In the present invention, the patient to be moved to the destination lying on the stretcher to feel comfortable. For this purpose, the structure of the stretcher is to be changed as follows to solve the anxiety factors such as shock and movement generated during the movement of the stretcher. That is, when the caster wheel ③ of the stretcher rolls on the floor surface such as the road surface while the patient moves the stretcher to the destination, the shock generated by passing the obstacle between the floor surface and the caster wheel ③ must be absorbed. However, because of the structural problems of the conventional caster wheel ③ can not absorb the shock, the shock is transmitted to the patient. In this design, the present invention replaces the cushion caster wheel (FIG. 1) and installs it as an advantage of the buffer caster wheel (FIG. 1), and solves the problem by absorbing the shock, and the seat ① size of the stretcher. However, since it is generally matched to an adult's body size, it is a lot of inconvenience for a patient of a small size such as a child. On the other hand, the seat ① of the existing stretcher is not detachably fixed to the stretcher, so that it can be easily replaced with a small seat suitable for children (Fig. 4), and the seat (Fig. 3, 4) When connecting, use the spring ④ instead of bolt type to absorb the shock transmitted to the frame, and standardize the spring hole ④ on the frame ② to make it easier to replace the seat (Figs. 3 and 4). Therefore, the seat (Figs. 3 and 4) can be easily replaced, and the existing stretcher has a fixing belt ⑥ which fixes the body of the transfer patient to the stretcher frame ② so that the patient's body is firmly tied to the stretcher. If there is a lot of space between the patient's body and the stretcher, if the patient struggles or the vehicle rattles, the patient's body moves a lot on the stretcher, causing pain and injury. The wife may get worse. On the other hand, the fixing belt 6 is attac
