A tubular vibration-damping device for a motor mount including: an inner shaft member; an outer tube member; and a plurality of rubber legs extending between surfaces of the inner shaft member and the outer tube member facing in a radial direction and connecting them, wherein the plurality of rubber legs include four rubber legs which mutually separate wider apart in a circumferential direction as they go to a periphery in an up-down direction and a left-right direction, for the four rubber legs, a difference in cross-sectional areas each in a leg transverse cross section orthogonal to a length direction, which is a connection direction of the inner shaft member and the outer tube member, is 20% or less, and the four rubber legs have mutually different shapes and resonant states against a vibration input in the up-down direction.
