Patent number: 10201436Abstract: A present invention provides a joint power control device. A joint interlock displacement part (52) of a power transmission movable mechanism (53), which is comprising of a moving pulley (51) and the like, is connected to a joint mechanism (5) disposed between a first member (2) and a second member (3). A flexible lengthy member (32), which is one of two flexible lengthy members (32, 32) extending from the power transmission movable mechanism (53), is connected to a control mechanism (54) that controls the movement of the flexible lengthy member (32). Further, an elastic structure (31) is engaged with the other flexible lengthy member (32).Type: GrantFiled: December 22, 2015Date of Patent: February 12, 2019Assignee: Honda Motor Co., Ltd.Inventors: Yosuke Ikedo, Toru Takenaka, Hiroshi Gomi, Yoshinao Sodeyama, Kenichi Katagiri
