Coupling mechanism, coupling mechanism group, and antenna device

A coupling mechanism comprising:

• a plate-like member group including (i) a first plate-like member which is joined to a heat generating element and (ii) a second plate-like member which is joined to a radiator;
• and
• a shaft member configured to hold the first plate-like member and the second plate-like member so as to allow the first plate-like member and the second plate-like member to rotate on a shared axis which is orthogonal to main surfaces of the respective first and second plate-like members, while causing a partial region of the main surface of the first plate-like member to be in plane contact with a partial region of the main surface of the second plate-like member,
• wherein:
• the first plate-like member includes two or more first plate-like members and the second plate-like member includes two or more second plate-like members;
• and
• the first plate-like member and the second plate-like member are alternately provided.

An antenna device comprising:

• a coupling mechanism, the coupling mechanism comprising:
• a plate-like member group including (i) a first plate-like member which is joined to a heat generating element and (ii) a second plate-like member which is joined to a radiator, and
• a shaft member configured to hold the first plate-like member and the second plate-like member so as to allow the first plate-like member and the second plate-like member to rotate on a shared axis which is orthogonal to main surfaces of the respective first and second plate-like members, while causing a partial region of the main surface of the first plate-like member to be in plane contact with a partial region of the main surface of the second plate-like member;
• the heat generating element;
• and
• the radiator,
• the heat generating element being an antenna substrate including an integrated circuit and an antenna.
