A heat exchanger has a core case, at least one fin case disposed in the core case, and pair of upper and lower fins disposed in the fin case. The fin case has an inlet part, an outlet part, and a middle part disposed between the inlet and outlet parts. Each of the upper and lower fins has top and bottom portions. The upper and lower fins are disposed within the fin case so that the upper and lower fins are not in contact with each other at the inlet and outlet parts of the fin case and so that the bottom portions of the upper fin are in contact with respective ones of the top portions of the lower fin at the middle part of the fin case.

An apparatus compresses a mat against a cylindrical catalyst to provide an exhaust gas cleaning device having the catalyst and the mat wrapped around the catalyst. The apparatus has a base to which first and second rods are movably mounted, and first and second pressers connected to respective ones of the first and second rods. A first drive mechanism moves the first, but not the second, rods to bring the first pressers into contact with first peripheral surface portions of the mat so that second peripheral surface portions of the mat are formed into respective convex portions. A second drive mechanism moves the second rods to bring the second pressers into contact with the convex portions of the mat to compress the convex portions while the first pressers are maintained in pressure contact with the first peripheral surface portions of the mat.

A method of manufacturing a wire harness with nipped connectors uses a work table having connector holding tools and wiring/nipping tools in a predetermined pattern thereon and a robot with a hand which can be freely moved on the work table. The hand can selectively hold at least a connector holding head for loading connectors in the connector holding tools and a wiring/nipping head for performing wiring between the connectors to prepare a wire harness.
