Claims

[Claims for Utility Model Registration] (1) Joint parts branching radially in the radial direction are integrally formed on a base material having a cylindrical part opened in the longitudinal direction, and the joint parts between these joint parts and the base material are integrally formed. 1. A frame joint structure characterized by integrally forming a bulging part connecting the cylindrical part and bulging radially outward from the cylindrical part. (2) Joint parts branching radially in the radial direction are integrally formed on a base material having a cylindrical part opened in the longitudinal direction, and the joint parts are connected between these joint parts and the base material to form the cylindrical part. What is claimed is: 1. A frame combination structure characterized by integrally forming bulging portions that bulge outward in the radial direction from the shaped portions, and forming an air guide port by cutting out a portion of these bulging portions.
