The joist end cover 72 is attached to the left and right end faces of the joist 2 by inserting the mounting portions 72b, 72b into the spaces s3, s3.

(Effects of the deck of this embodiment)
In the deck of this embodiment, end support members 5 are fixed across multiple joists 2, 2 to support the protruding portions of the deck material, so that the deck material 3 can be stably supported while being arranged to protrude from the joists 2, thereby improving strength.
The deck material that protrudes from the end of the joist has its end (connecting part) hooked onto the deck locking piece of the end fixing fitting of the end support member and fixed, so the deck material can be reliably supported.

In this embodiment of the deck, the side edges of the deck material 3 extend beyond the ends of the joists 2. This prevents the ends of the joists 2 from protruding beyond the side edges of the deck material 3, preventing injuries caused by hitting the legs against the joists when sitting on the deck, and also provides a deck with excellent design.

In addition, the end support members 5 are fixed to the joists 2 by brackets 51 placed inside the hollow portions of the joists 2. This means that the weight of the deck material 3 attached to the end support members 5 can be supported not only by the end faces of the joists 2 but also by the joists 2 themselves, further increasing the support strength of the deck material 3.

It goes without saying that the above embodiments do not limit the invention described in the claims, but are to be treated as examples.
