PURPOSE:To provide a pin in two directions for the main body of a bobbin in a securely supported manner by a method wherein the bobbin main body and a pin mount are constituted separately, and an L-shaped pin is supported by an inverted T-shape hole formed on the pin mount. CONSTITUTION:The mounting recess 4 of a pin mount 10 is formed at the upper and the lower ends of the bobbin main body 2, made of synthetic resin, of the transformer whereon a winding is attached to a body part 2a. A pin retaining hole 12 is provided on the mount 10, both ends of the hole 12 are opened on both side faces of the mount 10, and a rising part 14 is formed by having one third part 12a of the hole 12 opened upward from the mount 10. A pin-retaining hole 16 is formed on the rising part 14 in such a manner that the side opposing to the part 12a is opened, and the rising part 14 is formed in inverted T-shape together with the hole 12. After the bottom horizontal part 18a of a pin 18 has been tightly fitted to the hole 12 of said mount 10 and the uprightly erected part 18b has been tightly fitted to the hole 16, thereby the mount 10 is tightly fitted to the recess 4.
