ストの侵入を完全に防ぐことは困難であった。(Problems to be Solved by the Invention) However, in such a conventional structure with one dust cover removal part, the part on the case side into which the peripheral edge of the dust cover fits is cut to form a cylindrical shape. Since a cover fitting part must be formed, case processing is complicated, and since the gap between the cover and the case is straight, it is difficult to completely prevent dust from entering.

っている。First, to explain the structure, 1 is a case, and inside the case 1, a front drive shaft 5 integrally equipped with a gear 4 is rotatably supported by a bearing 2.3. The front drive shaft 5 is taken out on the left side,
The connecting flange 6 is fixed by tightening the nut against the screw shaft. A dust cover 8 is fixed by welding or the like to the outer circumferential step of the connecting flange 6 on the case 1 side, and covers the shaft extraction portion of the case 1 provided with the seal 7.

い。The annular U-shaped groove 10 formed on the end surface of the case 1 is formed by casting t> when molding the case 1, and there is no need to form the annular U-shaped groove 1o by machining.
次に第１図の実施例の作用を説明する。Next, the operation of the embodiment shown in FIG. 1 will be explained.
まずジス１〜カバー８の周縁８ａが入るケース端面の環

低減できる。First, the annular U-shaped groove 10 on the end face of the case into which the circumferential edge 8a of the housing 1 to the cover 8 is inserted is formed by centering during case manufacturing, so cutting is not required and the number of machining steps can be significantly reduced.

ことができる。On the other hand, the peripheral edge 8a of the dust cover 8 is inserted into the annular U-shaped groove 10.
By inserting this, the gap between Jis 1 to Cover 8 and Case 1 is not straight, but has a so-called buffel gap structure that is bent in a U-shape, which prevents dust from getting caught inside the cover compared to the conventional straight gap. It can be difficult to do.

できる。(Effects of the Invention) As explained above, according to the present invention, the dust cover of the transmission that is provided on the input/output shaft flange and covers the gap with the case is attached to the end face of the case opposite to the dust cover. An annular U-shaped groove is formed by casting, and the periphery of the dust cover is positioned within this annular U-shaped groove, so the annular U-shaped groove into which the dust cover fits is formed at the time of manufacturing the case! Since it can be formed at the same time by using a five-way screw, there is no need for cutting, which reduces the number of machining steps.The gap between the cover and case is a U-shaped buff-filled structure, which is different from the conventional straight one. Compared to the gap,
It is possible to more reliably prevent dust l- from being caught inside the cover.
