The ornamental design for a spoke unit for vehiclewheel, as shown and described.
FIG. 1 is a front elevational view of a spoke unit for vehicle wheel
showing my new design; and,
FIG. 2 is a side perspective view thereof.
The broken line showing of the rim in FIG. 1 is for illustrative purposes
only and forms no part of the claimed design. The broken lines in FIGS. 1
and 2 at the inner edge of the spokes define the inner boundary of the
claimed design and form no part thereof.
