Cup holder with flexible protruding portion

摘要

A cup holder for holding and retaining a cup includes a container integrally formed of a resin material as one structure with flexibility. The container includes a bottom portion, a cup retaining portion defined as a sidewall upstanding from the bottom portion, and at least one flexible protruding portion formed in the sidewall where the bottom portion does not contact. The flexible protruding portion is thinner in thickness than other portion of the side wall and protrudes towards an inside direction of the cup retaining portion. A rib is formed on an outside surface of the container to extend from the other portion of the side wall formed thicker than the protruding portion to a center of the protruding portion. An urging device is formed for pressing the protruding portion towards an inside of the container.
