To provide a hose connection coupler which prevents a breakage of vehicle equipment even if a dirt drawing out hose cannot be detached from a dirt tank.SOLUTION: A hose connection coupler connecting a dirt drawing hose to a dirt tank when a dirt is drawn from a dirt tank of a railway vehicle, has a tubular shape, comprises a body part which has one end part connected to a discharge valve installed in the dirt tank and another end part connected to the dirt drawing hose and an engagement part which restrains detaching of the body part from the discharge valve in a condition the body part is connected to the discharge valve and releases a state connecting the body part to the discharge valve by a breakage or a deformation of a part of the engagement part caused by a prescribed force less than a breakage force of the dirt drawing hose when the body part is loaded with a force to detach the body part from the discharge valve in a condition the body part is connected to the discharge valve.SELECTED DRAWING: Figure 7

    【課題】汚物抜き取り用ホースが汚物タンクから取り外されなかった場合でも車両設備の破損を防止できるホース接続用カプラーを提供する。【解決手段】鉄道車両の汚物タンクから汚物を抜き取る際に、汚物抜き取り用ホースを汚物タンクに接続するためのホース接続用カプラーであって、管形状を有し、一方部が汚物タンクに設けられた排出バルブに接続され、他方部が汚物抜き取り用ホースに接続される本体部と、本体部を排出バルブに接続した状態で、排出バルブからの本体部の離脱を規制する係合部とを備え、本体部を排出バルブに接続した状態で、本体部に対して排出バルブから引き離す方向の力が加えられた場合、汚物抜き取り用ホースが破断する力未満の所定の力で係合部の一部が破断または変形することにより、本体部と排出バルブとの接続状態を解除する、ホース接続用カプラー。【選択図】図7
