PROBLEM TO BE SOLVED: To provide a rotary injection device capable of being easily assembled with simple components.SOLUTION: A rotary injection device includes an injection sleeve 2 and a rotary scattering tube 3. The injection sleeve 2 is a hollow tube body having side sections fixed to an injection device body 1. The rotary scattering tube 3 includes a transport tube body 31 and a bent tube body 32 connected to each other. The transport tube body 31 is passed through the injection sleeve 2. In the transport tube body 31, a front bearing 41 is externally fitted to one side section to be a side close to the bent tube body 32 while a rear bearing 42 is externally fitted to the other side section. The rotary scattering tube 3 includes a front position regulation section 33 and a rear position regulation section 34. In the front position regulation section 33, the rotary scattering tube 3 is projected on the radial direction side and is locked on a front side of the front bearing 41. In the rear position regulation section 34, the rotary scattering tube 3 is projected on the radial direction side and is locked on a rear side of the rear bearing 42. |
