PURPOSE: To install a panel between frame members on both the sides of the same easily by forming a fitting part on both the sides of the frame member and installing a presser member.

CONSTITUTION: In the frame body of a carrier device where multiple frame members are disposed at comers and panels are disposed between neighboring frame members, the edge of one of panels 25, 26 is inserted in a fitting part 32 of the frame member 22 on one side to be fitted. Next, while the panels 25, 26 are being deflected, the edge on the other side is inserted in the fitting part 32 of the frame member 22 on the other side, so that both edges are held in such a condition as they are fitted in the fitting parts 32 of the frame members 22 on both sides by the elastic action of the panels 25, 26 respectively. Moreover, a presser member 51 is installed to a mounting part 34 of the frame member 22, so that the presser member 51 projects from a locking part 33 of the fitting part 32 and adheres to the respective outer surfaces of the edges of the panels 25, 26.
