A coupling mechanism (1) includes: a plate-like member group (11) including (i) a first plate-like member (11_2) which is joined to a heat generating element (92) and (ii) a second plate-like member (11_1) which is joined to a radiator (91); and a shaft member (12) configured to hold the first plate-like member and the second plate-like member (11_1, 11_2) so as to allow the first plate-like member and the second plate-like member (11_1, 11_2) to rotate on a shared axis which is orthogonal to main surfaces of the respective first and second plate-like members (11_1, 11_2). The main surface of the first plate-like member (11_2) is in plane contact with the main surface of the second plate-like member (11_1). ## Claims ### Claim 1 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: (i) the first plate-like member is a single plate-like member, the second plate-like member includes two plate-like members, and the single plate-like member is provided between the two plate-like members so as to be opposite to the two plate-like members;

and an elastically contracted elastic member is sandwiched (i) between the head part of the bolt and the one of the two plate-like members and/or (ii) between the nut and the other one of the two plate-like members. ### Claim 6 (depends on 1) The coupling mechanism as set forth in claim 1, wherein irregularities, having ridges which radially extend from the shared axis, are provided in a partial region of main surfaces of the plate-like members that are in plane contact with each other. ### Claim 7 (depends on 1) The coupling mechanism as set forth in claim 1, wherein irregularities, having ridges which are concentrically provided around the shared axis, are provided in a partial region of main surfaces of the plate-like members that are in plane contact with each other. ### Claim 8 (depends on 1) A coupling mechanism group comprising: a plurality of coupling mechanisms, each of the plurality of coupling mechanisms being a coupling mechanism recited in claim 1, in said each of the plurality of coupling mechanisms, each first plate-like member being joined to a corresponding heat generating element via a shared support, in said each of the plurality of coupling mechanisms, each second plate-like member being joined to a corresponding radiator via a shared support. ### Claim 9 (depends on 1) An antenna device comprising: a coupling mechanism recited in claim 1;
