A seal chain includes two inner link plates opposed to and spaced apart from each other, a tubular bushing, opposite ends of the bushing being respectively joined to the two inner link plates, a pin rotationally inserted into the bushing, a tubular roller into which the bushing is inserted, the roller being rotationally supported by the bushing, and two outer link plates arranged to externally hold the two inner link plates in between, opposite ends of the pin being respectively joined to the two outer link plates. A recess into which an end of the roller is inserted is formed in an inner surface of each of the inner link plates.

Seal chain

A chain includes two inner link plates, cylindrical bushings, each of which has opposite ends joined to the inner link plates, pins each inserted into a bushing, solid lubricant provided between the bushings and the pins, and two outer link plates that sandwich the inner link plates from outside. The ends of the pins extend through the outer link plates. The chain further includes projections, which maintain the distances between the outer surfaces of the inner link plates and the inner surfaces of the outer link plates, and absorbent members, which are arranged between the outer surfaces of the inner link plates and the inner surfaces of the outer link plates. The absorbent members confine the solid lubricant and are capable of absorbing liquid.

Chain

A portable optical reader is provided with: a reading partoptically reading a symbol as a reading object; a head partstoring the reading partand having a reading portfor the reading part; a holding partcontinuously connected to the head partand extending in a connecting direction; and a display partprovided in the head partand displaying at least a reading result. The head partis formed by side surfaces, and the display partis provided in at least two side surfaces which are a side surface facing to a surface providing the holding part, and a side surface in which a reading direction by the reading partand an extending direction of the holding partare substantially orthogonal to each other.

Portable optical reader

A bearing roller chain includes a tubular bush configured to interconnect link plates facing each other, a tubular metal-made roller through which the bush is inserted, a plurality of metal-made anti-friction rollers arranged between an inner circumferential surface of the roller and an outer circumferential surface of the bush, and annular nonmetallic restraint members fitted into openings at the opposite ends of the roller in an axial direction, with the bush inserted through the restraint members, the restraint members configured to restrain axial direction movement of the plurality of anti-friction rollers.
