Generally, a two-wheeled motor vehicle usually has a crankcase disposed on the lower wheel of the two-wheeled motor vehicle to drive the two-wheeled motor vehicle through the transmission member inside the crankcase, so that the two-wheeled motor vehicle can advance. However, in order to protect the transmission components such as the crankshaft and the clutch inside the crankcase of the two-wheeled motor vehicle, in addition to the crankcase, a crankcase cover is provided to shield the crankcase to protect the transmission components inside the drive axle box.

However, when the user is riding a two-wheeled motor vehicle, foreign matter such as dust in the environment or rainwater when it rains easily invades into the crankcase, causing damage to the transmission member inside the crankcase, and the durability is lowered. Therefore, in order to protect the transmission parts inside the crankcase and increase the durability of the transmission parts, a crankcase cover is produced, which can completely shield the crankcase to prevent water or dust from invading, but the disadvantage is that the crankcase cover will be complete. Covering the crankcase, the external cold air is not easy to enter the crankcase, and the heat energy generated by the transmission parts is not easily dissipated, which makes the transmission parts less difficult to heat, resulting in damage to the transmission parts due to excessive temperature, resulting in transmission parts. The durability is reduced.

Therefore, how to improve the durability and heat dissipation of the two-wheeled vehicle transmission parts is a very important part. Therefore, in addition to the waterproof and anti-dust effects, a good crankcase cover should have good heat dissipation efficiency.
