PURPOSE: To ensure unchanging of a position relation between a component and a carrier through suppression of the mechanical stress of a mounting part by a method wherein a curved support beam has an outside mounting protrusion piece fixed in a spaced-away mounting spot at a component, and a protrusion piece extending laterally externally of the support beam is fixed in a central position between outside protrusion pieces and in an intermediate mounting spot with a carrier. CONSTITUTION: During operation of a transmission device, with the progress of heating of parts and a case, a support beam 26 is expanded in a further speedy ratio than that of a transmission device part. As a result, the part 10 applies a compression load on the support beam, which is bent in an external direction. This operation externally moves the mounting spot of a protrusion piece 38. With the progress of thermal expansion of the case, the mounting spot 22 of the rib 16 of the case is also externally moved. A mount 24 is brought into a proper size shape and by forming the mount of a material having a correct expansion factor relation, the mounting spots of the protrusion piece 38 and the rib 16 are moved in the same ratio during a heat cycle. As a result, a lateral stress having shearing operation in a common mounting spot 22 is rendered ineffective. |
