To provide an abnormality diagnosis device for an opening/closing body device capable of informing that an abnormality will occur in the near future before an abnormality occurs in the opening/closing operation of the opening/closing body due to deterioration of the opening/closing body device.SOLUTION: A PU 82 integrates the current flowing through a motor 72 each time a sliding door 20 is driven. The PU 82 determines the degree of deterioration of an upper rail 30, a center rail 40, and a lower rail 50 based on the integrated current. When the PU 82 determines that the degree of deterioration is large enough to cause a perceptible abnormality in the opening/closing of the sliding door 20 in the near future, the PU 82 operates a display device 94 to notify that fact.SELECTED DRAWING: Figure 1 【課題】開閉体装置の劣化に起因して開閉体の開閉動作に異常が生じるのに先立って、近い将来に異常が生じることを知らせることができるようにした開閉体装置の異常診断装置を提供する。【解決手段】ＰＵ８２は、スライドドア２０が駆動される都度、モータ７２を流れる電流を積算する。ＰＵ８２は、積算した電流に基づき、アッパレール３０、センターレール４０およびロアレール５０の劣化の度合いを判定する。ＰＵ８２は、劣化の度合いが、近い将来、スライドドア２０の開閉に感知しうるほどの異常をきたすほど大きいと判定する場合に、表示装置９４を操作してその旨を通知する。【選択図】図１
