OBSTACLE DETECTOR FOR BUILDING SHUTTER

摘要

PROBLEM TO BE SOLVED: To improve the reliability of an obstacle detection by vertically moving an obstacle detection member formed in the bottom face of a seat plate without tilting in the indoor outside direction in whatever part the obstacle detection member abuts on an obstacle. SOLUTION: This shutter which is so formed that the obstacle detection member formed in the bottom face of the seat plate of a shutter curtain stops the lowering of the shutter curtain by receiving the upward movement by the abutment of the obstacle, is integrally provided with a slide piece in the longitudinal end face of the obstacle detection member, while it is formed with a guide part vertically supporting the slide piece in the seat plate end face.
