A cab mounting assembly connecting a cab and a frame is configured so that grease is supplied to contact portions to prevent wear and noise. The cab mounting assembly hinge-connects a frame of a vehicle and a cab in which an occupant sits. A collar is disposed outside a fixing bolt hinge-connecting the frame and the cab. A hinge cushion is fitted around the collar to buffer vibration transmitted to the cab. At least one surface of an internal surface of the hinge cushion and an external surface of the collar is provided with a groove through which oil supplied into the hinge cushion flows to an end portion of the hinge cushion.
