When the steered wheels are driven, there is a problem of the torque steering that the steering is disturbed by the difference in the driving forces between a pair of left and right steered wheels. After hydrogenation, the reaction mixture is decanted, the desired hydrogenation product is removed, and catalyst-rich material which settles at the bottom of the vessel is delivered to a single plate pressure filter fitted with a filter bag 40 of permeable material. The garments having such stretch fabric portions include pants-type garments, bib overall type garments, and coat-type garments and coverall-type garments. The method also includes returning the rotatable member to the first rotational orientation such that the rotatable member is allowed to release, via the gap in the perimeter, the projection of the first component to remove the second component from the first component.
