It has the lintel part 34a (refer FIG. 1) penetrated.

Next, the characteristic operation and effect of the opening / closing device 1 having the above configuration will be described in detail.
First, as shown in FIG. 1, in the fully closed state in which the closing direction end portion of the opening / closing body 10 is brought into contact with the seating target site p, the thickness adjusting means 16 is wound in the case portion 34 of the storage portion 30. It is pulled out from 31 and located on the guide shaft 32 side.
For this reason, it is possible to prevent the thickness adjusting means 16 from being exposed to the lower side of the storage portion 30 and impairing the appearance of the design, and the outer diameter of the opening / closing body 10 remaining on the winding body 31 is reduced. It is kept relatively small.
Further, in this fully closed state, the fastening part (detachment means 13) between the suspension base sheet 11 and the main body sheet 12 is sandwiched between the extra winding portions of the winding body 31, so that the load or impact applied to the opening and closing body 10; It is possible to prevent the fastening portion from being detached due to wind pressure or the like.

  When the opening / closing body 10 is opened and wound around the winding body 31, the body sheet 12 is wound around the winding body 31 in the width direction of the body sheet 12. The engaging / disengaging members 15 on both ends are wound up, but the thickness adjusting means 16 is also wound up near the center in the width direction of the opening / closing body 10, so that the portion near the center in the width direction of the opening / closing body 10 in the main body sheet 12 has its own weight. The opening / closing body 10 wound around the winding body 31 can be prevented from causing an eccentric winding thickness or coming into contact with the case portion 34, and thus the size of the case portion 34 in the vertical direction can be reduced. Is possible.

Further, when the opening / closing body 10 is wound around the winding body 31, the main body sheet 12 is wound around the outer periphery of the thickness adjusting means 16, but the main body sheet 12 is wrapped around the rubber flexible thick member 16b. Since the sheet 12 is not directly wound and the anti-stain cover 16c is interposed between the sheets 12, foreign matter (for example, dirt or surface deteriorated material) of the flexible thick member 16b is transferred to the main body sheet 12. Can be prevented.
Further, the dirt prevention cover 16c has a non-fixed portion 16c2 that is longer in the opening / closing body opening direction than the flexible thick member 16b and is not fixed to the flexible thick member 16b at the center in the longitudinal direction. Therefore, when the thickness adjusting means 16 is wound around the winding body 31, the bending of the flexible thick member 16b is impaired, the outer diameter shape becomes distorted, and excessive tension acts on the dirt prevention cover 16c. It is also possible to prevent the occurrence of damage or peeling.

Further, when the opening / closing body 10 is damaged due to contact with an obstacle or the like and is replaced, as shown in FIG. 4, if the opening / closing body 10 is forcibly pulled out from the winding body 31, The connection part (detachment means 13) between the suspension side sheet 11 and the main body sheet 12 in the opening / closing body 10 can be exposed, and the main body sheet 12 can be easily detached by peeling off from the suspension side sheet 11.
Further, when the new main body sheet 12 is connected to the suspension side sheet 11, both the markings 11 b and 12 a 1 are aligned in the width direction, and the main body sheet 12 is overlapped and pressed against the suspension side sheet 11. Thus, both of these sheets can be easily connected.

  Moreover, since the suspension side sheet | seat 11 is inserted and latched in the latching recessed part 31b1 opened in the tangential direction of the winding body 31 outer periphery, the force of the opening / closing body thickness direction acts on the latching part. It is possible to prevent the suspension side sheet 11 from being damaged or detached.

  According to the opening / closing device 1, the engagement / disengagement member 15 is provided via the rod member 14 at a position away from the end portion in the width direction of the main body sheet 12.
