The invention provides a passive wearable knee joint load reducing device which comprises a left branch and a right branch, the left branch and the right branch are in mirror symmetry and arranged on the two sides of the lower limb of a user, and each branch comprises a thigh assembly, a knee joint gear pair, a shank assembly, a supporting load reducing assembly and a monitoring assembly. The thigh assembly is meshed with the shank assembly through the knee joint gear pair, the monitoring assembly is connected with the shank assembly through the supporting and load reducing assembly, the knee joint gear pair can simulate the change of the rotation center of the knee joint of a user, and a tension spring of the supporting and load reducing assembly can generate thrust in the shank direction; supporting load-reducing force is transmitted to the thigh through cooperation of all components in the knee joint gear pair, part of load acting on the knee joint by the body weight is counteracted, so that arthralgia and
