An exhaust pipe supporting device includes a generally elliptical body portion integrally formed of an elastic material, such as rubber. The body portion includes a first holder portion having a through-hole to receive a support member associated with a car body, a second holder portion having another through-hole to receive a support member associated with the exhaust pipe. A pair of lateral walls connect the first and second holder portions by attachment at opposite ends to opposed sides of the first and second holding portions. The first and second holding are held in this manner in spaced apart relation to each other, and a central connector is disposed intermediate between the first and second holder portions and connected at opposite sides thereof to the lateral walls. The central connector portion includes a central portion formed as a mass section, which optionally includes a metal mass portion, and opposite lateral portions which extend from the mass section to the opposite sides. The mass section is heavier than the opposite portions, the latter which are bifurcated to provide branch portions advantageously diverging at a branch angle in a range between 30 and 60 degrees.
