1. A pelvis fixing device comprising:
a rear fixing module configured to enclose a side surface and a rear surface of a waist of a user, the rear fixing module including a driving module mounting portion configured to support a driving module mounted thereto, a first rigid frame and a second rigid frame configured to be connected to the rear fixing module, the first rigid frame and the second rigid frame extending in different directions from the rear fixing module;
a front fixing module configured to enclose a front surface of the waist of the user, the front fixing module including a soft layer and a hard layer, the hard layer configured to connect to the rear fixing module such that closed loops are formed around the waist of the user, the hard layer being rigid in a vertical direction relative to the waist of the user and flexible in a back-and-forth direction relative to the waist of the user, the soft layer including a first soft band and a second soft band each having a first side and a second side, the first side of the first soft band being directly attached to the first rigid frame, the first side of the second soft band being directly attached to the second rigid frame; and
a band fastening portion configured to attach the second side of the first soft band to the second side of the second soft band,
wherein the soft layer extends from the rear fixing module,
wherein the hard layer includes a fixing plate at the soft layer, a first unidirectional flexible plate and a second unidirectional flexible plate, the fixing plate including a first length adjusting portion and second first length adjusting portion to adjust a fastening length of the first unidirectional flexible plate and the second unidirectional flexible plate, respectively,
wherein a first side of the first unidirectional flexible plate is configured to be connected to the first rigid frame, and a second side of the first unidirectional flexible plate is configured to be connected to the first length adjusting portion,
wherein a first side of the second unidirectional flexible plate is configured to be connected to the second rigid frame, and a second side of the second unidirectional flexible plate is configured to be connected to the second length adjusting portion,
wherein the first soft band and the second soft band overlap each other in the back-and-forth direction relative to the waist of the user, and
wherein the first unidirectional flexible plate and the second unidirectional flexible plate overlap each other in the back-and-forth direction relative to the waist of the user.
 
12. A motion assistance apparatus comprising:
