PROBLEM TO BE SOLVED: To provide a cooling structure that can sufficiently cool a gear wheel even when a nozzle jets an insufficient amount of an oil flow jetted from the nozzle.SOLUTION: A gear wheel cooling structure includes: the gear wheel including multiple teeth extending in a specific direction; and the nozzle for jetting the oil toward a tooth flank of the gear wheel. The nozzle extends in the specific direction in a width narrower than an interval between tips of the multiple teeth.SELECTED DRAWING: Figure 1 【課題】ノズルから噴射されるオイルの流量が少なくても歯車を十分に冷却することができる冷却構造を提供する。【解決手段】歯車の冷却構造は、特定方向に延びる複数の歯を含む歯車と、歯車の歯面へ向かってオイルを噴射するノズルと、を備え、ノズルは、複数の歯の先端同士の間の間隔よりも狭い幅で、特定方向に延びている。【選択図】図１
