<P>PROBLEM TO BE SOLVED: To provide a tray for conveying a work which can be stacked even when the accuracy of components and accuracy of assembling fluctuate, and can suppress accumulation of displacement between the trays stacked to the minimum by regulating the trays to the minimum clearance after being stacked. <P>SOLUTION: The tray 1 for conveying the work is used for conveying a substrate S, and includes crosspieces 4, an outer frame 2, and a plurality of resin blocks 8. The crosspieces 4 have a work placing face for placing the substrate S. The outer frame 2 supports the crosspieces 4. A plurality of the resin blocks 8 are provided on the outer frame 2, and perform positioning of the other tray 1 for conveying the work to be stacked. The resin block 8 has a projecting part 21 and a recessed part 22 into which the projecting part 21 of the resin block 8 of the other tray 1 for conveying the work enters. A plurality of the resin blocks 8 have three pieces of first resin blocks 8A arranged without being arranged in a straight line. The recessed parts 22 of at least two pieces of the first resin blocks 8A among three pieces of the first resin blocks 8A are channels extended linearly to allow the movement of the projecting parts 21 in the straight line direction. <P>COPYRIGHT: (C)2009,JPO&INPIT |
