a shock absorber body having a cylindrical outer shell, and a piston rod capable of going in/out of the outer shell and adapted to generate a damping force suppressing relative movement of the piston rod in an axial direction with respect to the outer shell; a cylindrical dust cover connected to the piston rod and adapted to allow entry of the outer shell to an inside; a cylindrical collar attached to the outer shell and arranged on an outer periphery of the piston rod; a seal member; and a cylindrical seal case provided on a piston rod side end of the outer shell, the seal case having
a cylindrical large-diameter portion attached to an inner periphery of the piston rod side end of the outer shell,an annular flange portion extended from a piston rod side end of the large-diameter portion to an inner periphery side, anda cylindrical small-diameter portion having a portion extended from the inner periphery of the flange portion to a piston rod side end of the small-diameter portion, wherein the collar is mounted to the flange portion, the small-diameter portion accommodates the seal member, and the collar is welded to the flange portion so as to be fitted to the outer shell through the seal case and surround the small-diameter portion. |
