  • Patent number: 9919593
    Abstract: A mount device includes an inner rod, a damper made of an elastic material to be mounted to the inner rod, and an outer cover to be mounted to the damper. The damper includes a plurality of projecting portions projecting radially outward from the inner rod and small-thickness portions thinner than the plurality of projecting portions in a radial direction. Spaces are formed radially outward of the small-thickness portions. The outer cover includes a plurality of contact surfaces to respectively come into contact with the plurality of projecting portions. The contact surfaces have a larger curvature than that of a circumscribed circle of the damper.
