Claims

[Scope of utility model registration request]

In a vibration isolation structure for a crankshaft bearing part in which the mutual rigidity of a plurality of crank caps is increased, a plurality of bearing parts on which a crankshaft is supported are formed together with a cylinder block, and the bearing parts are located at both ends of the crank caps in the arrangement direction. A crankshaft bearing, characterized in that a thrust bearing that receives back pressure from lubricating oil is mounted on the side opposite to the sliding surface together with a radial bearing, and the bearing portion to which the thrust bearing is mounted is connected by at least a reinforcing beam. Anti-vibration structure.
