PROBLEM TO BE SOLVED: To provide a bearing device having simplified structure and arrangement of fixedly fit elastic members allowing rectilinearly or quasi-rectilinearly moving an oscillating frame swingingly suspended on a support structure. SOLUTION: This bearing device swingingly suspends on the support structure the oscillating frame of a conveying grid including two elastic members fixedly fit to fitting points of first structure members by first end parts and arranged in line within a common swinging face where second end parts are respectively connected with connecting points of a rigid connecting device connected with second structure members by a fixedly fit manner. The elastic members 12, 14 are arranged being inclined to each other within the swinging face, and connecting device 16 tiltingly connected with the second structure members 4, 20 within the swinging face via a connection member 18.
