Abstract
A vibration isolating functional member 16 is formed of an inner cylinder 1, an outer cylinder 2, and a vibration isolating rubber 3. Thereafter an end face of a flange 10 of the outer cylinder 2 is joined with a bracket side connecting surface 15 of a bracket 4 and the joint portion thereof is laser welded. In this time, the outer peripheral end face of the flange 10 as the joining portion projects toward a position apart from the vibration isolating rubber 3 such as giving no thermal influence to the vibration isolating rubber 3. This position to give no thermal influence to the rubber is determined by an experiment based on a welded material, thickness thereof, laser welding conditions (such as melting depth, output power and welding speed), surface temperature limit of the rubber and so on.
