PROBLEM TO BE SOLVED: To provide an applicator for high viscous material especially in which outflow of additive material can be securely prevented. SOLUTION: In an applicator for high viscous material especially comprising a case member 12 and a piston rod 16 supported inside it, this piston rod 16 is movable forward through two jamming elements 28, 30 which are disposed forward and back by move of an actuation element 14 from a static position to an actuation position. In actuation of the actuation element 14, the actuation jamming element 30 jams to be movable forward with the piston rod 16. The lock jamming element 28 is jammed backward by spring load to be supported on the case member 12. The actuation element 14 actuates on a connection rod 42 in moving in an inverse direction to an actuation direction, so it releases the lock jamming element 28. |
