Abstract: We prove the existence of solutions of a differential inclusion $u'\in F(t,u)$ in a separable Banach space $X$ with constraint $u(t)\in D(t)$. $F$ is globally measurable, weakly upper semicontinuous with respect to $u$ and takes convex, weakly compact values. $D$ is upper semicontinuous from the left, and, for every $r>0$, the sets $D(t)\cap rB$ are compact. $F$ and $D$ fulfil a well-known tangential condition, which is expressed by means of the Bouligand cone.
