An auxiliary supporting device generally comprises a head pad section, a backrest, section, a hip section and a joint set. The insert of the head pad section can be inserted into the receiving hole of the backrest section such that the projected section of the head pad section is biased against to the front section of the backrest section. The moveable latch of the backrest section can be inserted into the moveable latch hole of the rolling rod. And then a pair of positioning latches can be inserted into the positioning latch holes such that the relative position between the supporting arm of the bottom bracket and the rolling rod can be attained. The clamp of the retaining block of the hip pad section can be engaged with the retaining beam of the backrest section. By this arrangement, a foldable auxiliary sporting device is attained.
