PURPOSE:To provide the structure for preventing loose-out of a connecting pin, which connects a front and a rear bodies divided from one body, easily at a low cost. CONSTITUTION:A front body 9A and a rear body 9B are separately structured, and a body frame 5A of the front body 9A and a body frame 5B of the rear body 9B are formed so as to be inserted to each other, and a loose-out preventing connecting pin 16 is inserted to an insert junction part from the upper for fitting to join the front body 9A and the rear body 9B. An elastic mat 18 is placed on the insert junction part of the front body 9A and the rear body 9B, and a part of this elastic mat 18 over the connecting pin 16 can be tuned over, or the connecting pin 16 is fitted under a turnable part of the elastic mat 18, which can be turned over. |
