To provide a cover device for a wiring duct, the cover device having low deflection, providing light operation of rotatably opening/closing a duct aperture even though a wiring cover has high rigidity, and being capable of suppressing generation of sound of collision, on an article of furniture or utensil comprising a wiring duct, such as a desk, table, or bench.SOLUTION: A cover device for a wiring duct is configured by providing wiring covers 5 so as to be capable of being rotatably opened/closed to a duct aperture 4 provided at an appropriate position of an article of furniture or utensil. Base end parts of the wiring covers are vertically rotatably supported by shaft support parts 7 on at least two bearing tools 6 arranged inside the duct aperture. A stroke type damper 8 is vertically supported in the vicinity of a shaft support part of the bearing tool. An operation pin 9 having a hemispherical contact part 22 at an upper end part thereof is disposed upwardly. Thereby, the operation pin comes into contact with a reception surface 10 of a wiring cover to elastically energize the wiring cover in an opening direction until the wiring cover is in a horizontal state after the cover is in a state of being inclined by a predetermined angle.SELECTED DRAWING: Figure 5 【課題】デスクやテーブル、あるいはベンチ等の配線ダクトを備えた家具や什器において、撓みが少なく、剛性が高い配線カバーであってもダクト開口部を回動開閉する操作が軽く、また衝突音の発生を抑制することが可能な配線ダクトのカバー装置を提供する。【解決手段】家具や什器の適所に設けたダクト開口部４に、回動開閉可能に配線カバー５を設けてなる配線ダクトのカバー装置であって、ダクト開口部内に配置した少なくとも二つの支承具６に配線カバーの基端部を軸支部７にて上下回動可能に支持するとともに、支承具の軸支部の近傍位置にストローク式ダンパー８を上下方向に支持し且つ上端部に半球状の当接部２２を備えた作動ピン９を上向きに配置して、配線カバーが所定角度の傾斜状態から水平状態に至るまで作動ピンが配線カバーの受面１０に当接して、配線カバーを開く方向へ弾性付勢する。【選択図】 図５
