An elevator buffer has: a base cylinder; a plurality of plungers; and a plurality of forcing bodies. The base cylinder has: a base portion; and a cylinder portion that is disposed on the base portion. A hydraulic fluid is kept inside the cylinder portion. The plurality of plungers are coupled sequentially so as to be slidable upward from the cylinder portion. The respective plungers are vertically displaceable separately relative to the cylinder portion while being subjected to resistance from the hydraulic fluid. The plurality of forcing bodies, which separately force the respective plungers upward away from the base portion, are disposed side by side on the base portion.
