PROBLEM TO BE SOLVED: To prevent disconnection of a cable connected to a body motion detection circuit.SOLUTION: For a body motion detector, on the side of a bottom surface 10a of a housing 10 suspended from a part to be attached such as a headboard of a bed through a hook 30, a cable 20 connected to the body motion detection circuit inside the housing 10 is fixed by a prescribed fixing means. In the body motion detector, a hook locking part 17 for locking the proximal end part 30a of the hook 30 is provided on the side of the back surface 10b of the housing 10, a projection 18 is provided on the distal end of the hook locking part 17, a recess 31 to be fitted as a pair with the projection 18 of the hook locking part 17 is provided on the proximal end part 30a of the hook 30, and by locking the projection 18 and the recess 31, the hook 30 is attached to the housing 10.COPYRIGHT: (C)2013,JPO&INPIT【課題】体動検出回路に接続されるケーブルの断線を防止する。【解決手段】ベッドのヘッドボードなどの被取付部にフック30を介して吊り下げられる筐体10に底面10a側に、筐体10内の体動検出回路に接続されるケーブル20が所定の固定手段により固定されている体動検出装置において、筐体10の裏面10b側にフック30の基端部30aを係止するフック係止部17を設け、フック係止部17の先端に凸部18を設けるとともに、フック30の基端部30aにフック係止部17の凸部18と雌雄嵌合する凹部31を設け、それら凸部18と凹部31とを係止させることにより、フック30を筐体10に取り付けた。【選択図】図2
