Next, a method for attaching the integrated fuse 30 to the case body 11 will be described.
First, as shown in FIG. 5, the integrated fuse 30 is inserted in the horizontal direction with respect to the mounting portion 17 in a state where the integrated fuse 30 is vertically set. At that time, by inserting the lower end of the insulating resin portion 32 into the upper cover guide inclined portion 24 of the partition wall 20 and the lower end of the input portion 33 against the upper cover guide inclined portion 27 of the partition wall 21, respectively, Since the body fuse 30 can be naturally guided to an accurate mounting position, the integrated fuse 30 can be smoothly inserted and quickly attached to the accurate position.

  The integrated fuse 30 is attached to the case main body 11 by fitting the partition wall 20 for the output portion projecting from the mounting portion 17 of the case main body 11 into the gap between the output portions 34 of the integral fuse 30. The upper surface 20 a of the partition wall 20 is brought into contact with the lower end of the insulating resin portion 32 located in the gap between the output portions 34.
