First Claim
1. A conveying roller being adapted to be mounted to a vertical wall (1) having a threaded hole (29), a supporting hole (28) and a peripheral wall portion all arranged in series in a substantially horizontal direction, the supporting hole (28) having a bottom wall (28a), said conveying roller comprising;
- a support cylinder (12) having a bore (15) and provided with a supporting portion (22) extending into the supporting hole (28) and a bearing portion (23) supporting a roller member (14);
a clearance (C) provided between the bottom wall (28a) of the supporting hole (28) and the supporting portion (22);
an annular flange portion (25) provided about a predetermined section of the supporting portion (22), between the bearing portion (23) and the peripheral wall portion; and
a bolt (16) adapted to be inserted into the bore (15) and to be screwed into the threaded hole (29) so that the flange portion (25) is pressed against the peripheral wall portion through the support cylinder (12) by a tightening force of the bolt (16).

Abstract
In a movable plate (1) of an injection moulding machine, there are arranged a threaded hole (29) and a supporting hole (28) in series in the substantially horizontal direction. A supporting portion (22) of a support cylinder (12) is fitted into the supporting hole (28), and a roller member (14) is externally rotatably fitted to a bearing portion (23) of the support cylinder (12). An annular flange portion (25) is provided between the supporting portion (22) and the bearing portion (23). An outer diameter (D) of the flange portion (25) is so set as to be larger than an inner diameter (A) of the supporting hole (28) and to be smaller than an outer diameter (B) of the roller member (14). The bolt (16) is screwed into the threaded hole (29) so as to press the flange portion (25) onto the movable wall (1) through the support cylinder (12).
