PROBLEM TO BE SOLVED: To obtain a sufficient effect for absorbing the deformation of a tray main body part while enhancing durability and to make a work tray thin as a whole not only to enhance the degree of freedom of a design but also to reduce useless energy consumption. SOLUTION: A rectangular support frame part 4 and the rectangular tray main body part 5, which is arranged to the inside of the support frame part 4, are provided to a tray part 2 and a plurality of locking pieces 6fs, 6f, etc., are formed to four side parts 5f, etc., of the tray main body part 5 in a protruded state. These locking pieces 6fs, 6f, etc., are respectively locked with a plurality of the locking pieces 7 provided to the support frame part 4 not only to support the tray main body part 5 by the support frame part 4 but also to support the locking pieces (main locking pieces) 6fs, etc., of the respective side parts 5f, etc., so as to freely deform them only in a locking direction by a plurality of the locking holes 7 while supporting the other locking pieces (sub-locking pieces) 6f, etc. so as to freely deform them at least in the locking direction and the direction right-angled thereto by a plurality of the locking holes 7.
