Abstract: A housing is made sealable even when the rigidity of a frame member and a cover member is not high. In an EFEM, a pressure difference having a predetermined value or less exists between an internal space of a housing and an external space of the housing. The housing includes a frame member assembled so as to form an opening, a cover member attached to the frame member so as to cover the opening, and a seal member sandwiched between the frame member and the cover member and configured to extend so as to surround the opening. The frame member and the cover member are formed of a sheet metal. The seal member is an elastic member having a hollow cross section orthogonal to an extension direction of the seal member.

Abstract: A non-contact power supply device is used in a processing apparatus including a moving unit movable inside a closed container. The device supplies electric power to the moving unit from outside the closed container. The power supply device includes a feed unit and a heat dissipater. The feed unit includes a feed line and a power supply transformer. The feed line has a feed region arranged inside the closed container along the moving direction of the moving unit. The transformer is arranged inside the closed container so as to be opposed to the feed region in a non-contact manner and is provided so as to move together with the moving unit. The heat dissipater includes a portion on one end side connected to the feed region so as to be capable of conducting heat thereto, and a portion on the other end side extending outside the closed container, so that heat generated in the feed region is partially dissipated outside the closed container.
