Beschreibung
Zusammenfassung:	An electric prosthetic leg includes a below-knee member, an above-knee member, a knee joint mechanism coupling the below-knee member and the above-knee member such that angles formed between the below-knee member and the above-knee member are variable, and an expansion-contraction device capable of varying the angles formed between the below-knee member and the above-knee member by expanding and contracting, in which one side of the expansion-contraction device in an extending direction is mechanically connected to the below-knee member, and the other side of the expansion-contraction device is mechanically connected to the above-knee member. Assuming that smaller one of minimum formed angles, of the angles formed between the below-knee member and the above-knee member centering on a pivoting portion of the knee joint mechanism, is defined as a second formed angle, the expansion-contraction device is partially disposed on a side of a first formed angle.
