Summary:PURPOSE:To prevent breakdown accompanied by drop and shock during handling and enable reliability to be ensured by fixing a buffer member on a surface other than a mounting joint surface at a base side which contacts a target mounting surface and then allowing the surface to protrude slightly from the joint surface. CONSTITUTION:A buffer material 17 is adhere to a seat portion of an opening 16 of a plastic case 15 and then a cap stem portion set 13 is adhered and fixed onto it. A metal base is mounted to the other portion of the opening 16, thus enabling flatness of a mounting surface 18 to be The mounting surface 18 is fixed to a partner mounting ensured. surface with a screw 19 and at that time a buffer member 21 is adhered to a recessed portion 20 which is not in contact directly, and a surface of the member 21 protrudes by several mm from the mounting surface 18 in the sensor signal body state. In this case, the member 17 and the member 21 achieve a sufficient effect even at one location, thus enabling a buffer member to be embedded until a moment immediately before using a vehicle and then preventing breakdown of the detection portion due to collision etc.
