Zusammenfassung:	Provided is a seal structure and a mounting method of a belt cover for an internal combustion engine, the belt cover ensuring good sealability, minimizing detachment and attachment of peripheral pipe and the like when the belt cover is detached and attached, and having excellent maintainability by allowing detachment and attachment of only a necessary cover member. The belt cover includes an inner cover member (3, CH) and an outer cover member on both sides of a timing belt TB, and the outer cover member is divided into upper and lower outer covers (7) and (8) . Sealing in a cylinder bore row direction with respect to the upper outer cover is formed by a first seal member (31) accommodated in a mating surface of the inner cover member, and sealing in a cylinder axis direction with respect to the upper outer cover is formed by a second seal member (33) accommodated in a lower mating surface of the lower outer cover. A predetermined gap is formed between the inner cover member and another component (21), and a plurality of protrusions 34 and 34 for locking the upper outer cover are provided on the lower mating surface of the lower outer cover.
