A lubricant supply member of a linear guide includes a first recessed part formed above a guide rail, a pair of second recessed parts formed at both left and right side-surface positions of the guide rail, and protrusions slidable on rail side raceway surfaces of the guide rail. A lubricating unit includes a first cylindrical part, arranged in the first recessed part, to allow the first recessed part to move in a vertical direction of the slider, and to press the first recessed part to a widthwise outside of the slider, and a pair of second cylindrical parts, arranged in the pair of second recessed parts, to allow the pair of second recessed parts to move in a width direction of the slider, and to press the pair of second recessed parts in the vertical direction of the slider, respectively.

In this motion guide device (10), a track member (20) has a recess or protrusion (51) that is formed in a longitudinal direction, and a moving member (30) has a holding protrusion or holding recess (53) that corresponds to the recess or protrusion (51) formed in the track member (20). When force is applied in a direction that would cause relative separation of the moving member (30) and the track member (20), the holding protrusion or holding recess (53) holds onto the recess or protrusion (51) such that the moving member (30) and the track member (20) are unable to be separated. With this configuration, a motion guide device that is both compact and capable of withstanding a strong external load can be obtained.

A steering shaft for a motor vehicle includes a hollow shaft and an inner shaft which is arranged coaxially in the hollow shaft. The inner shaft is configured to be telescoped relative to the hollow shaft in the direction of the longitudinal axis of the steering shaft and is connected in a torque-transmitting manner to the hollow shaft via at least one rolling body. The rolling body is received in a rolling body cage such that it can roll in the direction of the longitudinal axis between the inner shaft and the hollow shaft. In order to achieve a high operational reliability with a relatively low manufacturing complexity, the rolling body cage has at least one seal element which bears sealingly against the hollow shaft and/or the inner shaft.

Closure system for connecting two contiguous transport units in a convoy for the transport of goods, the closure system comprising an accordion-shaped element configured to change the length thereof along a longitudinal axis of the convoy and comprising a central portion and a pair of outer portions placed on opposite sides with respect to said axis, the thickness of the accordion-shaped element decreasing from the central portion to the outer portions.

A low dust linear module includes a rail unit, a slide seat unit, a dustproof strip and two magnetic members. The two magnetic members are disposed at the two slide seat end portions of the slide seat, the first magnetic attraction gap is defined between the magnetic attraction area and a corresponding one of the magnetic members, and the second magnetic attraction gap is defined between the magnetic attraction area and the slide seat cover. When the dustproof strip passes through and are magnetically attracted by the magnetic members, a gap will appear between the magnetic members and the slide seat and the slide seat cover, so that the magnetic members and the dustproof strip are kept in a gap without friction, so as to avoid the generation of dust due to friction, so that the linear module can operate normally and maintain the standard of the working environment.

To provide a linear guide device having a higher dustproof performance and a dustproof function with a higher degree of freedom. A linear guide device includes a guide rail, a slider, and a rolling element, a seal member which seals a gap formed between a side surface portion of the guide rail and an inner side surface portion of the slider. The seal member includes a first seal member provided at the inner side surface portion of the slider, and a second seal member which is larger in width than the first seal member and is provided in a bottom surface portion of a slider body to be independently detachable from the bottom surface portion, as superimposed on the first seal member.

A press-fitting jig for a closure cap which is configured to press-fit a closure cap into a bolt mounting hole formed in a track rail of a guide device. The press-fitting jig is mounted to a moving block, which is assembled to the track rail through intermediation of a plurality of rolling elements and is configured to move on the track rail. The press-fitting jig includes: a finishing surface which is brought into slide contact with an upper surface of the track rail having the bolt mounting hole opened therein; and a guide surface, which is formed adjacent to the finishing surface and forms a wedge-shaped space with the track rail in a longitudinal direction of the track rail, the guide surface being configured to push the closure cap temporarily placed in the bolt mounting hole into the bolt mounting hole along with movement of the moving block.
