Bushing for claw machine crane

A bushing for a claw machine crane, comprising:

• an inner sleeve made of plastic and defining an axis, said inner sleeve including a sleeve tube portion defining a through hole extending therethrough in an axial direction of the axis, and a plurality of equiangularly spaced-apart insertion ribs projecting radially outward from an outer peripheral surface of said sleeve tube portion, said sleeve tube portion having an outer diameter that increases from a first end to a second end of said sleeve tube portion that is opposite to said first end in the axial direction, and an inner diameter that is constant along a length of said sleeve tube portion, each of said insertion ribs having a thickness in a radial direction that decreases from said first end to said second end of said sleeve tube portion, a sum of a thickness of said sleeve tube portion in the radial direction and the thickness of a corresponding one of said insertion ribs being constant in the axial direction;
• and
• a bushing body including a bushing body tube portion extending in the axial direction and defining an insertion hole extending therethrough in the axial direction for insertion of said inner sleeve thereinto, and an annular flange projecting radially outward from an outer peripheral surface of said bushing body tube portion in proximity to one end of said bushing body tube portion.
