ェーハ抑えを提供するものである。However, each of the wafer holders shown in FIGS. 5, 6 and 8 is a vertical or cantilevered elastic piece having only one end fixed to a lid or a support frame. The structure that supports the elastic piece tends to cause creep deformation at the bent portion of the elastic piece.Especially, when the wafer is stored for a long time, the repulsive force of the elastic piece decreases due to the creep deformation, the wafer holding force weakens, and the wafer is transported. The wafer rotates and rattles, causing rubbing,
There was a high possibility that the wafer would be contaminated by dust generated by abrasion of the wafer or the wafer holder. In this regard, the arcuate elastic piece i shown in FIG. 7 is held on both sides, so there is no danger of creep deformation. However, since it is structurally covering the entire upper surface of the wafer, this wafer restraint is an obstacle. ,
The number of wafers stored in the container cannot be checked from the outside of the lid, and there is a disadvantage that workability is significantly impaired. Furthermore, the shape of the wafer W, as a method for indicating the reference position, a notch type W 1 with a lack only outright the portion of the top portion as shown in FIG. 6, the upper shown in FIG. 8 becomes flat since there is a orientation flat type W 2, a difference in the holding power of both systems depending on the shape of the wafer is suppressed occurs, while in the other be happy there is a problem that dust pollution caused by the rotation and backlash of the wafer occurs . Therefore,
SUMMARY OF THE INVENTION It is an object of the present invention to provide a wafer holder for a wafer storage container which does not cause creep deformation or impair workability and does not affect the holding force even if the shape of the wafer changes.

え。A wafer holder mounted on a bottom surface of a lid and elastically supporting an upper edge of each wafer housed in an inner box has a rectangular support frame, and an arrangement direction of wafers in the support frame. And two oppositely arranged leaf-spring-like elastic members having their respective bases connected to two opposing sides parallel to each other . Each of the elastic members is within 2 to 5 ° with respect to a perpendicular to each other from the base .
After descending at an angle inclined to the side, draw R
Rise inward, then incline 2-5 degrees inward with respect to the vertical
Ascends at an angle and bends in a U-shape reaching the tip , the width direction branches in a comb shape, and each tip is the lid.
Wafer suppress the wafer carrier, characterized in that formed by engaging in contact with the bottom surface in the engaging portion provided on the bottom surface.
