  "textContent": "A valve device (20) includes a valve body (4) and a valve seat body (5). The valve seat body (5) has a thick cylindrical shape extending in an axis line direction (Z). The valve seat body (5) includes a seal groove (59) on an outer periphery thereof, the seal groove (59) extending in a circumferential direction. The valve seat body (5) includes a large-diameter portion (51) and a small-diameter portion (52) on an inner periphery thereof, the large-diameter portion (51) and the small-diameter portion (52) being connected to each other in the axis line direction (Z). The valve seat body (5) includes a valve seat portion (54) between the large-diameter portion (51) and the small-diameter portion (52), the valve body (4) being seated on the valve seat portion (54). The position of the seal groove (59) in the axis line direction (Z) coincides with the position of the valve seat portion (54) in the axis line direction (Z) or is located on a high-pressure side of the position of the valve seat portion (54) in the axis line direction (Z).",
