Abstract:
Provided is a pillar-equipped valve device that can hinder deformation of a fuel tank, can increase the accuracy of full-tank limiting, and can suppress the flow of fuel into a ventilation chamber. This pillar-equipped valve device 10 has: a valve device body 15 that is attached to a fuel tank 1 having a bottom wall 2 and a top wall 4; and a pillar 70 that extends in a tubular shape. The valve device body 15 has a housing 17, in which a valve chamber, a ventilation chamber, and an opening are provided, and a float valve 60 that is raisably/lowerably accommodated in the valve chamber and blocks the opening 25. The pillar 70 forms a tubular shape that extends from the bottom wall 2 side to the top wall 4 side of the fuel tank 1, and a bottom end section 73 thereof is fixed to the bottom wall 2 and a top end section 75 thereof is directly or indirectly fixed to the top wall 4.
