To provide a detention brake gear and a detention brake system capable of preventing dragging of a vehicle in an unreleasable state after connection.SOLUTION: A detention brake gear 11 and a detention brake system 10 comprise: a detention brake cylinder 20 that is provided in a trailer 3 of a freight train 1 and that outputs a detection brake force of a detection brake for retaining the trailer 3 to a brake lever 32 for braking wheels of the trailer 3 by means of a brake spring 24, and cancels a pressing force of the brake spring 24 by a piston 22 when compressed air is supplied; and a selector valve 13 that supplies, when the trailer 3 is connected to a connection vehicle 4 constituting the freight train 1, the compressed air of an air storage pipe 5 drawn from the connection vehicle 4 to the detention brake cylinder 20 to cancel the pressing force of the brake spring 24 by the piston 22, and releases the detection brake.SELECTED DRAWING: Figure 1

    【課題】連結後に不緩解状態での車両の引きずりを防止する留置ブレーキ装置及び留置ブレーキシステムを提供する。【解決手段】留置ブレーキ装置11及び留置ブレーキシステム10は、貨物列車1の付随車3に設けられ、付随車3を留置させる留置ブレーキの留置ブレーキ力をブレーキばね24によって付随車3の車輪を制動するブレーキ梃子32に出力するとともに、圧縮空気が供給されるとブレーキばね24の押付力をピストン22が打ち消す留置ブレーキシリンダ20と、付随車3が貨物列車1を構成する連結車4と連結されると、連結車4から引き通される空気溜め管5の圧縮空気を留置ブレーキシリンダ20に供給してピストン22がブレーキばね24の押付力を打ち消し、留置ブレーキを緩解させる切替弁13と、を備える。【選択図】図1
