Abstract: The change in a contact over time is stabilized by lowering intense wear of the contact in the initial sliding stage and imparting stabilized wear characteristics from the initial sliding stage. The contacts (33, 34) of a sliding body (30) have flat tops which contact conductive segments (23) and come into surface contact with the top portions of the conductive segments (23) when the contacts slidingly contact onto the conductive segments (23).

Abstract: A freezing apparatus comprises a cooling hollow body to receive food products to be frozen thereon and to be driven for rotation, a flexible container made of a flexible sheet material which is arranged on the upper surface of the cooling hollow body so as to cover said products placed on said upper surface, a cold brine circulating path including the hollow portion of the cooling hollow body and the interior of the flexible container which are mutually communicated to feed cold brine, a plurality of adapters attached to the outer periphery of the flexible container, and a guide rail provided around the outer periphery of the flexible container to slidably support the adapters. The flexible container is moved synchronousely with the cooling hollow body due to a frictional force resulted between the flexible container and the cooling hollow body.
