1. A hinge device comprising:
a first hinge body (10) having a pair of side walls (11),
a second hinge body (20) provided on a front side of the first hinge body (10) and
a link mechanism (30) interposed between the first hinge body (10) and the second hinge body (20),
the link mechanism (30) comprising:
a moving link (30) supported by the first hinge body (10) so as to be movable in a front-rear direction, the moving link (30) having a pair of side walls (31) and a front end portion rotatably connected to the second hinge body (20),
a front connecting link (50) having a proximal end portion rotatably connected to a front end portion of the first hinge body (10) and an intermediate portion rotatably connected to an intermediate portion of the moving link (30), and
a supporting link (60) having one end rotatably connected to a distal end of the front connecting link (50) and the other end rotatably connected to the second hinge body (20);
wherein the hinge device is configured such that the pair of side walls (31) of the moving link (30) overlap an outside of the pair of side walls (11) of the first hinge body (10);
wherein the front connecting link (50) has a main part (50x) connected to the first hinge body (10), the moving link (30) and the supporting link (60) and a pair of spacers (57) made of resin interposed between the pair of side walls (11) of the first hinge body (10) and the pair of side walls (31) of the moving link (30);
wherein the main part (50x) of the front connecting link (50) has a proximal end side connecting portion (51) that enters between the pair of side walls (11) of the first hinge body (10) and is rotatably connected to the front end portion of the first hinge body and an intermediate connecting portion (52) that enters between the pair of side walls (31) of the moving link (30) and is rotatably connected to the intermediate portion of the moving link (30), and at least both sides of the proximal end side connecting portion (51) and the intermediate connecting portion (52) are made of resin, and
wherein the pair of spacers (57) extends between the intermediate connecting portion (52) of the main part (50x) and the proximal end side connecting portion (51), a pair of slits (58) are formed between both side surfaces of the main part and an inner surface of the pair of spacers, and the pair of side walls (11) of the first hinge body (10) enters the pair of slits.
