In a non-use state where no beverage container is housed in a housing space, holding claws are urged by a ring spring to an advanced reference position where the holding claws are mostly advanced into the housing space and a bottom plate is urged by a coil spring to a highest reference position where the bottom plate is mostly moved upwardly. When a beverage container is housed in the housing space, the holding claws are pushed toward the radial outer direction of the housing space by the side surface of the beverage container, whereby the holding claws move backwardly against the urging force of the ring spring. Simultaneously, since the weight of the beverage container is applied to the bottom plate, the bottom plate moves downwardly against the urging force of the coil spring, whereby a lock member moves downwardly together with the downward movement of the bottom plate. Thus, since a restricted slanted surface abuts against the lock member, the weight of the beverage container is transmitted to a restricted vertical surface from the lock member, so that the backward movement of the holding claw is restricted.

1. A cup holder comprising: a holder main body which has a bottom portion and has a housing space for housing a beverage container therein;a holding claw which is swingable around a hinge portion as a swingable shaft provided at a lower portion of the holding claw, an upper portion of the holding claw moving into and out of the housing space;a first urging member which urges each of the holding claws to a direction where the holding claw moves forwardly;a bottom plate which is disposed at a lower portion of the housing space so as to be vertically movable;a second urging member which urges the bottom plate to a direction where the bottom plate moves upwardly;a lock member which contacts with and separates from a restricted slanted surface formed on a backward movement side of the holding claw, the lock member restricting the backward movement of the holding claw at a time of abutting against the restricted slanted surface; anda coupling member which transmits a vertical movement of the bottom plate to the lock member, whereinthe restricted slanted surface inclines downwardly on the backward movement side of the holding claw, whereinin a non-use state where no beverage container is housed in the housing space, the holding claws is urged by the first urging member to an advanced reference position where the holding claw is mostly advanced into the housing space, the bottom plate is urged to a highest reference position where the bottom plate is mostly moved upwardly, and the lock member locates at a portion separated from the restricted slanted surface above the restricted slanted surface, and whereinwhen a beverage container is housed in the housing space, the holding claw is pushed by a side surface of the beverage container to thereby move backwardly against an urging force of the first urging member and, simultaneously, the bottom plate moves downwardly against an urging force of the second urging member since a weight of the beverage container is applied to the bottom plate to thereby move the lock member downwardly in an interlocked manner with the downward movement of the bottom plate, whereby since the restricted slanted surface abuts against the lock member, the weight of the beverage container is transmitted to the restricted slanted surface from the lock member to thereby restrict the backward movement of the holding claw. 2. The cup holder according to claim 1, wherein the restricted slanted surface has a stepwise configuration where steep slanted surfaces and gentle slanted surfaces are coupled continuously in an alternative manner, and the backward movement of the holding claw is restricted when the lock member abuts against the restricted slanted surface. 3. The cup holder according to claim 1, wherein a restricted vertical surface having a vertical or substantially vertical surface is formed beneath the backward movement side of the restricted slanted surface, and the abutment inner surface of the lock member locates at a height capable of abutting against the restricted vertical surface of the holding claw urged to the advanced reference position in a state where the lock member is mostly moved downwardly. 4. The cup holder according to claim 1, wherein the first urging member is a ring spring which is formed in a C-shape by subjecting a steel wire to a bending process, and wherein a plurality of holding claws are provided so as to surround the beverage container housed in the housing space from a circumferential direction thereof and the ring spring is assembled so as to surround all the plurality of holding claws from the backward movement side of the holding claws. 5. The cup holder according to claim 1, wherein the first urging member is an elastic rubber ring of an annular shape, and wherein a plurality of holding claws are provided so as to surround the beverage container housed in the housing space from a circumferential direction thereof and the rubber ring is assembled so as to surround all the plurality of holding claws from the backward movement side of the holding claws. 6. The cup holder according to claim 1, wherein a plurality of holding claws are provided so as to surround the beverage container housed in the housing space from a circumferential direction thereof, whereinthe first urging member is a polygonal ring which is formed in a polygonal shape by subjecting a steel wire to a bending process so as to have torsion spring portions which number is same as the holding claws, whereineach of the torsion spring portions is configured by two bent portions each having substantially same height as the hinge portion and disposed respectively on both sides of the hinge portion, two arm portions respectively extending upwardly from the bent portions, and an apex portion for coupling tip ends of the arm portions, whereinthe polygonal ring is formed as a flat plane area, in a plan view, surrounded by the apex portions and lines each for coupling end portions of the adjacent apex portions with a shortest distance, the polygonal ring being assembled with all the holding claws in a manner that the apex portions respectively abut against the backward movement sides of the holding claws, and whereinwhen the apex portion of the torsion spring portion is pushed toward the backward movement side of the holding claw, each of the arm portions swings toward the swinging direction of the holding claw, whereby since each of the arm portions and/or each of the bent portions are twisted, an elastic force for restoring the apex portion is generated at each of the arm portions and/or each of the bent portions on the forward movement direction side of the holding claw. 7. The cup holder according to claim 1, wherein the holding claw is made of resin and the hinge portion of the holding claw is an integral hinge.
