Patent ID: 7520405

Claim:
A cup holder, comprising: a holder body having an accommodation portion into which a container is fitted; an inner-peripheral-side supporting member disposed rotatably within the accommodation portion of the holder body, and having a first rotary shaft-center, a base end, an inner-peripheral-side supporting portion, and a leading end, the base end being supported pivotally so as to be rotatable about the first rotary shaft-center, the inner-peripheral-side supporting portion being capable of supporting a minor-diameter container when contacting with a side face of the minor-diameter container, the leading end being provided with the inner-peripheral-side supporting portion; a first urging member for urging the inner-peripheral-side supporting member rotatably upward to a first datum position, at which the inner-peripheral-side supporting portion of the inner-peripheral-side supporting member protrudes by a first predetermined magnitude within the accommodation portion of the holder body, in such a direction that the inner-peripheral-side supporting member protrudes within the accommodation portion; an outer-peripheral-side supporting member disposed rotatably within the accommodation portion of the holder body, and having a second rotary shaft-center, a base end, an outer-peripheral-side supporting portion, and a leading end, the base end being supported pivotally so as to be rotatable about the second rotary shaft-center, the outer-peripheral-side supporting portion being capable of supporting an intermediate-diameter container, whose diameter is larger that of the minor-diameter container, when contacting with a side face of the intermediate-diameter container, the leading end being provided with the outer-peripheral-side supporting portion; and a second urging member for urging the outer-peripheral-side supporting member rotatably upward to a second datum position, at which the outer-peripheral-side supporting portion of the outer-peripheral-side supporting member protrudes by a second predetermined magnitude within the accommodation portion of the holder body, in such a direction that the outer-peripheral-side supporting member protrudes within the accommodation portion; the first rotary shaft-center of the inner-peripheral-side supporting member, which is located at the first datum position, being disposed at a position, which is displaced by a predetermined magnitude toward an imaginary center of the accommodation portion of the holder body with respect to the second rotary shaft-center of the outer-peripheral-side supporting member, which is located at the second datum position.
