The rotation rates in the deep interior and at the surface of 22\nmain-sequence stars with masses between $1.0$ and $1.6\\,{\\rm M}_{\\odot}$ are\nconstrained by combining asteroseismological analysis with spectroscopic\nmeasurements. The asteroseismic data of each star are taken by the {\\it Kepler}\nor CoRoT space mission. It is found that the difference between the surface\nrotation rate and the average rotation rate (excluding the convective core) of\nmost of stars is small enough to suggest that an efficient process of angular\nmomentum transport operates during and/or before the main-sequence stage of\nstars. If each of the surface convective zone and the underlying radiative\nzone, for individual stars, is assumed to rotate uniformly, the difference in\nthe rotation rate between the two zones turns out to be no more than a factor\nof two in most of the stars independently of their ages.\n
