Abstract
A shock absorber includes a shock absorber body having a cylinder outer shell and a piston rod capable of going in/out of the outer shell and generating 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 allowing entry of the outer shell into an inside, and a cylindrical collar attached to the outer shell and arranged on an outer periphery of the piston rod.
Claims9
A shock absorber comprising:
- 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, and
- a 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.
