To provide a technique which can shorten the maintenance time for a liquid feeding apparatus for feeding a liquid having viscosity such as a primer liquid and increase the operable time.
In a primer liquid feeding apparatus 32 which feeds the primer liquid having viscosity, the primer liquid feeding apparatus 32 consists of a primer liquid container 36 storing the primer liquid, an elastically deformable tube 33, a primer liquid gun 13, and a tube pumping mechanism 39. In this case, the proximal section 37 of the elastically deformable tube 33 is inserted in the primer liquid container 36, and the distal end 38 of the elastically deformable tube 33 is extended to an application place. The primer liquid gun 13 is detachably fitted on the distal end 38 of the tube 33. The tube pumping mechanism 39 is installed halfway in the tube 33, and continuously draws the tube 33 from the proximal part 37 to the distal part 38.
