PURPOSE:To prevent a bottom plate fixing part from cracking to pieces, by installing each of reinforcement parts being large in expansion resistance in place nearby the front and rear ends of the bottom plate, while attaching these parts to a bucket frame as a structural formation, in case of an elevator bucket for conveying an adhesive substance. CONSTITUTION:Each of reinforcement parts 11, which are strong in expansion resistance and interposes each of core materials 11a of a woven fabric or the like, is installed in the front and rear ends of an expansile, flexible bottom plate 10 and fitly sandwiched between a front joint plate 2 and a front pressure plate 6 composed of a rigid material each as well as between a rear joint plate 3 and a rear pressure plate 8. With this constitution, these reinforcement parts 11 and 11 where the bottom plate 10 expands and contracts according to the resistance of a conveyed load running to and from a bucket, prevent any deformation of the bottom plate, thus cracking and breakdown can be checked. |
