Abstract

PURPOSE: To enable the fitting inclination of a diffuser vane to be changed with a simplified construction and a high accuracy by using an arm fixed on the support shaft of said diffuser vane, a guide ring provided with a guide groove, and a Sam mechanism.
CONSTITUTION: An arm 5 is fixed on the support shaft 3 of a diffuser vane 1, and a globular guide device 6 is formed on the tip thereof to engage a guide groove 17a. When a driving shaft 15 is rotated by a driving machine or a lever 14, therefore, a plate cam 13 rotates to transfer a rod 10 axially. Said guide groove 17a is provided on a circular guide ring 17 concentric with a rotary shaft 18 and inclined with respect to circumferential direction. Therefore, said guide device 6 is moved circumferentially (orthogonally with paper surface) to rotate said support shaft 3 and said diffuser vane fixed thereon. Thereby, the fine change of the fittig inclination thereof can be performed with a high accuracy.
