Door module and door module fixture

1. A door module fixture used for fixing the door module to the door inner panel in which a door harness is routed in advance on a closing plate made of resin for closing a service hole provided in a door inner panel of an automobile, comprising:

an elastic fitting portion protruding to an outer side of an inner circumferential edge of the service hole from an outer circumferential edge of the closing plate,

wherein the elastic fitting portion is provided with a first recessed groove that opens in the center of a protruding end surface of the elastic fitting portion and extends in the circumferential direction to accommodate the inner circumferential edge of the service hole, and the inner circumferential edge of the service hole is clamped between a pair of elastic clamping pieces that face each other with the first recessed groove interposed between the pair of elastic clamping pieces, and

the elastic fitting portion is provided with a second recessed groove that opens in the center of a base end surface of the elastic fitting portion and extends in the circumferential direction to accommodate the outer circumferential edge of the closing plate, and the outer circumferential edge of the closing plate is held between a pair of holding pieces that face each other with the second recessed groove interposed between the pair of holding pieces.

2. The door module fixture according to claim 1 , wherein

on the outer circumferential edge of the closing plate, the elastic fitting portion projects with a thickness larger than the plate thickness of the closing plate and extends in the circumferential direction of the outer circumferential edge, while the outer circumferential edge of the closing plate is held by the second recessed groove.

3. The door module fixture according to claim 1 , wherein

a protruding dimension of the elastic fitting portion from the outer circumferential edge of the closing plate is set according to the difference in a facing gap size between the outer circumferential edge of the closing plate and the inner circumferential edge of the service hole so as to clamp the inner circumferential edge of the service hole between the pair of elastic clamping pieces and hold the outer circumferential edge of the closing plate between the pair of holding pieces.

4. The door module fixture according to claim 1 , wherein

the elastic fitting portion is formed of a rubber elastic body.

5. A set of the door module fixture, comprising:

a plurality of types of the door module fixture according to claim 1 ,

wherein the elastic fitting portion of each of the plurality of types of the door module fixture has a different protruding dimension from the outer circumferential edge of the closing plate according to the difference in a facing gap size between the outer circumferential edge of the closing plate and the inner circumferential edge of the service hole.

6. A method of manufacturing a door part by using the door module fixture according to claim 1 , using the closing plate for a plurality of vehicle types, wherein

a plurality of types of the door module fixture are prepared, the elastic fitting portion of each of the plurality of types of the door module fixture has a different protruding dimension from the outer circumferential edge of the closing plate according to the difference in a facing gap size between the outer circumferential edge of the closing plate and the inner circumferential edge of the service hole,

the door module fixture corresponding to the vehicle type to be manufactured is selected from the plurality of types of the door module fixture, and attached to the closing plate, and

the closing plate is fixed to the door inner panel by the door module fixture so as to close the service hole by the closing plate.
