• the top prop according to the present invention is composed of two bodies having different diameters.
• a lower body 20 having a larger diameter forms a lower part of the top prop, and an upper body 30 having a relatively smaller diameter forms an upper part of the top prop.
• the upper body 30 is received into the lower body 20 as in an antenna.
• a lower housing 50, to which the folding frames 4 are connected, is fixedly attached to a lower end of the lower body 20.
• An upper housing, to which the folding frames 4 are connected is slidably attached to an upper part of the lower body 20 such that it can slide along the lower body 20.
• a support cap 10 having a larger diameter than that of the lower body 20 is fixedly attached to an upper end of the upper body 30.
• the structure for controlling the height of the roof of the folding tent includes the lower body 20 and the upper body 30, which form the top prop, the lower housing 50, which is fixedly attached to the lower end of the lower body 20, a spiral coil spring 40, which is inserted into the lower body 20, and a control cap 60 which is rotatably coupled to a bottom surface of the lower housing 50.
• the lower housing 50 is fixedly attached to the lower end of the lower body 20 and thus moves together with the lower body 20.
• the folding frames 4 are rotatably hinge-connected to the lower housing 50 in all directions. Therefore, if the folding frames 4 rotate, the lower housing 50 moves up/down together with the lower body 20.
• the coil spring 40 which is inserted into the lower body 20, is an elastic spring formed of a spiral steel wire and elastically supports the upper body 30.
• the upper body 30, which forms an upper part of the top prop, is received into the lower body 20 as in an antenna. Therefore, when the folding tent is set up or folded, the upper body 30 slides upward or downward along the inside of the lower body 20.
• the coil spring 40 inserted into the lower body 20 is also received into the upper body 30.
• a plurality of guide protrusions 32 inserted between the steel wire of the coil spring 40 protrude from inner side surfaces of the upper body 30. Therefore, if the coil spring 40 or the upper body 30 is rotated, the guide protrusions 32 moves upward or downward along the steel wire of the coil spring 40. Consequently, the upper body 30 moves upward or downward according to the movement of the guide protrusions 32.
• the control cap 60 is used to rotate the coil spring 40 and is rotatably coupled to the bottom surface of the lower housing 50.
• the control cap 60 includes a handle 62 at a lower end thereof and a concave accommodating groove 64, into which a lower tip end of the coil spring 40 is inserted, at an upper end thereof.
• a penetrating aperture 52 may be formed on the bottom surface of the lower housing 50 so that the control cap 60 can be coupled to the bottom surface of the lower housing 50.
• the handle 62 of the control cap 60 is rotated to the left or right, the coil spring 40 whose lower tip end is accommodated in the accommodating groove 64 of the control cap 60 is also rotated to the left or right. Accordingly, the upper body 30 moves upward or downward.
• the upper and lower bodies 30 and 20 may be polygonal, not round.
• the accommodating groove 64 has closed side surfaces and an open top surface.
• the lower tip end of the coil spring 40 can be freely accommodated in or removed from the accommodating groove 64 through the top surface of the accommodating groove 64.
• the upper body 30 moves downward. Accordingly, the coil spring 40 moves downward.
• the lower tip end of the coil spring 40 is naturally accommodated in the accommodating groove 64 through the top surface of the ac- commodating groove 64.
• the upper body 30 moves upward. Accordingly, the coil spring 40 moves upward. Then, the lower tip end of the coil spring 40 is naturally removed from the accommodating groove 64 through the top surface of the accommodating groove 64.
• the coil spring 40 is not naturally removed from the accommodating groove 64 but fixed to the accommodating groove 64, it has to remain stretched for a long time. Consequently, the elasticity of the coil spring 40 may be reduced.

• the accommodating groove 72 has closed side surfaces and an open top surface.
• the accommodating groove 72 is fixed to the bottom surface of the lower housing 70, it cannot directly rotate the coil spring 40. Therefore, the upper body 30 is rotated upward or downward. In other words, if the upper body 30 is rotated to the left or right, a plurality of guide protrusions 32 of the upper body 30 move along a steel wire of the coil spring 40. Accordingly, the upper body 30 can be move upward or downward. In order to be rotated as described above, the upper body 30 may be round in the present embodiment. However, if a diameter of the upper body 30 is sufficiently smaller than that of the lower body 20, it can rotate even if the upper body 30 is polygonal.
