Abstract
A sliding bearing is made of a resin and includes a tubular portion that includes an outer peripheral surface including a D-cut surface. A flange portion, which protrudes from the D-cut surface, is formed at one end portion of the tubular portion. An engagement portion is formed at the other end portion of the tubular portion. A protruding portion is formed on the outer peripheral surface of the tubular portion at a circumferential position that is outside a region in which the D-cut surface is formed and that is outside a region in which the engagement portion is formed.
Claims15
A sliding bearing inserted in a through-hole and made of a resin, the through-hole formed in a support plate, the sliding bearing comprising:
- a tubular portion including an outer peripheral surface, the outer peripheral surface including a D-cut surface;
- a flange portion formed at one end portion of the tubular portion and protrudes from the D-cut surface;
- an engagement portion protruding from a part of the outer peripheral surface of the tubular portion at another end portion of the tubular portion;
- and
- a protruding portion formed on the outer peripheral surface of the tubular portion at a circumferential position, the circumferential position being outside a region in which the D-cut surface is formed and being outside a region in which the engagement portion is formed.
A sliding bearing inserted in a through-hole made of a resin, the through-hole formed in a support plate, the sliding bearing comprising:
- a tubular portion including an outer peripheral surface, the outer peripheral surface including a D-cut surface;
- a flange portion formed at one end portion of the tubular portion and protruding from the D-cut surface;
- and
- a protruding portion formed on an end portion of the D-cut surface in a direction perpendicular to an axial direction of the tubular portion.
