The invention claimed is: 1. A variable nozzle device comprising a wall member (10), a unison ring (12), and a plurality of vanes (1), wherein each vane (1) has a vane body (2) and a tab member (9) that slidingly engages the unison ring (12), the tab member (9) comprising a tab portion (5) and a shaft portion (6), said shaft portion (6) passing through a slot (11) of the wall member (10), and said tab portion (5) overlapping the slot (11) to hold the vane (1), characterized in that the vane body (2) and the tab member (9) are provided as separate parts and are fixable to each other wherein the tab portion (5) and the vane body (2) slidingly grip the wall member (10) there between. 2. The variable nozzle device according to claim 1, wherein a mounting hole (7) is provided in the vane body (2) at a side of the vane body (2) which faces the wall member (10), and a tip section (3) of the shaft portion (6) is insertable into the mounting hole (7) of the vane body (2). 3. The variable nozzle device according to claim 2, wherein the tab member (9) is fixable to the vane body (2) by press-fitting the tip section (3) of the shaft portion (6) into the mounting hole (7). 4. The variable nozzle device according to claim 2 or 3, wherein the tip section (3) and the mounting hole (7) have corresponding cross-sectional shapes which fit to each other and which provide a relative rotation preventing means for preventing a rotation of the tab member (9) relative to the vane body (2). 5. The variable nozzle device according to claim 2, wherein the shaft portion (6) comprises a spacing section (4) disposed between the tip section (3) and the tab portion (5), said spacing section (4) defining a predetermined distance between the tip section (3) and the tab portion (5). 6. The variable nozzle device according to claim 5, wherein the cross-sectional area of the spacing section (4) is larger than the cross-sectional area of the tip section (3) to form a stop face (14) which restricts the insertion depth of the tab member (9). 7. The variable nozzle device according to claim 5, wherein the wall member (10) comprises a slotted portion (15) having the slot (11) through which the shaft portion (6) of the tab member (9) is passed, and wherein the length of the spacing section (4) is set based on a thickness of the slotted portion (15) such that the tab portion (5) and the vane body (2) slidingly grip the wall member (10) there between. 8. The variable nozzle device according to claim 1, wherein wherein the slot (11) is shaped in such a manner that the vane (1) is held by the tab portion (5) disregarding the position of the vane (1) with respect to the wall member (10). 9. The variable nozzle device according to claim 1, wherein the slot (11) is curvilinear. 10. A method of assembling a variable nozzle device comprising a wall member (10), a unison ring (12), and a plurality of vanes (1), wherein each vane (1) has a vane body (2) and a tab member (9) that slidingly engages the unison ring (12), the tab member (9) comprising a tab portion (5) and a shaft portion (6), the method comprising the steps of arranging the vane body (2) on one side of the wall member (10), passing the shaft portion (6) of the tab member (9) through the slot (11) from another side of the wall member (10), and fixing the shaft portion (6) to the vane body (2) wherein the tab portion (5) of the tab member (9) and the vane body (2) slidingly grip the wall member (10) there between. 11. The method according to claim 10, wherein the shaft portion (6) is fixed to the vane body (2) by inserting a tip section (3) of the shaft portion (6) into a mounting hole (7) of the vane body (2). 12. The method according to claim 10, wherein, before passing the shaft portion (6) of the tab member (9) through the slot (11), a mounting hole (7) of the vane body (2) is aligned with the slot (11) of the wall member (10); and fixing of the shaft portion (6) to the vane body (2) is made by press-fitting a tip section (3) into the mounting hole (7). 13. The method according to claim 10, wherein before performing the step of inserting the shaft portion (6) of the tab member (9) through the slot (11) of the wall member (10) into a mounting hole (7), performing the steps of arranging the unison ring (12) having an actuating slot (13) on said second side of the wall member (10), aligning the actuating slot (13) with the slot (11) of the wall member (10), and then inserting the shaft portion (6) through said actuating slot (13) of the unison ring (12) to place the tab portion (5) in said actuating slot (13). 14. The method according to claim 10, further comprising the step of pressing a tip portion (3) of the tab member (9) into a mounting hole (7) of the vane body (2) until the stop face (14) of the tab member (9) abuts against the vane body (2). 15. A variable nozzle device comprising a wall member (10), a unison ring (12), and a plurality of vanes (1), wherein each vane (1) has a vane body (2) and a tab member (9) comprising a tab portion (5) and a shaft portion (6), said shaft portion (6) passing through a slot (11) of the wall member (10), and said tab portion (5) overlapping the slot (11) to hold the vane (1), characterized in that the vane body (2) and the tab member (9) are provided as separate parts and are fixable to each other wherein the tab portion (5) and the vane body (2) slidingly grip the wall member (10) there between; wherein a mounting hole (7) is provided in the vane body (2) at a side of the vane body (2) which faces the wall member (10), and a tip section (3) of the shaft portion (6) is insertable into the mounting hole (7) of the vane body (2). 16. A method of assembling a variable nozzle device comprising a wall member (10), a unison ring (12), and a plurality of vanes (1), wherein each vane (1) has a vane body (2) and a tab member (9) comprising a tab portion (5) and a shaft portion (6), the method comprising the steps of arranging the vane body (2) on one side of the wall member (10), passing the shaft portion (6) of the tab member (9) through the slot (11) from another side of the wall member (10), and fixing the shaft portion (6) to the vane body (2) wherein the tab portion (5) of the tab member (9) and the vane body (2) slidingly grip the wall member (10) there between; wherein the shaft portion (6) is fixed to the vane body (2) by inserting a tip section (3) of the shaft portion (6) into a mounting hole (7) of the vane body (2).
