ABSTRACT:
A synthetic resin cover having a grip is mounted on the upper surface of an upper case board that constitutes part of the fixing housing and covers the upper side of the fixing roller of an image forming machine. The cover has a cover body and attaching portions, the lower surfaces of the attaching portions being higher than the lower surface of the cover body. The attaching portion includes a cylindrical portion having a fastening member insertion hole and a receiving portion provided at the lower end of the cylindrical portion and having an insertion hole. The fastening member has a head portion of a diameter larger than that of the insertion hole formed in the receiving portion, a columnar portion connected to the head portion and having a diameter smaller than that of the insertion hole but is larger than that of a threaded hole formed in the upper case board, and a threaded portion that is connected to the columnar portion and that can be screwed into the threaded hole formed in the upper case board. The length of the columnar portion is greater than the thickness of the receiving portion and is related to the distance of from the upper surface of the receiving portion to the lower surface of the cover body.
