The wheel balancer includes a plastic one-piece body for mounting on the shaft of a wheel and also having a window. A bar is carried by the body and is slidable therein to a position where the wheel is in balance, whereupon indicia on the bar, visible through the window, informs the mechanic how much weight is to be added to the wheel to place it in balance. The bar is also rotatable about its axis, in the body, so that several labels corresponding to several wheel diameters can be provided on the same bar. A detent mechanism on the body and on the bar holds the bar in a selected rotational orientation while enabling the sliding movement during balancing.
