Document Type and Number:
Japanese Patent JP2022155653
Kind Code:
A
Abstract:
To automate the opening and closing movements of swing doors, while suppressing, even upon the automation, the vertical vibration that is caused at a rotating part in which a tip part of a transmission member and a tip part of a rotation member are rotatable.SOLUTION: A swing door mechanism transmits the rotation created with a motor to a follower pulley 54 arranged on the revolving shaft of an electromagnetic brake 52 via a main pulley and a timing belt 35, and comprises a transmission member 60 of which a tip part 60a is connected to the revolving shaft of the electromagnetic brake 52, and a rotation member 62 that is rotatably connected to the other tip 60c of the transmission member 60 via a first rotation part 70. The first rotation part 70 comprises a bolt 72 that comprises a shank part 72d that is movably inserted through the first and second holes.
