本考案は、例えば農作業機における作業装置側
の板金製伝動ケースを本機側のミツシヨンケース
側壁部へ取付けるための構造改良に関する。[Detailed Description of the Invention] The present invention relates to a structural improvement for attaching, for example, a sheet metal transmission case on the working device side of an agricultural machine to the side wall of the transmission case on the machine side.

をミツシヨンケース０４に固着連結していた。 The conventionally known structure for attaching the sheet metal transmission case to the transmission case is as follows:
As shown in FIG. 3, a bearing holder part 03a that fits and holds a bearing 03 that rotatably supports a transmission wheel body 02 such as a sprocket located in a transmission case 01 made of sheet metal is attached to the case 01.
A cylindrical boss 07 that fits into an outwardly opening cylindrical boss 04a formed on the side wall 04A of the mission case 04 is integrally formed on the tip thereof. The transmission case 01 is configured such that the protruding cylindrical boss 07 is fitted into the cylindrical boss portion 04a on the transmission case 04 side.
was firmly connected to transmission case 04.

不利であつた。 In this case, the cylindrical boss 07 described above has a thin wall and is formed to protrude from the bearing holder part 03a with a step, so that when an external force acting on the transmission case 01 in the installed state is concentrated on the fitting part. However, the protruding cylindrical boss 07 may be deformed or damaged, resulting in strength problems.Furthermore, a space corresponding to the protruding fitting portion is required, which is disadvantageous in terms of space.
本考案はかかる実情に鑑み、簡単な改良により
強度的にもスペース面でも有利な状態の取付けが
可能なものを提供する点に目的を有する。 In view of these circumstances, the present invention has an object to provide a device that can be mounted in an advantageous state in terms of strength and space through simple improvements.

の作用効果を奏する。 Pertaining to the present invention, which was made to achieve the above purpose,
By bending one side of the sheet metal transmission case,
A bearing holder portion protruding outward is formed, and a bearing for rotatably supporting the transmission wheel positioned within the sheet metal transmission case is fitted and held on the inner peripheral surface of the bearing holder portion. , an outer peripheral surface portion of the bearing holder portion is fitted into a cylindrical boss portion with an outward opening formed on a side wall portion of the transmission case, and the bearing holder portion is held between the bearing and the cylindrical boss portion. In this state, the transmission case is fixed to the transmission case, and this structure provides the following effects.
即ち、従来のようにベアリングホルダー部の先
端部分に別途の筒状ボスを形成し、この筒状ボス

直接筒状ボス部に嵌合して固着する構造であるの
で、伝動ケースとミツシヨンケースとを極力近接
して固着することができ、スペース面で有利に、
つまり、全体をコンパクト化することができる。 That is, instead of forming a separate cylindrical boss at the tip of the bearing holder part and fitting this cylindrical boss into the cylindrical boss part formed on the side wall of the transmission case as in the past, the bearing holder part Since it has a structure that is directly fitted and fixed to the cylindrical boss part, the transmission case and transmission case can be fixed as close as possible, which is advantageous in terms of space.
In other words, the entire structure can be made more compact.

ースをミツシヨンケースに堅固に取付けることが
できるようになつた。 This bearing holder part is formed by bending a relatively thin sheet metal transmission case, and is easily deformed and damaged. It has a structure in which a rigid bearing is fitted, a cylindrical boss part is fitted onto the outer circumferential surface, and a relatively thin bearing holder part is sandwiched between the parts, so it is possible to obtain greater fixing strength than before. , it became possible to securely attach the sheet metal transmission case to the transmission case.

構造に限定されるものではない。 As shown in Figs. 1 and 2, a bearing 3 that rotatably supports a transmission wheel body 2 such as a chain sprocket, which is located inside a sheet metal transmission case 1 for transmitting power to the working equipment side, is installed inside the case. The bearing holder part 3a that is fitted and held on the peripheral surface is attached to the case 1.
The bearing holder portion 3a is integrally formed to protrude outward by bending, and the protruding bearing holder portion 3a is fitted into the outward opening cylindrical boss portion 4a formed on the side wall portion 4A of the mission case 4. The transmission case 1 is fixed to the transmission case 4 by tightening bolts 6 inserted through the flange portion of the transmission case 1 to bosses 5 fixed to the side wall portion 4A of the transmission case 4. Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
