Description

The present invention relates to a shutter bearing that supports the longitudinal end of a winding shaft that winds up a shutter curtain.

Bearings for heavy shutters, etc. have a structure that combines a bearing plate and a mounting base for attaching the bearing plate.By making the mounting hole on the bearing plate side a vertical hole, the bearing plate can be easily attached to the mounting base fixed to the building frame. The position in the height direction is adjustable.

In the device described in Patent Document 1, a vertically extending hole and a horizontally long hole extending in the horizontal direction are provided in the frame mounting plate to which the bracket body is attached, so that the bracket body can be fixed in the vertical and horizontal directions with respect to the frame (framework mounting plate). (opening width direction) position adjustment is possible.

However, when the mounting base is fixed to the frame, the accuracy of the frame to which the mounting base is fixed, etc. In some cases, the shaft center of the drive-side bearing and the driven-side bearing may be misaligned. In such cases, conventionally, the position of the bearing in the in/out direction was adjusted by inserting a separate plate or the like.
