[Problems to be Solved by the Invention] However, in these conventional examples, the cylinder portion of the damper device is manufactured in advance as a separate body from the storage box.
They tended to be expensive in terms of cost. Further, since the cylinder portion of the damper device is separate, it is necessary to attach the cylinder portion to the storage box. Conventionally, as shown in FIG.
02 or other suitable clips, etc., but the number of steps is increased by the amount of the mounting work. As shown in FIG.
The space S1 between the space and the area 03 was also large.

Further, in the above conventional examples, one end of a striated body such as a string is fixed to a piston rod of a damper device, and the other end of the striated body is fixed to a terminal fixing portion opposite to the piston rod. However, a guide member such as a guide roller for changing the direction in which the striated body is disposed is required at an intermediate portion of the striated body. In addition to the extra need for the guide member itself, fixed parts such as screw bolts and nuts for attaching the guide member to predetermined positions are separately required.

In order for the piston rod and the guide member not to interfere with each other, a considerable space is required. Therefore, there is a problem that the capacity space of the storage box such as the glove box is reduced by that much in order to secure the fixed parts and the interference prevention space.

Further, there is a problem that extra man-hours are required for assembling the vehicle or for assembling the damper device for attaching the guide member and its fixed parts. SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure of a damper device for a storage box such as a glove box which can effectively solve the problems of the conventional damper device.
