One end of the pole body is installed on the rotary shaft. A weight (18) is installed in a place opposed to a place for installing the pole body of the rotary shaft. A locking means (20) is further provided for locking the pole body in the box in a substantially horizontal state. When releasing locking by the locking means, the pole body rotates around the rotary shaft by the action of the weight, and is constituted so as to be brought into a substantially upright state. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
