    • PROBLEM TO BE SOLVED: To solve the following problem: an adhesion structure having good heat resistance and durability is required since a silicone adhesive has a problem of adhesion failure caused by the deactivation of a platinum catalyst although the silicone adhesive is used so as to solve a problem of durability in which although an epoxy adhesive having heat resistance and high adhesion shear strength is used for the adhesion of a permanent magnet of an electric power steering motor, the adhesion shear strength is reduced by the residual stress generated between the permanent magnet and a metal component or by environmental deterioration (caused by heat, humidity or the like), and thereby, the permanent magnet is peeled and the steering becomes impossible.
      SOLUTION: The method for managing the adhesion shear strength of an adhesion part in a silicone-based adhesion structure is characterized by measuring the amounts of nitrogen, sulfur and phosphorus elements in an adhesion surface, then presetting an approximate function by using a relationship between the adhesion shear strength and the amounts of the elements, and determining whether the adhesion shear strength in the adhesion part corresponding to the measured amounts of the elements is good or not.
