Abstract: A surface treating holder includes a wire which is coiled at distances in such a manner that it is formed as a spring-like tubular structure having spiral-line faces at opposite ends thereof, so that works are accommodated in the tubular structure. A process for surface-treating a pluarlity of works accommodates the works in the holder, and surface treating the works in the holder while being rotated about an axis of the works.

Abstract: A surface-treating support member for supporting a plurality of works, including an upper cage and a lower cage including a plurality of compartments, so that the cages are openable and closeable in a lengthwise direction. A process for surface-treating a plurality of works rotates the works about their axes using the support member.

Abstract: In a process for surface-treating a plurality of works, the surfaces of the works are treated in a treating chamber, while being rotated about their axes, or about a rotational axis, or about their axes and about the rotational axis. The works are supported in a support member which may be comprised of an upper cage and a lower cage including a large number of compartments, so that the cages are openable and closable in a lengthwise direction. The support member may be comprised of plate-like elements openably and closably foldable in a lengthwise direction, so that a plurality of narrow sections each having a length corresponding to an inside diameter of a work are defined in opened states of the plate-like elements. The works may be supported in a holder which is formed by coiling a wire at distances in such a manner that it is formed as a spring-like tubular structure, so that the works can be accommodated in the tubular structure.

Abstract: A process for surface-treating a plurality of works which includes the step of surface-treating the works in a treating chamber, while rotating the works about their axes in spaced apart states, wherein the surface treatment is a vapor deposition on a sintered article and the support member includes plate-like elements openably and closably foldable in a lengthwise direction, the plate-like elements defining a plurality of narrow sections each having a length in opened states corresponding to an inside diameter of a work. The support member may also include an upper cage and a lower cage which are openable and closable in a lengthwise direction.
