STRUCTURE FOR FIXING KNUCKLE BRACKET OF HYDRAULIC DAMPER

摘要

PROBLEM TO BE SOLVED: To provide a damper tube unnecessary to increase the rigidity of the damper tube and to simplify a mounting process by preventing a knuckle bracket from a deformation when the knuckle bracket is mounted to the damper tube. SOLUTION: The outer diameter of the lower end portion of a diameter tube 11 is made a stepwise shape constituted of a smaller diameter portion 31 and a larger diameter portion 32 and by strongly squeezing the upper portion of the fixing portion 20A of the knuckle bracket 12 into the larger portion 32 of the lower end portion of the damper tube 11 the lower portion is welded to the damper tube 11.
