ウォータポンプカバー26に当接する虞れがあった。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cooling water guide structure for a water-cooled carrot, and in particular, to a water pump and a passage structure for cooling water guided by the water pump. "Prior art" Figure g2 is a water-cooled engine 1 showing a conventional cooling water guide structure.
This is a partial view of 0, especially showing the water-cooled carrot installed in the motorcycle and wheels. □ On the side of the crankcase 12 of this engine 10, there is a side cover 1 that covers the clutch 14.
6 is arranged, and in front of it is a water pump 18.
The impeller 20 of the T-turn 18 is fixed to the tip of the crankshaft 22 by a fastening member y such as a bolt 24, and its blade 20α faces the side of the side cover 16. It is located in Further, a water pump cover 26 that covers the impeller 9-20 is arranged on the side of the side cover 16. A cooling water passage 28 is formed in the front of the side cover 16,
Cooling water (arrow mark) supplied from the water pump 18 is connected to the crankcase 12 through the water jacket 30.
Therefore, according to the above-mentioned cooling water guide structure, the cooling water cooled by the undisclosed radiator passes through the pipe 34 and the cooling water passage 28 to the water pump 18. is attracted to,
Further, the water pump 18 supplies the water to the water jacket 30 via the cooling water passage 32. However, according to the conventional cooling water guide structure described above, the cooling water is supplied to the quarter cup (-, 26) that covers the water pump 18. Since the passage 28 had to be formed, the width W of the engine lO was widened by that amount in the direction perpendicular to the direction of travel of the vehicle (arrow B). If the width W is wide (for example, the footrest (not shown) and the rear brake lever 36
In a vehicle where the toe of the boot 38 is located at the front of the vehicle (a so-called American type motorcycle in which the rider rides with his/her legs positioned forward), there is a risk that the toe of the boot 38 may come into contact with the water pump cover 26 when operating the rear brake. there were.

2 has a water pump 42 disposed at its tip. The impeller 44 is fixed to the tip of the shaft 22α extending from the tip of the crankshaft 22 by fastening means such as a flat head screw 46. On the other hand, a side cover 48 that covers the side of the crankcase 12 is formed with a fitting hole 50 through which the shaft 22α is inserted, and a shaft 22g is supported on the side of the crankcase 12 of the fitting hole 50. A bearing 52 and a seal 54 for sealing the ζ-tuned V-wheel housed in the crankcase 12 and preventing leakage of cooling water are respectively fitted. The side cover 48 also includes an impeller 44 in the insertion hole 50.
A cooling water passage 51 is formed which opens on the suction side of the blade 44g, that is, on the side of the engine side in the rotation range of the blade 44g, and a cooling water passage 32 that opens on the discharge side of the impeller 44, that is, on the same side of the rotation range of the blade 44g. has been done.

が出来る0(Effects of the Invention) This invention provides a water pump in which the suction part of the impeller is mounted toward the engine side, that is, in the opposite direction to the conventional one.
In addition, because the cooling water passage that guides cooling water to the water pump is formed in the side cover that covers the side of the crankcase, the cooling water passage does not protrude to the side of the crankcase, making the carrot width extremely narrow. This makes it easier to operate the rear brake pedal and reduces the front projected area, making it possible to create a slim and compact motorcycle.
