Abstract
To eliminate pins for specifying a vertical position of a metal fixture from a dust cover forming mold to suppress variation in product shape caused by wear of the pins, the ring-shaped metal fixture is embedded in the dust cover to fix the dust cover at an installation position, inner diameter teeth are formed integrally at one end in the axial direction of an outer diameter tube section via a bend, the metal fixture is embedded in the dust cover so that one end in the axial direction of the bend is set at axially the same position as one end face in the axial direction of the dust cover, and groove communication sections radially penetrating the bent section are formed in a radial shape at the one end.
Claims1
A metal fixture embedded in a dust cover for fixing the dust cover at an installation position, the metal fixture comprising:
- an outer diameter tube section;
- and
- an inner diameter teeth section formed integrally with the outer diameter tube section at one end in an axial direction via a bend therebetween, the inner diameter teeth section having a conical surface shape as a whole,
- wherein the metal fixture is ring-shaped and embedded in the dust cover so that the one end in an axial direction of the bend is set at axially the same position as one end face in the axial direction of the dust cover,
- wherein the bend includes through-holes in the form of a plurality of spaced apart discrete grooved-shaped communication sections radially penetrating the bend in a radial shape at the one end in the axial direction of the bend and also penetrating the bend in a thickness direction so that each communication section opens at an inner end face of the bend, and
- wherein the inner diameter teeth section has a continuous ring shape as a whole adjacent the bend.
