PROBLEM TO BE SOLVED: To solve a problem in which it is hard to reset a position and angle in a conventional sensor unit.SOLUTION: A sensor unit has: a sensor body 21 detecting movements of a human by radio signal a U-shaped sensor holding part 22 where an emission port 21a of the radio signal of the sensor body becomes an opening surface and a base part 11 rotatably holding the sensor holding part 22. The base part 11 has: a plurality of positioning holes 12a to 12d provided on the surface and a ball joint reception part 13 provided in the way that it protrudes from the surface. The sensor holding part 22 has: a ball part 23 provided on the surface facing the opening surface and joined to the ball joint reception part 13 and a projection 24 which is provided on the surface orthogonal to the opening surface and is engaged with one of the plurality of positioning holes in the state that the sensor holding part 22 is joined to the base part 11.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】従来のセンサユニットは、位置及び角度の再設定が難しい問題があった。【解決手段】本発明のセンサユニットは、無線信号により人の動きを検出するセンサ本体21と、センサ本体の無線信号の出射口21aが開口面となるコの字型のセンサ保持部22と、センサ保持部22を回動可能に保持するベース部11と、を有し、ベース部11は、表面に設けられた複数の位置決め穴12a~12dと、表面から突出するように設けられるボールジョイント受け部13と、を有し、センサ保持部22は、開口面に対向する面に設けられ、ボールジョイント受け部13に連結されるボール部23と、開口面に直交する面に設けられ、センサ保持部22をベース部11に連結させた状態で複数の位置決め穴のいずれか1つに嵌る凸部24と、を有する。【選択図】図1
