The motion guide device clamper mechanism includes a clamper main body connected to the movable member, an inner face having a tapered shape so that the distance between the facing faces is narrower toward the end of one face of the track member, and one rolling member disposed between the facing faces of the one face of the track member and the inner face. The rolling member receives a pressing force toward a position where the distance between the facing faces of one face of the track member and the inner face of the clamper main body is narrow, so that a frictional force based on the taper shape acts on the rolling member, and the restraint of the clamper main body with respect to the track member is performed. Further, a frictional force based upon the taper shape is released and the non-restraint of the clamper is performed.

This rotation ring includes an inner ring with a first rolling element travel groove, an outer ring with a second rolling element travel groove that faces the first rolling element travel groove, and a plurality of rolling elements interposed between the first rolling element travel groove and the second rolling element travel groove. The plurality of rolling elements include a plurality of hard rolling elements disposed at intervals in the circumferential direction, and a plurality of soft rolling elements, at least three or more of which are disposed between the hard rolling elements adjacent to each other in the circumferential direction and which are lower in rigidity than the hard rolling elements.

A seat moving/securing deviceincludes a long reference memberextending in a longitudinal direction of a seat installation surface and securely installed, a leg part attachment memberhaving securely installed therein a leg part of a seat, a linear guideattached between the long reference memberand the leg part attachment memberand enabling the leg part attachment memberto move horizontally along a longitudinal direction of the long reference member, and a locking mechanismsecurely installed on the leg part attachment member. A coil springserving as an elastic body exhibiting a pressing force is installed between the leg part attachment memberand the linear guide. Due to having this type of configuration, the seat moving/securing devicecan move and secure a seateasily and quickly.

Slide rail

Provided is a moving unit capable of easily mounting and dismounting a movable body to and from track rails. The moving unit includes the pair of track rails, which are laid on a fixed portion at an interval therebetween, and respectively have guiding surfaces on surfaces opposed to each other, a plurality of moving blocks, which are accommodated and arranged in an accommodating space sandwiched between the pair of track rails, and are configured to travel on the guiding surfaces of the respective track rails, and the movable body, which is arranged so as to be opposed to the fixed portion across the accommodating space, and is retained by the moving blocks. The movable body includes a mounting and dismounting mechanism, which is configured to change the interval between the moving block to be assembled to one of the track rails and the moving block to be assembled to another one of the track rails to cancel a contact state between the moving blocks and the respective track rails. The mounting and dismounting mechanism is accommodated together with the moving blocks in the accommodating space.
