Zusammenfassung:To provide a position detector for suppressing damage.SOLUTION: A position detector includes: a detection unit that outputs a signal according to the change in the position of a detection target; sensors 31 and 32 having resin portions 314 and 324 covering the detection unit; and a cover 60 that is formed of a resin having a coefficient of linear expansion different from the coefficient of linear expansion of the resin portions 314 and 324 and covers a part of the resin portions 314 and 324 so that the resin portions 314 and 324 protrude. The resin portions 314 and 324 include a protruding surface and side surfaces 412 and 415; the cover 60 has a covering surface 630, inclined surfaces 632 and 635 connected to the covering surface 630 and the side surfaces 412 and 415, and a convex portion projecting in the projecting direction of the resin portions 314 and 324; the convex portions are connected to the side surfaces 412, 415 and the inclined surfaces 632, 635.SELECTED DRAWING: Figure 4 【課題】破損を抑制する位置検出装置を提供する。【解決手段】位置検出装置は、検出対象の位置の変化に応じた信号を出力する検出部と、検出部を覆う樹脂部314、324とを有するセンサ31、32と、樹脂部314、324の線膨張係数とは異なる線膨張係数の樹脂で形成されており、樹脂部314、324が突出するように樹脂部314、324の一部を覆うカバー60と、を備え、樹脂部314、324は、突出面と、側面412、415とを含み、カバー60は、被覆面630と、被覆面630と側面412、415とに接続されている傾斜面632、635と、樹脂部314、324の突出方向に突出する凸部とを有し、凸部は、側面412、415と、傾斜面632、635とに接続されている。【選択図】図4
