To provide a dispenser for a dental viscous material where the viscous material is not discharged from the inside of a cartridge against will. The dispenser for the dental viscous material comprises a guide shaft 1, a slide block 2, a housing 3, and a lever main body 4. The guide shaft 1 has a cylindrical part 1ba at a front end thereof, a guide member 1b having a large diameter part 1bba and a small diameter part 1bbb on the rear side of the cylindrical part 1ba, and a knob for rotating the guide shaft 1h at a rear end thereof. The slide block 2 has a release plate 2c inserted with the guide shaft 1 and piston shafts 2b on the both side. The housing 3 has pressing springs 3ea, which support the guide shaft 1 rotatably and slidably and press each piston shaft 2b. The lever main body 4 has a lever part 4a and a pressing piece 4b. The lever part 4a is rotated by a predetermined angle from an initial position being in approximately parallel to the upper face of the housing 3, and the pressing piece 4b is projected at a lower part on the front end side of the lever part 4a. The pressing piece 4b is inserted into the small diameter part 1bbb at the initial position and rotated when the guide shaft 1 is rotated. Then, the pressing piece 4b is moved in the rear direction to thereby upwardly rotate the lever part 4a by the predetermined angle, and is contacted with a rear face of the large diameter part 1bba. Further, when the lever part 4a is pressed, the pressing piece 4b moves the large diameter part 1bba in the front direction. |
