Applying squashing transformation to the Kerr-Godel black hole solution, we present a new type of a rotating Kaluza-Klein black hole solution in the five-dimensional minimal supergravity. The new solution generated by the squashing transformation has no closed timelike curve outside the black hole horizons. The spacetime is asymptotically locally flat. One of the remarkable features is that the solution has two independent rotation parameters along an extra dimension associated with the black hole's rotation and Godel's rotation. The spacetime also admits the existence of two disconnected ergoregions, an inner ergoregion and an outer ergoregion. These two ergoregions can rotate in opposite directions as well as in the same direction.
