In the present embodiment, as shown in the figure, a substantially trapezoidal contact portion 21 having a predetermined height H is provided at the center of a rectangular substrate 10. This height H is the same as the height of the tips of the end portions 12 and 12.
A fixing portion 22 is erected at one end portion of the contact portion 21. A fixing piece 23 projects from the end of the fixing portion 22 toward the outside of the substrate 10 (right side in FIG. 2). Further, a long hole 24 into which the fixing portion 52 of another cover body 3 connected to the substrate 10 can be inserted is formed on the opposite side of the fixing portion 23 of the abutting portion 21. A step portion 25 which is an engaging portion for engaging the fixing piece 53 of the fixing portion 52 with the opening portion is configured.

  Both end portions 12 of the substrate 10 are curved inward (abutting portion side) to form a chain accommodating portion 15, and a protruding portion 13 and a recessed portion 14 are formed on the end surface of the end portion 12, respectively. Part. At the time of connection, the projection 43 of the other substrate 40 is inserted into the recess 14. The connecting portion is not limited to this configuration, and other shapes of protrusions and recesses may be employed. Furthermore, if there is no problem in strength, a configuration such as applying an adhesive to a smooth surface may be used.

The chain retracting portion 11 provided at the center between the upper end and the lower end of the substrate 10 is for avoiding interference between the lower end and the upper end of the upper and lower chains 31, 31.
A cover main body 3 having the same shape as the cover main body 2 configured as described above is formed.

Next, the operation of this embodiment will be described.
First, one of the cover main body 2 and the cover main body 3 is rotated 180 degrees so that the chain 31 is accommodated in the accommodating portions 15 of each chain, and the fixing portion 22 of the cover main body 2 is replaced with another cover main body. The fixed piece 23 at the tip is engaged with the step portion 55 so as to be inserted into the third long hole 54 and opened outward.
