設けられている。 An example of this type of rotation take-off device is a rotation take-off device for driving a speedometer of an automobile. As shown in FIG. 1, a transmission 2 is provided in a transmission case 1, and a drive gear 3 provided in a part of the transmission 2 and a gear member 5 of a rotary take-out device 4 mesh with each other.
A shaft member 6 is coupled to the gear member 5, and a meter cable 7 is connected to one end of the shaft member 6 to drive a speedometer. Lubricating oil for lubricating the transmission 2 is injected into the transmission case 1, and in order to prevent the lubricating oil from leaking,
An oil seal 9 is provided between the shaft member 6 and the holder 8.
従来、回転取出装置のギヤー装置として、中実

が、中実の金属製の軸部材は重いものとなつてし
まい、装置の軽量化という要望に対して好ましい
とは言えない。 Conventionally, as a gear device for a rotary take-out device, a gear member made of metal or synthetic resin is coupled and fixed to a solid metal shaft member, but the solid metal shaft member This results in a heavy weight, which cannot be said to be preferable in response to the desire to reduce the weight of the device.
そこで、中実の金属製の軸部材に代えて中空パ

の連結不良を生じることがある。 Therefore, attempts have been made to use a hollow pipe-shaped metal shaft member instead of a solid metal shaft member, but the lubricating oil inside the transmission case leaks out from the hollow pipe part of the shaft member. In order to prevent leakage or entry of foreign matter from the outside, it is necessary to fit a plug member into the inner hole of the shaft member to seal the inner hole of the shaft member. However, in order to fit the plug member into the inner hole of the shaft member without creating a gap, the plug member must be press-fitted into the inner hole of the shaft member after precisely machining the inner hole of the shaft member. The number of processing steps increases, resulting in a high-cost product with poor productivity. In addition, when a plug member is press-fitted into the inner hole of a shaft member, the press-fitting load may cause the shaft member to bend or bulge in its outer diameter, causing rotation failure in the assembled state and causing problems for the transmission. There is a risk that it may cause. In particular, if a plug member is press-fitted after a shaft member is insert-molded into a synthetic resin gear member, the outer shape of the gear member connection portion of the shaft member will swell, resulting in deformation of the gear member and poor connection between the shaft member and the gear member. This may occur.
本考案はこれらの点に鑑みなされたもので、回

以下添付図面に基づいて本考案を詳細に説明す
る。 The present invention was created in view of these points, and aims to reduce weight by using a hollow pipe for the shaft member in a rotary take-out device, and to provide a gear device that does not have the above-mentioned disadvantages.
The present invention will be described in detail below based on the accompanying drawings.

体に成形されている。 Figures 2, 3, and 4 show an embodiment of the present invention, in which Figure 2 is a perspective view of the shaft member, Figure 3 is a vertical sectional view, and Figure 4 is A of Figure 3. - It is a sectional view along the A line. In FIG. 2, the shaft member 16 is formed of a hollow pipe, and is provided with an inlet 10 that penetrates the hollow pipe in the radial direction. And Figure 3,
As shown in FIG. 4, a gear member 15 formed on the outer periphery of the shaft member 16 and a sealing plug member 11 formed to seal the inside of the inner hole of the shaft member 16 are provided in the shaft member 16. It is integrally molded with synthetic resin through the opening 10.

が軸部材１６に対して抜けたりすることがない。 As described above, since the gear member 15 and the sealing plug member 11 can be molded at the same time, the shaft member 1
The process of machining the inner hole and the press-fitting process of the plug member in step 6 are no longer necessary, reducing the number of machining steps and reducing manufacturing costs.
Further, since the shaft member 16 does not bend or bulge in its outer diameter due to press-fitting of the plug member, there is no possibility of rotation failure after assembly. Furthermore, since the gear member 15 and the sealing plug member 11 are integrally formed through the introduction port 10, the gear member 15 and the sealing plug member 11
will not come off from the shaft member 16.

This improves the inflow of synthetic resin. In this case, if it is desired to improve the coupling strength in the axial direction, the shape of the introduction port 20 may be formed to widen from the end surface of the shaft member.

A recess 12 is formed in the sealing plug member 31. In this way, by providing the recess 12 in the sealing plug member 31, the sealing plug member 31 made of synthetic resin
Since the contraction in the radial direction can be alleviated,
It is possible to prevent the generation of a gap between the shaft member 36 and the sealing plug member 31 due to contraction of the sealing plug member 31, and it is also possible to save the synthetic resin material and further reduce the weight. Effective when the diameter of the inner hole is large.

Since the synthetic resin can be sheared, even if a rotation failure or lock phenomenon occurs due to some reason in the rotation transmission path from the rotation take-out device, by shearing the synthetic resin, the rotation inside the engine can be reduced. It is possible to avoid adverse effects on the parts.

果的である等の効果を有する。 Since the present invention is as described above, in the gear device of the rotary take-out device, the gear member and the sealing plug member are molded from synthetic resin, and a hollow pipe is used for the shaft member, so that the gear device can be made lighter. At the same time, the gear member and the sealing plug member can be molded at the same time, which eliminates the need for machining the inner hole of the shaft member and press-fitting the plug member, reducing the number of processing steps and reducing manufacturing costs. Since there is no bending of the shaft member or bulging of the outer shape due to this, there is no possibility of rotation failure after assembly. Furthermore, since the gear member and the sealing plug member are integrally molded through the inlet, the gear member and the sealing plug member will not come off from the shaft member. In addition, by providing a recess in the sealing plug member, it is possible to alleviate the contraction of the sealing plug member molded from synthetic resin in the radial direction, so that the gap between the shaft member and the sealing plug member due to the contraction of the sealing plug member can be reduced. It is possible to prevent the occurrence of gaps, and it is also possible to save the synthetic resin material and further reduce the weight, which is particularly effective when the diameter of the inner hole of the shaft member is large.
