PRESSURE SENSITIVE SENSOR

PROBLEM TO BE SOLVED: To prevent the separation of protector rubber by arranging a series of through holes in an overlapping part of sensor main body-attached protector rubber and a metallic bracket, and inserting and fixing a plastic rivet. SOLUTION: For example, a nip preventive pressure sensitive sensor is formed into a mode of fixing protector rubber 1 enclosing a pressure sensitive sensor main body 4 to a metallic bracket 2 by using a plastic rivet 3 composed of an adhesive and a thermoplatic resin such as ABS. For example, a series of through holes 5 are arranged in a part of two places positioned on both sides of an overlapping part of an arm 11 of the protector rubber 1 and the side edge 21 of the metallic bracket 2, the plastic rivet 3 is inserted, and the arm 11 and the side edge 21 are superposed and fixed by forming a head part 31 on both ends of the plastic rivet 3 by heat molding. An outside diameter of a bar before molding the plastic rivet 3 is set to 1 to 3 mm, and an outside diameter of the head part 31 after molding is desirably set to 5 to 8 mm.
