PROBLEM TO BE SOLVED: To suppress the increase of weight and increase of size in a vehicle width direction in a transmission case structure and a saddle-riding type vehicle.SOLUTION: A transmission case structure 40 comprises a power transmission member transmitting driving force of a driving source to an axle 4a, and a transmission case 50 accommodating the power transmission member. In the transmission case structure 40, the transmission case 50 extends in the longitudinal direction. The transmission case 50 is provided with a first case portion 51 disposed on one side in the longitudinal direction, a second case portion 52 disposed on the opposite side to the first case portion 51, and a third case portion 53 disposed between the first case portion 51 and the second case portion 52 and connected to the first case portion 51 and the second case portion 52. On a lower part of the first case portion 51, a connection portion 51a is provided to be connected to a vehicle body. The second case portion 52 is provided with an axle support part 52a for supporting the axle 4a. Among upper and lower inner wall faces of the third case portion 53, on an inner wall face 53a on a side where the connection portion 51a is provided, a thick wall part 60 is provided extending in the longitudinal direction.SELECTED DRAWING: Figure 3

    【課題】伝達ケース構造及び鞍乗り型車両において、重量増加及び車幅方向の大型化を抑制する。【解決手段】駆動源の駆動力を車軸4aに伝達する動力伝達部材と、動力伝達部材を収容する伝達ケース50と、を備えた伝達ケース構造40において、伝達ケース50は、前後方向に延びており、伝達ケース50には、前後方向で一方側に配置される第一ケース部51と、第一ケース部51とは反対側に配置される第二ケース部52と、第一ケース部51と第二ケース部52との間に配置されかつ第一ケース部51と第二ケース部52とにつながっている第三ケース部53と、が設けられ、第一ケース部51の下部には、車体に連結される連結部51aが設けられ、第二ケース部52には、車軸4aが支持される車軸支持部52aが設けられ、第三ケース部53の上下内壁面のうち連結部51aが設けられた側の内壁面53aには、前後方向に延びる厚肉部60が設けられている。【選択図】図3
