It is configured by penetrating a space 4 for axial longitudinal travel of 3 in the front-rear direction, opening an oil drain port 5 in the lower portion of the oil pan body 1, and closing the oil drain port 5 with a drain plug 6 so as to be openable and closable.
＜従来技術＞ 上記基本構造において、軸縦走用空間４を形成するため
の具体的な構造として、従来では次のものがある。<Prior Art> In the basic structure described above, as a specific structure for forming the axially traveling space 4, there is conventionally the following structure.
従来例１（第５図・第６図） オイルパン本体１内で、その前端壁15から後端壁16にか
けて細長い円筒体17を設け、円筒体17の筒孔18で前記軸
縦走用空間４を形成したものである。Conventional example 1 (Figs. 5 and 6) An elongated cylindrical body 17 is provided from the front end wall 15 to the rear end wall 16 in the oil pan body 1, and the axial longitudinal space 4 is formed by a cylinder hole 18 of the cylinder body 17. Is formed.
従来例２（第７図・第８図） 底壁９の左右方向の中央部分をその全長に亘って溝状に
凹入形成し、その凹入溝19で前記軸縦走用空間４を形成
したものである。Conventional Example 2 (FIGS. 7 and 8) The center portion of the bottom wall 9 in the left-right direction is formed into a groove shape over the entire length thereof, and the groove for groove 19 forms the space 4 for axial longitudinal travel. It is a thing.
先考案例（第９図〜第11図） 本考案者が本考案に先立って考案したものである。Pre-developed example (Figs. 9 to 11) The present inventor devised prior to the present invention.
上記従来例２の構造において、凹入溝19の前後方向の中
央の下部にオイル連通筒20を架着し、オイルパン本体１
内の左右の下部空間21a・21bが凹入溝壁22で分離されて
いるところをオイル連通筒20で連通させたものである。In the structure of the above-mentioned conventional example 2, the oil communication cylinder 20 is mounted on the lower part of the center of the recessed groove 19 in the front-rear direction, and the oil pan body 1
The left and right lower spaces 21a and 21b in the inside are separated by the recessed groove wall 22 and are communicated with each other by the oil communication cylinder 20.
＜考案が解決しようとする問題点＞ 従来例１（第５図・第６図） イ．細長い円筒体17を鋳造するために、細くて長い中子
を使わなければならないため、オイルパンの鋳造が困難
になり、高価につく。<Problems to be solved by the device> Conventional example 1 (Figs. 5 and 6) a. Since a thin and long core must be used to cast the elongated cylindrical body 17, casting of the oil pan becomes difficult and expensive.
従来例２（第７図・第８図） ロ．オイルパン本体１内の下部空間21a・21bが凹入溝壁
22で分離されるので、正しくオイルドレンするために、
凹入溝壁22の右側の底壁部分にも左側の底壁部分にもオ
イルドレン口５とドレンプラグ６とをそれぞれ１個づつ
設けなければならず、その構造が複雑となり、高価につ
くうえ、オイルドレン時にドレンプラグ６を２個操作し
なければならず、手間がかかる。Conventional example 2 (Figs. 7 and 8) b. Lower spaces 21a and 21b in the oil pan body 1 are recessed groove walls
It will be separated at 22, so in order to properly drain the oil,
One oil drain port 5 and one drain plug 6 must be provided on both the right bottom wall portion and the left bottom wall portion of the recessed groove wall 22, which makes the structure complicated and expensive. It is troublesome to operate two drain plugs 6 when oil is drained.
先考案例（第９図〜第11図） 先考案例では、凹入溝状の軸縦走用空間４を鋳造する時
に、細くて長い中子を不要にできるので、オイルパンを
簡単に安価に鋳造でき、しかも、オイルパン本体１内の
左右の下部空間21a・21bの間をオイルがオイル連通筒20
から行き来できるので、オイルドレン口５とドレンプラ
グ６は２個設ける必要がなく、オイルドレンのための構
造及び操作を簡素化できる点で優れている。Inventive example (Figs. 9 to 11) In the invented example, a thin and long core can be dispensed with when casting the recessed groove-shaped space 4 for axial longitudinal running, so that the oil pan can be easily and inexpensively manufactured. Oil can be cast, and the oil can communicate with the lower space 21a, 21b in the oil pan body 1 between the oil communication cylinders 20.
Since there is no need to provide two oil drain ports 5 and drain plugs 6 because they can be reached from each other, it is advantageous in that the structure and operation for the oil drain can be simplified.
しかし、次の問題が残る。However, the following problems remain.
ハ．オイル連通筒20は他の部分よりも早く冷却すること
から、凝固が早く、鋳造後に引張り応力が残留するた
め、他物が衝突した時に破損し易い。この残留引張り応
力を取除くために、オイルパン全体を焼ならし処理する
必要があり、高価につく。C. Since the oil communication tube 20 cools faster than other parts, it solidifies quickly and tensile stress remains after casting, so it is easily damaged when another object collides. In order to remove this residual tensile stress, it is necessary to normalize the entire oil pan, which is expensive.
ニ．オイル連通筒20は焼ならし処理しても細くて弱いた
め、他物から衝撃力を受けた時に破損し易い。D. Since the oil communication tube 20 is thin and weak even after normalizing, it is easily damaged when it receives an impact force from another object.
例えば、エンジンの製造ライン上で、ローラー搬送装置
の曲り角の部分にはボール搬送装置が設けられている場
合があり、ここをエンジンが通過する時にオイル連通筒
20が搬送ボールに衝突して破損するおそれがある。For example, on the engine manufacturing line, there may be a case where a ball transfer device is provided at the corner of the roller transfer device. When the engine passes through the ball transfer device, the oil communication cylinder
20 may collide with the transport ball and be damaged.
