A torque limiter unit (6) comprising a first metal member (lining plate (62)) and second metal members (pressure plate (63), cover plate (64)) pressed on to the first metal member by using a prescribed force, and configured such that the first metal member and the second metal members slide relative to each other against the friction occurring between the first metal member and the second metal members. In addition, a first coating layer (622) comprising a compound including a 3d transition metal is formed on a sliding surface of the first metal member and second coating layers (632, 642) comprising a compound including a 3d transition metal are formed on a sliding surface of the second metal members. Selon l'invention, une unité de limiteur de couple (6) comprend un premier élément métallique (une plaque de revêtement (62)) et des seconds éléments métalliques (une plaque de pression (63), une plaque de recouvrement (64) pressés sur le premier élément métallique à l'aide d'une force prescrite, et configurés de telle sorte que le premier élément métallique et les seconds éléments métalliques coulissent les uns par rapport aux autres contre la friction qui se produit entre le premier élément métallique et les seconds éléments métalliques. De plus, une première couche de revêtement (622) comprenant un composé comportant un métal de transition en 3d est formée sur une surface coulissante du premier élément métallique et des secondes couches de revêtement (632, 642) comprenant un composé comportant un métal de transition 3d sont formées sur une surface coulissante des seconds éléments métalliques. 　トルクリミッタ部６は、第１金属部材（ライニングプレート６２）及び第１金属部材に所定の圧力でもって押し付けられた第２金属部材（プレッシャプレート６３、カバープレート６４）を備え、第１金属部材と第２金属部材との間に生じる摩擦力に抗して第１金属部材と第２金属部材が相対的に摺動するよう構成される。また、第１金属部材の摺動面に３ｄ遷移金属を含む化合物により構成された第１被膜層６２２が形成され、第２金属部材の摺動面に３ｄ遷移金属を含む化合物により構成された第２被膜層６３２，６４２が形成される。
