PURPOSE: To obtain a resin hollow body with reduced likelihood of generating cracks in the connection places of resin divided bodies in a resin hollow body comprising the step of connecting a pair of resin divided bodies. CONSTITUTION: Resin divided bodies 2, 3 having projections 8, 11 with through holes 10, 13 formed therein are allowed to be in abutment relation at their connection parts 4, 5, and the outer peripheral surfaces 14, 15 and projections 8, 11 of the connection parts 4, 5 are welded together by injection molding via a resin connection material 6 so as to join both the resin divided bodies 2, 3. At that time, a summit part 18, arm part 19, and charged part 20 are formed integrally, thereby firmly connecting both the resin divided bodies 2, 3. |
