Claims

[Scope of utility model registration request]

A reciprocating rod that can reciprocate in the horizontal direction and is cantilevered by a support member, an actuating member that operates the reciprocating rod, and a reciprocating rod that can reciprocate in a direction perpendicular to the direction of movement thereof due to the reciprocating movement of the reciprocating rod. A displacement member is installed at the upper and lower parts of the reciprocating rod so that they can be separated or approached, and a molded member is detachably attached to the upper and lower parts of the displacement member and has a length that is approximately the same as the length of this displacement member. , an oval tube manufacturing apparatus in which a circular tube inserted between the forming members is formed into an oval tube by pressure caused by the separation of the displacement members, wherein the forming members have two stages having different heights in the longitudinal direction; An apparatus for manufacturing an oval pipe, characterized in that it has the above molded part on its outward facing surface.
