Abstract: A fixing force measuring apparatus including a section for applying a predetermined controlled hammering force to a wedge surface to generate a hammering sound, a section for controlling the hammering sound generated, a section for obtaining plural kinds of feature quantities such as a feature quantity due to a hammering sound energy, and a feature quantity due to a frequency of the hammering sound from the hammering sound collected by an arithmetic operation, and a section for obtaining a fixing force corresponding to the plural kinds of feature quantities by using a correlative relationship between the wedge fixing force previously obtained, and the plural kinds of feature quantities.
