Apparatus module

An apparatus module, comprising:

• a support disposed in an in-roof space between a roof panel and an interior member in a vehicle to be fixed to the roof panel;
• and
• an apparatus fixed to the support and having a casing, wherein
• the support is provided with a heat receiver comprising metal, wherein the heat receiver contacts the apparatus to receive heat from the apparatus and a heat radiator radiating heat received by the heat receiver, and wherein the heat radiator comprises metal,
• the heat receiver and the heat radiator are provided in positions away from each other in a surface of the support,
• wherein the heat receiver is provided to an upper surface of the support, and the heat radiator is provided to the upper surface, a side surface, or a lower surface of the support,
• heat is transferred from the heat receiver to the heat radiator via a heat transfer path connecting the heat receiver and the heat radiator in the support,
• the heat transfer path includes a path passing from a vertically-upper side to a lower side from the heat receiver toward the heat radiator,
• wherein an upper surface of the casing of the apparatus is opposed to the roof panel and heat is transferred from the vertically-upper side to the lower side in at least a part of the heat transfer path, and
• wherein the vertically-upper side is closer to the roof panel than the lower side is to the roof panel.
