ATMOSPHERIC VENT STRUCTURE FOR REDUCING AGENT TANK

摘要

An atmospheric vent structure for a reducing agent tank, configured so that the front end of an atmospheric vent hose is reliably prevented from being closed by the deposition of the reducing agent or foreign matter. The structure is obtained using a simple configuration without routing the atmospheric vent hose from the reducing agent tank to a vehicle frame or without providing an additional part, such as a dust cover, to the front end of the atmospheric vent hose. An atmospheric vent structure for a reducing agent tank, having an atmospheric vent hose (25) which is connected to a reducing agent tank (11) mounted to the vehicle frame (13) through a bracket (12). A cover section (16) which covers at least a part of an outer side surface of the reducing agent tank (11) is formed on the bracket (12). The atmospheric vent hose (25) is routed between the outer side surface of the reducing agent tank (11) and the cover section (16) of the bracket (12). The front end (26) of the atmospheric vent hose (25) is disposed at a position which is located between the outer side surface of the reducing agent tank (11) and the cover section (16) of the bracket (12) and at which the front end (26) of the atmospheric vent hose (25) is covered with the cover section (16) and is not exposed to the outside. The reducing agent tank (11) is affixed to the cover section (16).
