PURPOSE: Foldable chairs with rollers are provided to improve the durability of rollers and friction pads by integrating the rollers and the friction pads with frames. CONSTITUTION: A foldable chair with a roller includes a first frame(100), a second frame(200), a first supporting part(110), a second supporting part(120), a friction pad, a first spacing part, and a roller(130). The first frame is rotatably combined with a seating plate. The second frame is rotatably combined with the seating plate and the first frame. The first supporting part supports loads by being formed at the contacting part of the first frame and the ground. The second supporting part supports loads by being formed at the contacting part of the second frame and the ground. The friction pad is mounted at either the first supporting part or the second supporting part. The first spacing part spaces the remaining part of the first supporting part and the second supporting part from the ground. The roller is rotatably combined with the first spacing part. |
