Abstract: A part fastening structure according to the present embodiment is a part fastening structure that fastens a part by using a bolt and a nut. The bolt is provided on a peripheral surface of a shaft portion, and includes a recess portion recessed to a central axis side and a thread groove provided on a head portion side of the recess portion. The nut includes a first nut member that is screwed into the thread groove, and a second nut member that is disposed on an outer peripheral side of the first nut member. The first nut member is provided with a lever that rotates around a rotation shaft extending in a direction parallel to an axial direction of the bolt.

Abstract: A cupsole, that a user wears and is fixed to a foot sole plate of a walking assistance apparatus that assists a motion of a leg part of the user, includes: a main body part on which the user's foot is placed; and an index member that is fixed to the main body part and is configured to determine an attachment position with respect to a reference index provided in the foot sole plate, the attachment position varying for each user, in which the index member can be attached to or detached from the main body part.

Abstract: A maintenance system includes: a walking training apparatus including a walking assistance apparatus attached to a leg of a trainee, and to assist the trainee in walking, and first transmission means for transmitting information in which information about the number of times of walking or a time of walking performed in the walking assistance apparatus is associated with a component of the walking assistance apparatus; and a server including determination means for comparing the information about the number of times of the walking or the time of the walking transmitted from the first transmission means with a preset evaluation value for durability of the walking assistance apparatus, and determining a timing for performing maintenance for the walking assistance apparatus, and second transmission means for transmitting maintenance information including the timing of the maintenance determined by the determination means and information about the associated component of the walking assistance apparatus.

Abstract: A brace includes a first member, a second member, a joint mechanism, and an insertion-fitting member configured to be insertion-fitted into the joint mechanism in such a manner that the insertion-fitting member can be fixed to and removed from the joint mechanism; the joint mechanism includes an insertion-fitting receiving part, the insertion-fitting receiving part being configured to enable the insertion-fitting member to be insertion-fitted into the joint mechanism, and a regulation part being disposed around the rotation axis in the second member; and the regulation part, which rotates around the rotation axis in an integrated manner with a rotation of the second member, comes into contact with the insertion-fitting member fixed to the insertion-fitting receiving part on a trajectory of the rotation of the regulation part, so that a range of the rotation of the second member is regulated.

Abstract: A joint regulating apparatus configured to regulate a movable range of a joint connecting a first bone part of a wearer with a second bone part of the wearer, includes a first member attached to a part of a body located on a side of the first bone, a second member attached to a part of the body located on a side of the second bone, and a joint mechanism configured to support the first and second members so that the first and second members can swing with respect to each other along a movable direction of the joint in a predetermined regulated swing range, in which the joint mechanism includes an elastic mechanism configured to, when the first and second members tend to swing with respect to each other beyond the swing range, exert an elastic force against the swing.

Abstract: A load detecting device includes a sole shape portion that is formed along a shape of a sole of a walk trainee, and on which the sole gets, a flare portion that is formed so as to project outside the sole shape portion, a first load sensor that is provided at the sole shape portion and detects the load of the sole shape portion, and a second load sensor that is provided at the flare portion and detects the load of the flare portion.

Abstract: A walk training apparatus includes a walking assist device, a first tensile portion, and a second tensile portion.
