The present invention relates to a heat emitting joint guard including a component for heat emission and vibration, and having a joint structure thereby not imposing strain the movement of wrists or ankles, wherein the heat emitting joint guard having a joint structure, and alleviating pain of joints includes: a battery seating unit on the upper part of which a plate-type battery is seated； a heat emitting unit in a plane shape which is coupled to the bottom part of the battery seating unit； a circuit seating unit on the upper part of which a driving circuit unit is seated； a vibration unit which is coupled to the bottom part of the circuit seating unit； a joint unit which couples the battery seating unit and the circuit seating unit and which becomes biased and expanded； a driving circuit unit including a platy-type battery which supplies energy for driving the heat emitting unit in a plane shape and the vibration unit and is discharged by the driving circuit unit, a discharging circuit to discharge the plate-type battery, a selection switch to select driving of the heat emitting unit in a plane shape and the vibration unit, and a discharging terminal to connect to external power supply for discharge； and a band unit which is a band shape having flexibility, being made with fiber material, and having a certain thickness, and includes an insertion unit where the battery seating unit coupled to the joint unit and the circuit seating unit are inserted. Therefore, the present invention provides a thermal function and massage function, while maintaining the function, use, and applicability of the typical band-type joint guard. Also, the present invention does not impose strain the movement of wrists and ankles due to the joint unit which is twisted and expanded according to the movement of the wrists and ankles. Indeed, the present invention is wearable.본 발명 관절구조를 갖고 관절통증을 완화시키는 발열 관절보호대는 발열과 진동을 위한 구성을 포함하고, 관절구조로 되어 손목 또는 발목의 움직임에 부담을 주지않는 발열 관절보호대에 관한 것으로, 상부면에 판상의 배
