Abstract: A buffer device providing reliable buffer effect includes a channel-shaped buffer member and at least one first reinforcing tubular member. The channel-shaped buffer member is a substantially U-sectioned hollow member and includes two facing inner sidewalls, two opposing outer sidewalls, an inner bottom wall, two outer top walls and an outer bottom wall to enclose a third buffer space therein. The first reinforcing tubular member is received in the third buffer space and encloses a first buffer space therein. The first reinforcing tubular member includes at least one normal-direction supporting wall extended between and pressed against the inner and outer bottom walls and provided with at least one second curved buffer section. The normal-direction supporting wall and the second curved buffer section thereof not only give the channel-shaped buffer member an increased normal-direction supporting strength, but also buffer impact force and compressing force applied normal to the outer bottom wall.
