Claims

[Scope of utility model registration request]

An elevating opening/closing body that opens and closes the opening is electrically driven to move up and down, and a pressure sensor that converts pressure changes into electrical changes is provided over approximately the entire length of the lower edge of the elevating opening/closing body. A safety device for a lifting opening/closing body that controls a driving means of the lifting opening/closing body based on electrical changes caused by pressure changes,
The pressure-sensitive sensor is a safety device for the lifting/lowering opening/closing body, which is arranged so as to extend from the bottom surface of the lower end frame of the lifting opening/closing body to the rear side.
