Abstract: PROBLEM TO BE SOLVED: To provide a decorative plate used also as a coupling (hereinafter referred to as a coupling-decorative plate) which absorbs vibration propagating from one pipeline to another and reduces the propagation of vibration to the blindfolds of perforations or to the periphery of perforations by integrally molding, from an elastic material, a pipe section as a coupling having the ends connectable to pipelines and a flange section as a decorative plate formed on the outer side of the pipe section. SOLUTION: This coupling-decorative plate 14 comprises a pipe section 15 as a coupling having the ends connectable to pipelines and a flange section 16 as a decorative plate formed on the outside of the pipe 15. For example, when this coupling- decorative plate is used in a disposer 1 having a trap pipe 19 and a lateral branch pipe 9 connected to each other, the vibration of a motor 3 for driving the rotatory blade of a disposer body 2 propagates to the pipes 19, 9.
