PROBLEM TO BE SOLVED: To provide a protective cover which is attached to a sheet-receiving member having a U-shape cross section of a plastic greenhouse and whose structure is designed so as to be simply and easily attached/detached to/from the sheet receiving member. SOLUTION: The protective cover is attached to the sheet-receiving member having a U-shape cross section of the plastic house, and includes a long and thin flexible sheet made of flexible resin, and right and left hard cover parts made of resin: wherein the lower-surface center part of the right and left hard cover parts are joined to both sides of the right and left parts of the flexible sheet part to superimpose the hard cover part on the flexible sheet part; the length of the hard cover part is almost the same as the length of the sheet-receiving member; and the width of the hard cover part is wider than that of the opening of the groove of the sheet-receiving member.
