In regards to claim 1:
Kunimitsu teaches an engine oil cooling structure of an engine, the engine comprising a crankcase (27), the crankcase being provided with an oil filter mounting chamber having a cylindrical shape (housing filter 90), the cooling structure comprising a water channel (73), a water inlet of the water channel communicating with a water pump (66), the crankcase being provided with a main oil channel (91) for conveying engine oil, wherein the crankcase is further provided with a heat conducting thin wall (Shown below in annotated Figure 6), an inner cavity of the heat conducting thin wall forms the oil filter mounting chamber, the oil filter mounting chamber communicates with the main oil channel (Shown in Figure 4), the water channel is arranged around an outer side wall of the heat conducting thin wall (Shown in Figure 6), and a water outlet of the water channel communicates with a cooling water channel arranged in the same direction as and adjacent to the main oil channel (the water channel as shown below in annotated Figure 6 flows both horizontally and vertically, and Figure 4 of Kunimitsu shows the oil passage 91 flowing vertically and horizontally into the oil filter chamber).
