2. Description of the Related Art Conventionally, as an opening / closing body safety device of this type, for example, as disclosed in Japanese Utility Model Laid-Open No. 5-71397, an obstacle detection sensor for detecting an obstacle at a lower end portion of an overdoor is used. This obstacle detection sensor is composed of a transmitter that is contracted by an obstacle and detects an obstacle by a change in internal air pressure, and a pressure switch that detects a pressure change in the transmitter and converts it into an electric signal. When the transmitter comes into contact with an obstacle and is pressed while the overdoor is descending, the transmitter contracts, the pressure change inside is detected by the pressure switch, and converted into an electric signal. A configuration is known in which the output is output to a lift drive motor, the operation of the drive motor is stopped, and the lowering of the overdoor is stopped.

In the structure described in the above publication, the obstacle detection sensor detects these as obstacles when they come into contact with a person or an object while the overdoor is descending, and also the floor of the opening. In order to detect this floor surface as an obstacle even when it comes into contact with the surface, that is, the obstacle detection sensor detects the obstacle and stops the overdoor at the lower limit position of the lowering, and the lower end portion of the overdoor and the floor surface. Since it also serves as a gap between the openings, the transmitter of the obstacle detection sensor is pressed on the floor surface every time this opening is opened and closed, and it is flattened in the vertical direction. The transmitter's restoration stroke becomes smaller because of the habit of deforming the condition, and the transmitter's restoration stroke cannot absorb the gradient at the site where there is a slope on the floor surface. A gap is formed between the lower end and the floor surface of the emitter, can not be sufficiently close the opening, there is a problem that.
