Abstract: An article moving device includes a plurality of roller members, a base member which has a bottom plate section and a peripheral wall section and accommodates the plurality of roller members, and a plate-shaped cover member which is detachably attached to the peripheral wall section so as to cover an opening section surrounded by the peripheral wall section, wherein the base member is formed of a material having a flexural modulus of 2500 MPa to 4000 MPa, a first parameter of 7.00 to 18.00, as calculated by the formula: flexural modulus (MPa)×yield stress in tension (MPa)×thickness (mm)/density (g/cm3)/100000, and a second parameter of 2.00 to 10.00, as calculated by the formula: first parameter×nominal tensile strain at break (%)/100.
