Abstract: A pipe extending from a first side toward a second side includes a side wall and a spool. The spool formed in the side wall is bent so as to protrude from an outer circumferential surface of the pipe, and extends to surround the outer circumferential surface. The spool includes a first portion located on the first side and a second portion located on the second side. There is a clearance between the first portion and the second portion in a top region of the spool, and the first portion and the second portion substantially abut each other in a base region.

Abstract: A disposing method for an inlet pipe in a muffler that includes an outer shell, an inlet pipe, and a separating plate, the disposing method comprising: a first step of inserting the inlet pipe into the outer shell from an opening at one end of the outer shell; a second step of disposing the inlet pipe by moving the inlet pipe within the outer shell in a direction substantially orthogonal to the direction of insertion of the inlet pipe; and a third step of disposing the separating plate by inserting the separating plate into the outer shell from the opening at the other end of the outer shell.

Abstract: A side wall of a pipe is clamped by a first die and a second die to thereby clamp the pipe. The first die and the second die are made to approach each other while an end of the pipe is pressed toward the first die by the third die along a longitudinal direction of the pipe, to thereby form a spool between the first die and the second die. In a state where the spool is clamped by the first die and the second die, the third die is separated from the pipe along the longitudinal direction of the pipe so as to separate the second die and the third die from each other. Clamping of the pipe is released such that the first die and the second die separate from the side wall of the pipe, to thereby unclamp the pipe.

Abstract: In a method for manufacturing a burring processed member, an inner-circumferential surface of a plate-like curved portion is pressed in a first direction, thereby forming a side wall and a seating face, the side wall protruding from a rim of a first hole, the seating face extending from a tip of the side wall. In the method, a circular second hole is formed on the seating face, and the burring processed portion protruding in the first direction from the rim of the first hole is formed. The seating face includes two crests, each situated on a periphery of each end of the curved portion in a circumferential direction, and is slanted such that a seating face height becomes smaller from each of the crests to a substantial center in the circumferential direction.

Abstract: A press device includes: a first die having a shape of an elliptical cylinder; a second die having a first recess that forms a part of an elliptical-cylindrical space configured to arrange the first die therein; a third die having a second recess to be combined with the first recess to form the elliptical-cylindrical space; a first press mechanism that inserts the first die along a radial direction of the first die to the first recess of the second die over which the flat metal stock is placed so as to press the metal stock; and a second press mechanism that moves the third die relative to the first die inserted to the first recess so as to confine the first die and the metal stock in the elliptical-cylindrical space formed by the first recess and the second recess.
