PROBLEM TO BE SOLVED: To see that a suction panel does not open easily even if a child plays it though a grown-up person can open and close it easily. SOLUTION: A safety protective means 60 is made of a slide hole 61 in slot form which is made at the opening and closing lever 42 of a lock means, a handle whose shank is inserted into the slide hole 61, and a regulating part 63 which is arranged on the rear side of the suction panel in the position corresponding to the slide hole 61 so as to fix the handle 62. Then, this is so arranged that the regulating part 653 juts out of the opening/closing lever 42 and projects to the end of the suction panel to regulate the operation of the opening/closing lever 42, by operating the handle 62 in the direction of the slot of the slide hole 61. |
