PROBLEM TO BE SOLVED: To provide a stationary agitator for a curable mixture product, which has a prolonged service life. SOLUTION: This agitator includes one stationary member 1 and one tube surrounding the stationary member. The stationary member has a chamber structure comprising a plurality of mixture chambers 2. The mixture chambers are arranged in a back-and-forth relationship along a tube axial line 10. These mixture chambers 2 are mutually comparted by radial longitudinal walls 3a, 3b, 3c, 3d oriented in the tube axial line direction and cross walls 4a, 4b oriented across the tube axial line. Openings 5a, 5b, 5c, 5d of the radial longitudinal walls between the adjacent mixture chambers 2 serve as an inlet and an outlet for the mixture product. The two parallel outer side longitudinal walls constitute the outer face of the mixture chamber. Regarding at least several mixture chambers, each of one cross wall 4b and one first outer face 6a constitutes a corner, and a wall material is partially provided on the corner. This fillet, that is, a first corner fillet 7 forms a concave face 7a relative to the internal space of the mixture chamber. COPYRIGHT: (C)2006,JPO&NCIPI
