Abstract
A seal structure seals between a cover which closes an opening of a case for housing a part and the case by a sealing member. The cover is provided with an annular recessed portion attached to an end of a peripheral wall forming the opening of the case and a plurality of through-holes penetrating a bottom portion of the recessed portion and spaced apart from each other in a circumferential direction. The sealing member is formed integrally with the cover. The sealing member is integrally provided with a protrusion protruding from a bottom portion over an entire circumference in the recessed portion and an anchor portion engaged with each of the through-holes to fix the sealing member to the cover. Between at least the anchor portions in the recessed portion, a projecting portion for closing the gap between the protrusion and an inner wall of the recessed portion is provided.
