れてしまうという欠点がある。A water-cooled two-stroke engine is equipped with a water pump that forcibly circulates cooling water through the cooling jacket of the cylinder, and an oil pump that supplies lubricating oil to the carburetor. Both pumps are normally powered by gear transmission from the crankshaft. is now entered. However, gear transmission requires the installation of the water pump or oil pump at a position close to the crankshaft, which has the disadvantage that the installation position of the pump is restricted.

という問題がある。Such restrictions on the pump mounting position can be overcome by using a transmission means to wrap the belt around the pump. However, when winding is a transmission means, in order to ensure reliable power transmission, winding always requires a tension adjustment mechanism to adjust the slack of the transmission means, which increases the number of components and complicates the mechanism. There is a problem.

ている。Figure 1.2 shows details of the engine section. The engine 2 has a cooling jacket 12 installed therein so as to extend over both a cylinder body 10 and a cylinder head 11, and a crankshaft 14 is rotationally driven by the reciprocating movement of a piston 13. The crankshaft 14 is provided with a generator 15 at one shaft end and a belt automatic transmission 16 at the other shaft end, and transmits power to the rear wheels 4 via the belt automatic transmission 16. It has become.

る。The water pump 18 forcibly circulates cooling water through the cooling jacket 12, and the oil pump 19 sends lubricating oil to the carburetor 6 to mix it into the fuel. The input shafts of these water pumps 18 and oil pumps 19 each have a boolean l7.
A toothed belt 23 is wound around the pulley 20.21 and a pulley 22 provided at the end of the crankshaft 14, and is driven.

１８ａの上半分と導管１８ｂの上半分とは別の部材とし
て一体に形成され、上記下半分に対し合体されている。The support plate 17 integrally forms the casing 15a of the generator 15, and also connects the lower half of the casing 18a of the water pump 18 and the conduit 1 that sends cooling water from the water pump 18 to the cooling jacket 12 of the cylinder body 10.
The lower half of 8b is integrally formed. On the other hand, the upper half of the casing 18a and the upper half of the conduit 18b are integrally formed as separate members, and are combined with the lower half.

力調節を可能にしている。Further, the support plate 17 supports the mounting plate 24 of the oil pump 19 with a bolt 25 at one end, and the bolt 26 at the other end can be fixed at an arbitrary position along the elongated hole 27 using the bolt 25 as a fulcrum. ing. With such a mounting structure of the mounting plate 24, the position of the pulley 21 of the oil pump 19 can be changed freely, and the tension of the toothed belt 23 can be adjusted by adjusting the position. In other words, in a normal belt drive device, in order to ensure reliable power transmission without belt slack, a special tension adjustment device is always installed to press a tension adjustment pulley or the like against the belt, but as mentioned above, an oil pump By making the mounting position of the toothed belt 19 variable, the tension of the toothed belt 23 can be adjusted without providing the above-mentioned special tension adjustment device.
また、一般に油ポンプ１９の吐出容量は、水ポンプ１８
の吐出容量に比べて著しく小さいため、前者に接続され
る移送パイプは後者のそれに比べて細く可撓性の高いも
のになっている。In general, the discharge capacity of the oil pump 19 is the same as that of the water pump 18.
Since the discharge capacity of the former is significantly smaller than that of the former, the transfer pipe connected to the former is thinner and more flexible than that of the latter.
したがって、上述のように油ポンプ１９の取付位置を可
変自在にしても可撓性の移送パイプが追従するため支障
はな（、またこのように移送パイプが円滑に追従するた
め、ベルトの張力調整を極めて容易に行えるようにして
いる。Therefore, even if the mounting position of the oil pump 19 is made variable as described above, there is no problem because the flexible transfer pipe follows the oil pump 19 (also, since the transfer pipe follows smoothly in this way, the belt tension can be adjusted). This makes it extremely easy to do.
なお、上述した実施例では巻掛は伝動手段として歯付ベ
ルトを使用したが、この巻掛は伝動手段はＶベルトなど

もよい。In the above-described embodiments, a toothed belt was used as a transmission means for winding, but the transmission means for winding may be another belt such as a V-belt, or a chino belt or the like.

ることができる。As described above, the present invention provides a water-cooled engine equipped with a water pump for supplying cooling water and an oil pump for supplying lubricating oil, in which a transmission means is wound between the crankshaft and the water pump and the oil pump. Since the mounting position of the oil pump is made variable by rotating the oil pump, the tension of the winding transmission means can be adjusted by simply adjusting the mounting position of the oil pump as desired, without the need for a special tension adjustment device. Therefore, even if the winding is driven by a transmission means, it can be a simple mechanism with fewer components.
