A frame structure of a loom includes a frame formed by connecting a pair of side frames, to each of which a beam support for supporting a warp beam is fixed, by a plurality of beam materials, and one or more pair of height position setting members arranged between a loom installation surface and each of the side frames. Each of the height position setting members is fixed to the installation surface and the corresponding side frame. The pair of height position setting members are provided as a support structure configured such that a fixed position with respect to the corresponding side frame on at least one of a let-off side and a take-up side is an inner surface or an outer surface of the side frame.

A loom includes a pair of support shafts each provided to each of a pair of side frames and configured to rock, a rocking shaft connected to both the support shafts and bridged between the support shafts, a bearing structure comprising a bearing configured to rotatably support the rocking shaft, and a support body having an attaching surface, which is a surface to which the bearing structure is attached, and provided to extend in a weaving width direction. The support body has a position adjusting surface parallel to the attaching surface on at least one of both ends in a length direction.

An intermediate receiving mechanism includes a base member capable of supporting both shaft end portions, a lever member for clamping both shaft end portions, and two beam support sets arranged side by side, corresponding to respective warp beams. Each beam support sets is constituted by two or more supporting rollers on the base member side and a contact part including one or more contact rollers on the lever member side. The lever member includes a swing member swings about a swing shaft and supports both the contact parts. Support positions on the swing member for both the contact parts are positions where a line segment connecting the support position for one contact part and a shaft center of the swing shaft forms an angle with respect to a line segment connecting the support position for the other contact part and the shaft center.
