  We present a search for new heavy particles, $X$, which decay via $X
rightarrow WZ \to e\nu +jj$ in $p{\bar p}$ collisions at $\sqrt{s} = 1.8$ TeV.
No evidence is found for production of $X$ in 110 pb$^{-1}$ of data collected
by the Collider Detector at Fermilab. Limits are set at the 95% C.L. on the
mass and the production of new heavy charged vector bosons which decay via
$W'\to WZ$ in extended gauge models as a function of the width, $Gamma (W')$,
and mixing factor between the $W'$ and the Standard Model $W$ bosons.
