In a monotube type hydraulic shock absorber, a plurality of rectangular recesses that are elongate in a circumferential direction are formed in an outer circumferential surface of a cylinder at a position in the vicinity of an upper limit of a slidable range of a free piston. A support for supporting an external part such as a sensor or a hose is positioned so as to be fitted around a portion of the cylinder at which the recesses are formed. Thereafter, while supporting the rear sides of the recesses by a moving die of a receiving member, a plurality of pairs of punches are moved towards each other, to thereby press flat press portions of the punches against the support, thus drawing the support locally into the recesses of the cylinder without forming projections in an inner surface of the cylinder.
A bracket mounting structure for mounting a bracket on a tube, said tube having a recess formed in an outer circumferential surface thereof, wherein said bracket is securely joined to the tube by fitting the bracket around the tube and deforming the bracket locally into the recess without causing any substantial deformation of an inner circumferential surface of the tube.
A bracket mounting method comprising the steps of:
