本考案はオートバイその他の自動２輪車におけ
るエンジンの冷却水通路装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling water passage device for an engine in a motorcycle or other two-wheeled vehicle.
従来この種装置として、前後の車輪を有する車
体の中間部にエンジンとその前方上部のラジエー

すべく作業に手数を要する不都合を伴う。 Conventionally, this type of device includes an engine in the middle of a vehicle body having front and rear wheels, a radiator in the upper front part of the engine, and a water pump in the rear part, and the radiator and water pump are connected to each other by a cooling water supply passage and a return passage. It is known that the radiator communicates with the radiator to form a circulation path, but in this case, the drain hole for draining water is generally installed at the bottom of the radiator. However, some amount of cooling water remains in low places in the circulation path, which causes the inconvenience of requiring laborious work to remove it.

ンジン３の前部の過給機を示す。 The purpose of the present invention is to obtain a device that does not have such inconveniences, and includes an engine 3 located in the middle of a vehicle body 2 having front and rear wheels 1, 1.
The radiator 4 and the pump 5 are connected to an upper cooling water supply passage 6 including a water passage inside the engine 3, and a water pump 5 at the rear of the engine 3. In a type that communicates with each other via a cooling water return passage 7 extending from the side, a drain hole 8 is provided at the lowest position in the middle of the return passage 7. The drain hole 8 opens downward, and a resin screw 8a is inserted from below through a packing 8b to keep it closed at all times. It is preferable to have a low position,
In this way, it is provided on the side of the vehicle body 2 that has the side stand 9. In the drawing, reference numeral 10 indicates a fuel tank 11 above the engine 3, a seat for a passenger behind it, 12 a fairing in front, and 13 a supercharger at the front of the engine 3.
このように本考案によるときはドレン孔８を下

都合がない効果を有する。 In this way, according to the present invention, the drain hole 8 is provided at the lowest position of the lower return passage 7, and by opening the hole 8, the entire amount of internal cooling water can be discharged from this point, unlike the conventional method. However, it has an effect without the above-mentioned disadvantages.
