<P>PROBLEM TO BE SOLVED: To improve a catching performance in a revolving door. <P>SOLUTION: A first shock absorber 18 extending in a backward direction of the revolution is mounted on a vertical member 8 mounted on the revolving directional front side of each of doorways 2a, 2b formed in a cylindrical wall body 2. A second shock absorber 20 extending toward the front side of the revolving direction is mounted on a front side protruding part 6d of a door body 4. Extended end parts of the first and second shock absorbers 18, 20 serve as sensor sections 18c, 20c which are leaned to come closer to each other. Highly sensitive first and second obstacle detecting sensors 19, 21 are mounted on the sensors 18c, 20c, respectively. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
