  • Patent number: 10047818
    Abstract: A damping device has a pin member inserted slidably in a cylindrical case member. The bottom of the case member has: a hole forming section in which an insertion hole is formed; and a slit for allowing the hole forming section to be expanded and deformed. The outer peripheral surface of the pin member and/or the inner peripheral surface of the hole forming section has a tapered section tilted relative to the axial direction. The movement of the pin member of being pressed into the insertion hole from the inside causes the outer peripheral surface of the pin member and the inner peripheral surface of the hole forming section to slide on each other along the tapered section, and as a result, the insertion hole is expanded.

  • Publication number: 20170370140
    Abstract: A stopper device includes: a stopper that has an abutting part located at a distal end of a tubular part in the axial direction, and a through-hole penetrating through the abutting part and communicating with the inside of the tubular part; and a screw that has a flange-shaped screw head accommodated in the tubular part, and a shaft projecting toward a proximal end side of the tubular part in the axial direction. The tubular part has a first restricting part that restricts movement of the stopper toward the distal end in the axial direction by being engaged with the screw head. The position of the stopper in the axial direction is changed by inserting a tool in the tubular part through the through-hole and rotating the screw.
