Abstract

PURPOSE: To prevent reduction of pressure on the fastened surface of a laminated core by fastening a fastening strip wound on the core via a spring member having about the same spring contact as that of the core.
CONSTITUTION: A fastening strip 2 such as a glass tape or steel band is wound on a laminated core 1 of a transformer or the like, and a spring member 8 having about the same spring constant as that of the core 1 is coupled to one end of the fastening strip 2. With this arrangement, the shrinkage of the laminated core 1 due to drying thereof at the time of the manufacture of secular "decay" is absorbed by the spring member 8, so that it is possible to prevent reduction of the fastening pressure for the integration of the core due to reductin of the core fastening force with shrinkage of the core 1.
