Claim 0:
1. A wheel comprising:
a spoke formed with a mounting hole that extends in a radial direction of said wheel, and blind hole that extends in an axial direction perpendicular to the radial direction and that is in spatial communication with said mounting hole;
a rim connected to said spoke and formed with a through hole that extends in the radial direction and that is aligned with said mounting hole; and
a connecting unit connecting said spoke with said rim and including
a rod extending through said through hole into said mounting hole, and being formed with an engaging hole that extends in the axial direction and that is aligned with said blind hole, and
a fastener extending through said blind hole into said engaging hole and engaging with said engaging hole;

wherein said rod includes a rod body that is formed with said engaging hole, and a head portion that is connected to said rod body at a position opposite to said engaging hole and that engages with a portion of said through hole;
wherein viewing in the radial direction, said head portion has a contour that has a shape substantially of a major segment of a circle, and said through hole has an opening matching with said head portion;
wherein said rim has an internal surface that defines said opening of said through hole;
wherein said head portion has
a curved surface corresponding to an arc of the major segment and having two opposite ends, and
a planar surface corresponding to a chord of the circle that cooperates with the arc to define the major segment, and being connected between said two opposite ends of said curved surface; and

wherein said curved surface and said planar surface fittingly abut against said internal surface.
