Abstract: A corner bracket of a side mirror for an automobile comprises an attaching member for accessory attaching, with a nearly triangular form, having an outer size sufficient to close an angle part formed between a door belt line and a slant pillar disposed on the upper side of the door belt line, and an attaching foot member extending from the attaching member to be fixed to the door body. The attaching member comprises an insert of U-like cross-section coated with high molecular weight elastic material, a glass-enclosing groove, and an attaching hole crossing the glass-enclosing groove. A cylindrical flash formed surrounding the attaching hole is molded having a weakened portion expected to be broken at one end and the weakened portion is cut during the mold releasing operation, whereby the removing work of the cylindrical flash becomes unnecessary after the mold releasing operation has been conducted.

Abstract: A sealing boot of elastomeric material for hermetically enclosing an annular opening between a support member and a movable member axially reciprocable on the support member, the sealing boot including a tubular bellows which is integrally formed at one end thereof with a first cylindrical sealing sleeve portion coupled over the support member and at the other end thereof with a second cylindrical sealing sleeve portion coupled within the movable member, the sealing boot being characterized in that the first cylindrical sealing sleeve portion being connected substantially at its center to the one end of the tubular bellows and being formed at its inner end shoulder with an annular thick wall tapering radially toward the inner wall surface of the tubular bellows.
