Product moving implement and display case

In the present invention, the following are provided: a plurality of roller members 10; a base member 5 which includes a bottom plate part and peripheral wall parts and which accommodates the plurality of roller members 10; and a plate-shaped cover member 20 that is detachably arranged at an opening part which is surrounded by the peripheral wall parts. The base member 5 is formed of a material for which: the flexural modulus is 2500MPa-4000MPa; a first parameter, represented by flexural modulus [Mpa] X tensile yield stress [MPa] X thickness [mm]/density [g/cm3]/100000, is 7.00-18.00; and a second parameter, represented by the first parameter X tensile breakage nominal strain [%]/100, is 2.00-10.00.
