Transformer

A transformer (101) comprising:

• a coil pressing metal fitting (303, 401, 501, 601) that presses against a coil (403, 503, 603) from an outside, the coil (403, 503, 603) being wound around an iron core leg (402, 502, 602) made of an amorphous ribbon,
• wherein the coil pressing metal fitting (303, 401, 501, 601) includes a coil pressing metal fitting base member (201, 301) that comes into contact with the coil (403, 503, 603), and a reinforcement member (302) disposed outside the coil pressing metal fitting base member (201, 301),
• the coil pressing metal fitting base member (201, 301) has a hole (202, 204) at a predetermined location,
• the reinforcement member (302) is connected and fixed to the coil pressing metal fitting base member (201, 301) by a joining member from inside the coil pressing metal fitting base member (201, 301) through the hole (202, 204) of the coil pressing metal fitting base member (201, 301),
• wherein the coil pressing metal fitting base member (201, 301) includes stepped portions (304) provided at a top and a bottom of the coil pressing metal fitting base member (201, 301), and a flat portion (305) provided between the stepped portions (304) at the top and the bottom,
• the hole (202, 204) of the coil pressing metal fitting base member (201, 301) includes positioning holes (204) provided in the stepped portions (304) and a connection hole (202) provided in the flat portion (305),
• the reinforcement member (302) includes engaging portions (306) provided at a top and a bottom of the reinforcement member (302), and
• in a state where the engaging portions (306) of the reinforcement member (302) are inserted and positioned in the respective stepped portions (304) of the coil pressing metal fitting base member (201, 301) through the positioning holes (204), the connection hole (202) of the coil pressing metal fitting base member (201, 301) is connected by a connecting member from inside the coil pressing metal fitting base member (201, 301).
