[Problem] The purpose of the present invention is to provide a leg supporter which can support the gastrocnemius muscle from front to back and from side to side, without disturbing the movements of the Achilles tendon, and prevent excessive vibration of the gastrocnemius muscle to thereby reduce the wearers fatigue. The leg supporter comprises: a first anchor section (2) for tightening the wearers below-knee part with a tubular knitted fabric a second anchor section (3) for tightening the wearers above-ankle part with the tubular knitted fabric and a gastrocnemius muscle-supporting section (4) which is a roughly X-shaped knitted fabric intersecting in the neighborhood of a point facing the joint (102a) of the gastrocnemius muscle (101) and the Achilles tendon (102) in the back face side of the tubular knitted fabric, two ends of said roughly X-shaped knitted fabric being joined to the first anchor section (2) respectively to support the gastrocnemius muscle (101) while the remaining two ends of said roughly X-shaped knitted fabric being joined to the second anchor section (3) respectively and extending along the both sides of the Achilles tendon.La présente invention concerne un support de jambe qui peut supporter les muscles jumeaux de lavant vers larrière et dun côté à lautre sans affecter les mouvements du tendon dAchille, et éviter les vibrations excessives des muscles jumeaux, ce qui réduit la fatigue du porteur. Le support de jambe comprend : une première section dancrage (2) permettant de serrer la partie sous le genou du porteur avec un tissu tricoté tubulaire une deuxième section dancrage (3) permettant de serrer la partie au-dessus de la cheville du porteur avec le tissu tricoté tubulaire et une section de support des muscles jumeaux (4) qui est un tissu tricoté ressemblant à un X dont lintersection est à proximité dun point correspondant à la jonction (102a) entre les muscles jumeaux (101) et le tendon dAchille (102) du côté de la face arrière du tissu
