The main body 3 or the drawer body 1 is urged so as to protrude forward of the case 2 using force as power.

(Functional Features) The above cup holder has the following advantages over the conventional structure.
(1) First, the main body 3 or the drawer body 1 resists the urging force of the winding spring 9 by engaging the pin 7a of the swing member 7 with a locking recess (not shown) provided in the cam groove 35. The case 2 is locked in the storage position. That is, the cup holder is engaged at the storage position where the main body 3 or the drawer body 1 is pushed into the case 2 against the urging force of the winding spring 9 by the push / push locking mechanism including the cam groove 35 and the pin 7a. Then, when the main body 3 or the drawer body 1 is pushed in the pushing direction and the hand is released, the locking is released and the main body 3 or the drawer body 1 is moved forward to the extraction position by the urging force of the winding spring 9. At the pulled-out position, the lower holding member 15 is in a use state in which it is inclined downward by a predetermined angle with the shaft portion 19 as a fulcrum, and the bottom surface of the container C inserted into the main body hole portion 1a can be received and supported by the tray 17.

(2) In addition to the above basic operation, in this structure, the light emitting area of the illumination molded body 4 has a circular portion 40 (inclined portion 41) corresponding to the hole 1a, and a long piece portion 43 disposed on the side surface of the main body. The short piece 45 is disposed in front of the main body and exposed to the opening 11. Therefore, even when the passenger compartment is dark, the occupant can securely put in and out the container 1 such as a beverage into the hole 1a that is brightened by emitting light from the circular portion 40, and the light of the circular portion 40 passes through the upper ring portion 32. Since the tray 17 side is also illuminated through the hole 33a of the upper surface 33, the entire position can be easily seen even when the container C is held, and both side surfaces and the front surface of the drawer 1 are exposed to the long piece 43 and the opening 11. Since the short piece portion 45 emits light and the outline of the drawer body 1 can be understood, this is excellent in that there is no possibility of accidentally colliding with the drawer body 1.

  Note that the present invention is not limited to the above-described embodiment, and it is only necessary to substantially include the configuration specified in the claims, and details can be variously changed as necessary. As a specific example, the structure in which the transparent cover 5 also has a portion covering the short piece portion 45, the illumination molded body 4 is turned on in conjunction with the drawer body 1 being pulled out from the case 2, and the drawer body 1 is turned on. Is automatically turned off in conjunction with being housed in the case 2 and turned off, the drawer 1 or the main body 3 is replaced with a hole to form a recess for a container, that is, the housing is changed to a similar device.
