It is characterized in that it is composed of a reinforcing body that reinforces this, and a seat body that is provided at the lower portion of the reinforcing body so as to be height-adjustable and that is grounded to the ground surface and separates the wheel from the ground surface.

When the height of the seat is adjusted and separated from the ground contact surface, the wheel is grounded to the ground contact surface. Then, the tent frame can be moved to any place on the ground surface by the wheel.
After the tent frame is moved to an arbitrary position, the height of the seat body is adjusted to ground it on the ground surface, and the wheel is separated from the ground surface. Then, the tent frame is supported by the seat having a larger ground contact area than the wheels. For this reason, stable installation is performed, and the weight of the tent frame does not act due to the wheel being released, so that there is no possibility that the wheel is damaged.
Since the reinforcing body is provided side by side with the support, the support is strengthened by the reinforcing body, and there is no possibility that the support is distorted or bent due to a strong wind or the like.
Since the seat body is provided by using the reinforcing body, a dedicated mounting member can be omitted and a sufficient installation space that does not interfere with the wheels can be secured.

  It is preferable that the wheel is provided so that the height of the wheel can be adjusted. In this way, even if the ground contact surface is inclined, the height of the wheel can be adjusted with respect to the support column, and the tent frame can be maintained in an appropriate posture.

  The reinforcing body includes a vertical pipe provided at a predetermined interval in the horizontal direction on the support column, and an appropriate number of connecting plates provided at a predetermined interval in the vertical direction between the support column and the vertical tube. In addition, it is preferable that a seat is provided at the lower portion of the vertical pipe. In this way, not only can the struts be reinforced by the reinforcing body, but also the vertical tube can be used as a seat receiving part. In addition, the longitudinal pipe and the connecting plate of the reinforcing body can be used as a ladder.

  It is preferable that a plurality of reinforcing bodies and seat bodies are provided around the support column. In this way, the presence of multiple seats increases the ground contact area and improves stability, and the reinforcement and seats are located around the support column, so there are multiple reinforcements and seats. The struts and wheels can be physically protected.

According to the present invention, the following excellent effects can be achieved.
(1) Consists of a roof body, struts, wheels, reinforcing bodies, and a seat body, and in particular, a reinforcing body that is arranged in parallel with the struts and reinforces it, and is provided at the lower part of the reinforcing body so that the height can be adjusted.
