PROBLEM TO BE SOLVED: To provide an injection device which can securely and completely inject materials especially such as dental materials. SOLUTION: This injection device for a viscous material especially such as photo-setting dental material consists of an injecting part 14 and a pushing part 20. The pushing part 20 can be partly inserted into the injecting part 14 when the material is injected. The shape of the pushing part 20 can be changed, specifically elastically, according to the shape of the injecting part 14, but the shape of the rear end part of the pushing part 20 is fixed. |
