A mounting structure for mounting a cockpit module onto a vehicle body on a side facing a vehicle compartment is provided with a mount member mounting a cockpit module onto a vehicle body, a resilient member disposed between the vehicle body and the cockpit module, and a guide mechanism guiding the cockpit module along a given transfer path when the cockpit module is transferred to a mount position of the vehicle body. The guide mechanism guides the cockpit module in a way to allow the cockpit module to move downward of the vehicle body in an oblique direction through at least a partial segment of the given transfer path such that an own weight of the cockpit module is allowed to apply on the resilient member to press the resilient member between the vehicle body and the cockpit module.
