PROBLEM TO BE SOLVED: To prevent an outer wall from falling down by prividing a rib which connects between the outer wall of a tape drawing opening side in the backward section of a moving passage for a slide door and an inner wall facing the outer wall. SOLUTION: An outer wall 34 provided with a tape drawing opening 2 and a nearly circular inner wall 35 facing the outer wall 34 are independently raised from the edge part of a bottom wall 36, and a moving passage 37 for a slide door 3 and a backward space being its extending part are formed between the outer wall 34 and the inner wall 35. A hole 23 allowing the insertion of a sporting shaft tip end part when the slide door 3 is opened is formed in a wall part 21 provided in the back side of the moving passage 37 for the slide door 3, and a rib 40 which connects between the tape drawing opening 2 side outer wall 3 and the inner wall 35 is integrally formed in the just back side of the moving passage 37 for the slide door 3. Falling down of the outer wall 34 is prevented when upper and lower halves are injection molded by connecting between the tape drawing opening side outer wall 34 and the inner wall 35 facing the outer wall 34 with the rib 40.
