To provide a slide bearing capable of molding a slide surface at low cost and with high accuracy, a bearing unit using the slide bearing, and a motor using the bearing unit.SOLUTION: A slide bearing comprises a cylindrical resin body part, and a thin-walled cylindrical metal auxiliary body that is inserted into an inner diameter part of the resin body part and has an inner diameter surface of a hole as a slide surface. The metal auxiliary body part is composed of a coil spring wound in a spiral manner. It is fixed to the resin body pat in a state of being pressed against a core pin fitted into the metal auxiliary body.SELECTED DRAWING: Figure 1 【課題】すべり面を低コストにて高精度に成形することができるすべり軸受、このすべり軸受を用いた軸受ユニット、及びこの軸受ユニットを用いたモータを提供する。【解決手段】円筒形状の樹脂製本体部と、この樹脂製本体部の内径部にインサートされて孔部の内径面がすべり面となる薄肉円筒形状の金属製副体部とを備えたすべり軸受である。金属製副体部が、螺旋状に巻回したコイルスプリングからなる。金属製副体部に嵌挿されるコアピンに押し付けられた状態で樹脂製本体部に固定されている。【選択図】図１
