Isolated turbulent bands observed in transitional channel flows havedownstream heads and inclined bulks at a characteristic angle. In thelarge-scale mean flow, a $\nu$-shape vortex found at the head elongates intothe bulk part, forming a pair of counter-rotating vortex tube structures. It isrevealed numerically and theoretically that the head and the bulk convectionvelocities reflect the obliquely forward and the backward self-inducedvelocities of the $\nu$-shape vortex and the vortex tube pair, respectively,and the difference between these convection velocities provides a restoringangular momentum to retain the characteristic inclination angle through aself-adjustment process.
