A hydraulic buffer device includes a first cylinder that stores oil, a rod member capable of being moved with respect to the first cylinder as being inserted into the first cylinder toward a first side of the first cylinder and being protruded outward from the first cylinder on a second side of the first cylinder, a rod guide that covers the second side of the first cylinder as having a through-hole, an oil seal arranged at the outer side of the rod member in the radial direction on the second side of the first cylinder, a groove portion that forms a flow path for oil flowing from the inside of the first cylinder toward the oil seal, and a small-diameter portion that restricts flow of oil flowing through the groove portion. An appropriate amount of fluid is supplied to a seal member in a pressure buffer device.
