PROBLEM TO BE SOLVED: To provide a hydraulic buffer the structure of which can be simplified and the cost of which can be reduced.SOLUTION: A hydraulic buffer 1 according to the present invention comprises: an outer tube 2 and an inner tube 3 fitted together so as to be able to slide on each other; a rod 7 one end of which is bound in the outer tube 2 and another end of which is inserted into the inner tube 3; and a piston part 8 bound to an end part of the rod 7 that faces the inside of the inner tube 3. Working fluid (air and oil) is enclosed in the outer tube 2 and the inner tube 3, and a gap between the inner tube 3 and end parts (spring joints 12 and 13) of the piston part 8 is formed so as to be smaller than a gap between the inner tube 3 and a region (a spring collar 9) other than the end parts of the piston part 8. |
