PROBLEM TO BE SOLVED: To reduce the number of components as much as possible to enable stable molding of a projection part shape, and to avoid interference with a bearing ring to provide a relatively rotatable shape.SOLUTION: A bearing device 10 includes a rolling bearing where a plurality of rolling bodies 103 is disposed between an inner ring 101 and an outer ring 102, and a fixation plate 11 having a circular hole part 13 fitted to the outer peripheral surface of the outer ring 102 of the rolling bearing to fix the rolling bearing to a housing. An engaging groove 109 is formed in the outer peripheral part of the outer ring 102, and in the inner peripheral part of the fixation plate 11, an engaging part 16 projecting on radial inside is formed with press punching. 【課題】部品点数は上記同様極限まで抑え、突起部形状の安定成形且つ軌道輪との干渉を避け相対回転可能な形状を提供する。【解決手段】軸受装置１０は、内輪１０１と外輪１０２との間に複数の転動体１０３が配設された転がり軸受と、該転がり軸受をハウジングに固定すべく、前記転がり軸受の外輪１０２の外周面に嵌合される円形穴部１３を有する固定プレート１１と、を備える。外輪１０２の外周部には、係止溝１０９が形成され、固定プレート１１の内周部には、径方向内側に突出する係止部１６がプレス打ち抜き工程を用いて成形される。【選択図】図１
