摘要： PROBLEM TO BE SOLVED: To provide cooling structure for a belt chamber of a motorcycle, in which increase in temperature in the belt chamber is suppressed, by taking a necessary and sufficient amount of outside air in the belt chamber to use the outside air for cooling each sections. SOLUTION: In the motorcycle, the belt chamber S accommodates a V-belt- type automatic transmission 21. The V-belt-type automatic transmission is constituted by winding an endless V-belt 40 between a driving pulley 38 disposed to a crankshaft 24 of an engine, and a driven pulley 39 disposed to a driven shaft arranged in parallel with the crankshaft 24. On outer faces of fixed sheaves 46 and moving sheaves of the driven pulley 39 (or at least an outer face of one of moving sheaves 42 of the driving pulley 38), a plurality of fins 46a, 47a are formed to constitute a plurality of cooling fans. These cooling fans take the outside air into the belt chamber S from the inside and outside of the belt chamber S. Accordingly, the cooling structure for the belt chamber of the motorcycle is provided.

摘要： PROBLEM TO BE SOLVED: To provide a reciprocating balancer mechanism of an internal combustion engine capable of minimizing sliding resistance and noise. SOLUTION: In this balancer mechanism of the internal combustion engine by arranging a balancing piston 33 and a connecting rod 34 for balancing in mass with a piston and a connecting rod on the opposite side of the piston with a crankshaft 24 as a boundary, a weight part 34a is formed by extending a small end part of the balancing connecting rod 34 to the anti-crankshaft side of a piston 36. Since the weight part 34a is formed by extending the small end part of the balancing connecting rod 34 to the anti-crankshaft side of the piston 36, the balancing piston 33 can be reduced in weight and a diameter by weight of the weight part 34a, and thus, the sliding resistance and the noise of the balancing piston 33 can be minimized.
