Abstract: Provided is a belt cover of an internal combustion engine having ease of attachment and detachment and sealability. A belt cover structure for an internal combustion engine includes an oil pump case OP and a lower cover 9 that cover a timing belt TB, and a side mount bracket 8 that is adjacent to an upper side of the lower cover 9 and is held by a cylinder block CB. Mating surfaces 96c and 86c that are aligned with each other are respectively formed on the lower cover 9 and the side mount bracket 8. A lower seal member 41 is disposed on the mating surface 96c, and the mating surface 86c is configured to cover the mating surface 96c from the outside. The lower cover 9 and the side mount bracket 8 are fixed in a state where the mating surface 86c of the side mount bracket 8 is pressed against the mating surface 96c of the lower cover 9 via the seal member 41.

Abstract: The electrochemical module is formed by stacking a plurality of membrane electrode assemblies having electrolyte membranes, anodes and cathodes. The plurality of membrane electrode assemblies are stacked so that a first region where the anodes face each other and a second region where the cathodes face each other appear alternately in the stacking direction. Further, at least one of the first region and the second region includes a common flow path shared by two adjacent membrane electrode assemblies.

The seal structure of the belt cover for the internal combustion engine according to the present invention includes: an inside cover member disposed on a side of the body of the internal combustion engine; and an outside cover member disposed on a side opposite to the body of the internal combustion engine, and accommodating a timing belt TB in a liquid-tight state together with the inside cover member. The outside cover member is divided into an upper outside cover 4 and a lower outside cover 5. A first seal is formed between the upper outside cover 4 and the inside cover member. A second seal is formed between the upper outside cover 4 and the lower outside cover 5.

Abstract: A belt cover for an internal combustion engine is provided, and the belt cover efficiently discharges water from a drain hole and has good sealing performance. A water pump 30, which is disposed on one side surface of a cylinder block CB, and which includes a drain hole 35, an oil pump case OP, which covers the inside of a timing belt TB, and a lower cover 9, which covers the outside of the timing belt TB are included. The oil pump case OP and the lower cover 9 are fixed with each other through a seal member 40, and constitute a lower case 90. A guide rib 91 and a discharge port 92 are formed inside the lower case 90, the guide rib 91 being for guiding drained water from the drain hole 35, while separating from the timing belt TB, the discharge port 92 being for discharging the drained water from the lower case 90 at a bottom end of the lower case 90, and the drained water from the drain hole 35 is guided by the guide rib 91 toward the discharge port 92.

Abstract: 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.
