【考案の詳細な説明】
本考案は自動車用その他のトランスミッションにおける
ブリーザ装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a breather device for automotive and other transmissions.

この場合該通路は該ケース内のオイルの流出を防止すべ
く迷路に作られる式を一般としたもので、その構造が複
雑であり、比較的高価となる不都合を伴う。Conventionally, in this type of device, a type in which the inside of the mission case is communicated with the outside via a breather passage is known.
In this case, the passage is generally constructed in a labyrinth manner to prevent oil from flowing out of the case, which has the disadvantage of being complicated in structure and relatively expensive.

形成させたことを特徴とする。The purpose of the present invention is to obtain a device free of such inconveniences.In a breather device that communicates the inside of a mission case 1 with the outside via a breather passage 2, the rotating shaft 3 in the case 1 is A breather chamber 2a having a substantially conical hole 4 formed in the end face and a substantially conical protruding end 5 inserted into the hole 4 with a gap is provided in the case 1, and the case 1 is provided in the breather chamber 2a. A drain hole 2e opening inward and a breather tube 2b protruding outside the case 1 are provided,
A feature is that the breather device 2 is formed through the breather tube 2b.
図示のものでは該ブリーザ通路２をブリーザチューブ２
ｂとこれに連るブリーザホース２Ｃとで構成させた。In the illustrated example, the breather passage 2 is connected to the breather tube 2.
b and a breather hose 2C connected thereto.
該廻転軸３としては、例えばカウンタシャフトを採用す
るもので、外周に歯車６，６と、その中間に軸受７とを
備える型式とする。The rotating shaft 3 is, for example, a countershaft, and is of a type having gears 6, 6 on the outer periphery and a bearing 7 in the middle thereof.
尚前記したブリーザホース２Ｃはその外端にオリフィス
２ｄを備えるものとし、更に前記したブリーザ室２ａは
その座面にドレン孔２ｅを備え、多少とも該室２ａ内に
進入するオイルはこれを介して該ケース１内に戻される
ようにした。The above-described breather hose 2C is provided with an orifice 2d at its outer end, and the above-described breather chamber 2a is further provided with a drain hole 2e on its seat surface, through which any oil entering the chamber 2a may enter. It was arranged to be returned to the case 1.
その作動を説明するに、廻転軸３の端面の孔４部分は、
該軸３の廻転に伴う遠心力によりオイルが吹き飛ばされ

ブリーザ通路２にはオイルの進入がなく、換言すれば該
通路２を介してオイル漏れがない。To explain its operation, the hole 4 portion on the end face of the rotating shaft 3 is
The oil is blown away by the centrifugal force caused by the rotation of the shaft 3, and thus no oil enters the breather passage 2 whose upstream end 5 opens. There is no oil leakage.

を有する。In this way, according to the present invention, a substantially conical hole 4 is formed in the end surface of the rotating shaft 3 in the transmission case 1, and a substantially conical protruding end 5 is inserted into the hole 4 with a gap therebetween, and the case 1
A breather chamber 2a having a drain hole 2e opening inward and a breather tube 2b protruding outside the case 1 is installed in the case 1.
a breather tube 2b of the breather chamber 2a;
Since the breather passage 2 is formed through the
The outflow of oil through the breather passage 2 can be easily and reliably prevented, and the breather chamber 2a is formed by expanding a projecting end 5 which is inserted into a substantially conical hole on the end face of the rotating shaft. This has advantages such as ease of formation.
