PROBLEM TO BE SOLVED: To improve knocking detection accuracy of a cylinder block of a V-type internal combustion engine. SOLUTION: In this knocking sensor mounting structure, a pair of ribs 24, 25 having origins on head bolt boss parts 18F, 18G, 18J, 18K formed between adjoining cylinders of opposing wall parts 22 of a pair of banks 12 inclined at predetermined angles and connecting the opposing wall parts 22 on both banks 12 are crossed in an X-shape on a center crossing part 28. A pair of knocking sensor mounting parts 30, 31 on which the knocking sensors are mounted are arranged at a root part of an engine rear side where the ribs 24, 25 connect to the opposing wall part 22.
