A work vehicle includes an electric motor including a flange on a first side in an axial direction, a vehicle body including a plate having the electric motor fixed thereto, and an extension connecting the flange and the plate and including a boss portion, and a flange portion extending radially outward from an axial end of the boss portion. The plate is located on a first side of the flange in the axial direction. The boss portion is fixed to the flange by a first bolt in a through hole in the plate from a first side in the axial direction and fastened to the flange from the first side in the axial direction. The flange portion is fixed to the plate by a second bolt on the first side of the plate in the axial direction and fastened to the plate from the first side in the axial direction.

A fuel cell is described that uses a movable overpressure prevention unit to automatically narrow the fluid flow path when internal pressure exceeds a safe limit. The system includes a cell stack for power generation, a fluid supply unit, and conduits directing air, hydrogen, or coolant to the stack. An overpressure prevention member is biased by an elastic element so it remains out of the flow under normal conditions. At higher pressure, it moves into the path, limiting the cross-sectional area and lowering pressure. A variant employs an extension bracket between separate conduits, replacing a standard hose bracket while integrating the same protective mechanism. Additionally, a method is disclosed in which an extension bracket with an overpressure prevention member helps prevent damage to components by automatically engaging when fluid pressure surpasses a set threshold.
