that is small and easy to assemble by providing a threaded spline with a small diameter equal to the inner diameter on the inner diameter wall of the spring housing part of the clutch tube. That is.

has. Reference numeral 8 denotes a shaft having a guide 8a of the spring 5 and a threaded spline 8b on its surface, which engages with the threaded spline 2 of the clutch tube 1 during driving and moves forward. A pinion 9 is connected to the clutch tube 1 and is fitted with a ring gear of an internal combustion engine (not shown).

る。 Next, the operation of the above configuration will be explained. By closing the switch (not shown), the magnetic switch 10 is actuated to energize the motor body 12, and at the same time, the rod 11 pushes out the shaft 8 which has started to rotate by the motor body 12. The shaft 8 then compresses the spring 5 to engage the clutch tube 1 and advance the pinion 9 to engage with the ring gear of the internal combustion engine shown in the figure. At this time, the spring 5 expands in the radial direction due to the centrifugal force caused by the rotation of the shaft 8, but since there is no step in the cylindrical portion 3, which is the inner diameter wall of the clutch tube 1, the spring 5 does not fit, so the shaft 8 slides smoothly. It will be held in

グギヤと離脱して、装置は停止する。 When a switch (not shown) is opened, the current to the motor main body 12 is cut off, and the action of the magnetic switch 10 to push out the rod 11 disappears, so the shaft 8 is pushed back by the repulsive action of the compressed spring 5. It will be done. Therefore, the pinion 9 also separates from the ring gear and the device stops.

長が短縮できる。 Incidentally, since the cylindrical portion 3 of the spring storage portion of the clutch tube 1 is machined with the threaded spline 2, the overall length of the clutch tube 1 and the shaft 8 can be shortened.

た効果がある。 As described above, according to the present invention, the overall length of the clutch tube and shaft is shortened by providing a threaded spline with the same small diameter as the inner diameter on the inner diameter wall of the spring storage portion of the clutch tube. will not bulge and get stuck in the threaded spline of the clutch tube.
The starter motor can be miniaturized, and the spring and the threaded spline of the shaft do not become jammed during assembly, making assembly easy.
