1. A vibration-damping device comprising:
a vibration-damping device body; and
a bracket,
wherein
the vibration-damping device body includes:
a first mounting member mounted on one of a vibration-generating portion and a vibration-receiving portion via the bracket;
a second mounting member mounted on the other of the vibration-generating portion and the vibration-receiving portion; and
an elastic body connecting the first mounting member and the second mounting member,
wherein
the first mounting member is fitted into a fitting hole formed in the bracket,
a first guide portion, which has one of a projected shape and a recessed shape extending in a first axial direction along a central axis of the fitting hole, is formed on an outer circumferential surface of the first mounting member,
a second guide portion, which has the other of the projected shape and the recessed shape extending in the first axial direction, is formed on an inner circumferential surface of the fitting hole of the bracket,
the first guide portion is fitted to the second guide portion,
the first mounting member is made entirely of a synthetic resin material,
a metal fitting having first engagement surfaces is arranged on the first guide portion,
second engagement surfaces are formed in the second guide portion,
the first mounting member includes:
a flange protruding outward in a radial direction; and
the first guide portion formed on an outer circumferential surface of the flange among the outer circumferential surface of the first mounting member,
the first engagement surfaces include:
a first surface facing in a first direction of a direction along the outer circumferential surface of the first mounting member among directions perpendicular to the first axial direction; and
a second surface facing in a second direction opposite to the first direction,
the second engagement surfaces includes:
a third surface facing in the second direction; and
a fourth surface facing in the first direction, wherein
the first surface comes into contact with the third surface,
the second surface comes into contact with the fourth surface,
the elastic body is connected to an inner circumferential surface of the first mounting member, and
the metal fitting is arranged outward in the radial direction of the first mounting member.
