なるものである。(H) Effects According to the present invention, it is possible to simultaneously absorb the vibrations generated when the blower motor is driven and to prevent the influence of heat generation on the inside of the refrigerator using a single elastic cushioning material. Furthermore, since the elastic cushioning material can be fixed to the mounting body by the elasticity of the elastic engagement claws of the mounting body, the number of parts is reduced compared to the case where multiple elastic cushioning materials are provided or insulation material is provided, making assembly work easier. This has great practical effects, such as a marked improvement in production costs and a reduction in manufacturing costs.
