Abstract: Provided is a sliding door device which can move a support shaft attached to a sliding door along an inclined portion of a rail by using a pull-in device. The rail (6a) is provided with the straight portion (11) for linearly guiding the support shaft attached to the sliding door (2) and the inclined portion (12) which is inclined with respect to the straight portion (11) and obliquely guides the support shaft. The straight portion (11) of the rail (6a) is provided with the pull-in device (15) which can capture a trigger (18) provided on the straight portion (11) of the rail (6a) and linearly move along the straight portion (11) of the rail (6a) when the sliding door (2) is closed. A pull-in force transmission part (20) for moving the support shaft along the inclined portion (12) of the rail (6a) is coupled to the pull-in device (15).

Abstract: A hinge device 1 comprises a dumper hinge 2 and a gravity hinge 3. The gravity hinge 3 comprises a rotational force imparting mechanism 70 for converting gravity of the door 6 to rotational force to a closing direction when the door 6 rotates to the closing direction. The dumper hinge 2 comprises a dumper mechanism 30 for reducing the rotational force to the closing direction of the door 6. The dumper mechanism 30 includes a linear dumper 31 disposed to the first hinge member 10 and a first cam member 32 and includes a second cam member 35 disposed to the second hinge member 20. The linear dumper 31 is positioned far from the shaft member 40 in an orthogonal direction to a shaft line of the shaft member 40 and is positioned along the shaft member 40. When the door 6 rotates, the linear dumper 31 is shortened.
