以上のように構成した本発明に係るエンジンの冷却 部構造によれば、 エン ジン 1 の吸風側の機台 2上に、 壁面のように 1 枚の仕切板 6 を立てて固定し、 この仕 切板 6の一方の面にラジェ一夕 3 とシュラウ ド 7を、 他方の面にオイルクーラ 4 とコ ンデンサ 5 をそれぞれ 取付けるようにしたので、 前記複数の部材を取付ける ための構造を極めて簡単で廉価に構成するこ とができ る Cooling of the engine according to the present invention configured as described above According to the part structure, one partition plate 6 like a wall surface is fixed upright on the machine base 2 on the air intake side of the engine 1, and one side of this partition plate 6 And the shroud 7 and the oil cooler 4 and the capacitor 5 on the other surface, respectively, so that the structure for mounting the plurality of members can be made extremely simple and inexpensive.
また、 前記の構成によって同一の機台 2を利用して. 異なる仕様や大きさのエンジン 1 を搭載して部品の共 通化の設計に伴い、 それに応じて異なる仕様や大きさ のラジェ一夕 3やオイルクーラ 4、 並びにコ ンデンサ 5 に対しても互換性を持たせ、 1 枚の仕切板 6 を使用 して簡単に、 能率よ く 取付けるこ とができる。  In addition, the same frame 2 is used by the above-described configuration. The engine 1 of different specification and size is mounted, and with the design of the common parts, the Rage 1 of different specification and size 3 is set accordingly. It is compatible with the oil cooler 4 and the capacitor 5 and can be easily and efficiently installed using one partition plate 6.
更に、 コ ンデンサ 5 は、 オイルクーラ 4 の両側に設 けた取付片 8 を介して前記仕切板 6 に取付けられるの で、 両者の関係位置を適切に位置決めしながら、 簡単 に取付けるこ とができる等の利点がある。  Further, since the capacitor 5 is attached to the partition plate 6 via the attachment pieces 8 provided on both sides of the oil cooler 4, it is possible to easily attach the capacitor 5 while appropriately positioning the relationship between the two. There are advantages.
以上の説明から明らかなように本発明によるェンジ ンの冷却部構造は、 エン ジ ン 1 の冷却フ ァ ン 1 b の吸 風側で機台 2上に植立した 1 枚の仕切板 6 の表面にォ イルクーラ 4 を直接的に取付け、 更に裏面にラジェ一 夕 3 とシュラウ ド 7を取付けるように形成したので、 取付構造を簡素化して廉価なェンジンの冷却部構造を 提供するこ とができる。 また、 機台 2上に植立した 1 枚の仕切板 6 に、 取付 片 8 を介してコ ンデンサ 5 を取付けるこ とにより、 ォ イルクーラ 4 との位置決めを適正に維持させるこ とが できる。 As is clear from the above description, the engine cooling unit structure according to the present invention is composed of one partition plate 6 erected on the machine base 2 on the suction side of the cooling fan 1b of the engine 1. Since the oil cooler 4 is directly attached to the front surface and the radiator 3 and the shroud 7 are attached to the rear surface, the installation structure can be simplified and an inexpensive engine cooling structure can be provided. . In addition, by mounting the capacitor 5 to the one partition plate 6 laid on the machine base 2 via the mounting piece 8, the positioning with the coil cooler 4 can be maintained properly.
更に前記仕切板 6 の一方の面にラジェ一夕 3 とシュ ラウ ド 7を、 他方の面にオイルクーラ 4 とコ ンデンサ 5 を配置するこ とによって重量バラ ンスを図って振動 に対して強固に、 これらの部材を機台 2上に支持する こ とができる。  Further, by placing the radiator 3 and the shroud 7 on one surface of the partition plate 6 and the oil cooler 4 and the capacitor 5 on the other surface, a weight balance is achieved and the vibration plate is firmly resistant to vibration. However, these members can be supported on the machine base 2.
