Catalytic converter (2) includes a catalyst container (10) formed from a tubular blank (10′) and having a catalyst carrier, and a flange member (11) joined to the hollow member. The tubular blank (10′) is subjected to a spinning operation by forming roll or rolls (22A), to form the catalyst container (10) having a desired shape, and the opposed circumferential surfaces of the catalyst container (10) and flange member (11) are forced against each other by the forming roll or rolls (22A) or an array of presser pieces (22B) while the catalyst container and flange member are rotated relatively to each other, so that friction heat is generated for friction-welding the catalyst container and flange member at their joining portions (10b, 11b).

A manufacturing method of a catalyst container includes forming a plate member that is partially different in plate thickness or material by joining material plates that are different in plate thickness or material by welding; bending the plate member that is partially different in plate thickness or material to form a hollow material, wherein the hollow material is formed by bending the plate member and joining opposing sides thereof by welding; and changing a sectional shape of the hollow material by a spinning process.

Apparatus for mounting flexible tires on wheels comprising a vertically movable table lifter, a wheel centering shaft, bead spreading rollers and bead dropping rollers, the table lifter and the bead spreading rollers being provided with annular steps thereon, and means for automatically positioning the table lifter at a height, depending on the size of the wheel carried on the table, at which a predetermined vertical distance is left between the upper edge of the wheel rim and the stepped lower surface of the bead spreading rollers.

While a material pipe and a roller are revolved relative to each other with a predetermined radius, the material pipe and the roller are moved relative to each other in the direction of progress of forming by eccentrically moving the center axis of the material pipe and the revolution axis of the roller relative to each other and simultaneously moving the material pipe and the roller relative to each other in the directions of the axis. During movement in the direction of progress of the forming, an end portion of the material pipe is deflected by controlling the axis-direction moving portion so that the roller is moved relative to the material pipe in the direction of the axis when the circumferential position of the roller, with respect to a circumference of the material pipe, changes from an inner side of the direction of deflection toward an outer side of the direction of deflection. This allows the movement of the roller relative to the material pipe in the direction of the axis to be stopped when the circumferential position of the roller changes from the outer side of the direction of deflection toward the inner side of the direction of deflection.

An air pressure filling system for tires includes a rotary table receiving a plurality of tires arranged in a circle. A rotary distribution joint is placed over the rotary table and is connected to an air source through a pressure control device for controlling an air pressure of the tires at a predetermined pressure. A plurality of air hoses are connected to the rotary distribution joint at one end thereof and are adapted to be connected to the tires by an operator at the other end thereof. The operator simply keeps one place where he is able to connect the hoses to the tires one by one while the tires are transferred on the rotary table, and the tire filled with a predetermined air pressure is returned the operator.
