PURPOSE:To facilitate judgement of residual amt. of a viscous material by enabling indication of moved distance of a pressing bar which extrudes the viscous material. CONSTITUTION:An indicating section comprises an indication window 4 formed on the upper side surface of a main body 1 and an indicating plate 5 located in the interior of the window 4. The indicating plate 5 is supported freely rotatably by a pin fixed to a bearing plate 57 provided to a gear box 9; teeth are formed on its external peripheral surface, which mesh with a gear 56 rotating integrally with a pinion 8 which meshes with the rack of a pressing bar 3. Accordingly, in accordance with the advance of the pressing bar 3 by the rotation of the pinion 8, the indicating plate 5 is also rotated. In this case, the reduction ratio of the indicating plate 5 to the gear 56 should be controlled so as to determine the rotation of the indicating plate 5 to be <=1 rotation for the full stroke of the pressing bar 3. |
