In case of a triangular spin tube, the two-dimensional network of the inter-tube interaction forms characteristic lattices. Among them Kagome-Triangular (KT) lattice is known to exhibit an enriched phase diagram including various types of non-trivial structures: non-coplanar cuboc structure, coplanar 120\u00b0 structure with the two-dimensional propagation vector of $${\\boldsymbol{k}}_{2\\mathrm{D}}$$<\/jats:tex-math>\n \n \n k<\/mml:mi>\n <\/mml:mrow>\n \n 2<\/mml:mn>\n D<\/mml:mi>\n <\/mml:mrow>\n <\/mml:msub>\n <\/mml:math><\/jats:alternatives><\/jats:inline-formula>\u2009=\u2009(0, 0), $$\\sqrt 3 \\times \\sqrt 3$$<\/jats:tex-math>\n \n \n 3<\/mml:mn>\n <\/mml:msqrt>\n \u00d7<\/mml:mo>\n \n 3<\/mml:mn>\n <\/mml:msqrt>\n <\/mml:mrow>\n <\/mml:math><\/jats:alternatives><\/jats:inline-formula> structure with $${\\boldsymbol{k}}_{2{\\mathrm{D}}}$$<\/jats:tex-math>\n \n \n k<\/mml:mi>\n <\/mml:mrow>\n \n 2<\/mml:mn>\n \n D<\/mml:mi>\n <\/mml:mstyle>\n <\/mml:mrow>\n <\/mml:msub>\n <\/mml:math><\/jats:alternatives><\/jats:inline-formula>\u2009=\u2009(1\/3, 1\/3), and incommensurate structure. We investigate the magnetic state in the model material CsCrF4<\/jats:sub> by using neutron diffraction technique. Combination of representation analysis and Rietveld refinement reveals that a very rare structure, i.e., a quasi-120\u00b0 structure with $${\\boldsymbol{k}}_{2{\\mathrm{D}}}$$<\/jats:tex-math>\n \n \n k<\/mml:mi>\n <\/mml:mrow>\n \n 2<\/mml:mn>\n \n D<\/mml:mi>\n <\/mml:mstyle>\n <\/mml:mrow>\n <\/mml:msub>\n <\/mml:math><\/jats:alternatives><\/jats:inline-formula>\u2009=\u2009(1\/2, 0), is realized at the base temperature. The classical calculation of the phase diagram elucidates that CsCrF4<\/jats:sub> is the first experimental realization of the KT lattice having ferromagnetic Kagome bond. A single-ion anisotropy and Dzyaloshinskii-Moriya interaction play key roles in the selection of the ground state. Furthermore, a successive phase transition having an intermediate state represented by $${\\boldsymbol{k}}_{2{\\mathrm{D}}}$$<\/jats:tex-math>\n \n \n k<\/mml:mi>\n <\/mml:mrow>\n \n 2<\/mml:mn>\n \n D<\/mml:mi>\n <\/mml:mstyle>\n <\/mml:mrow>\n <\/mml:msub>\n <\/mml:math><\/jats:alternatives><\/jats:inline-formula>\u2009=\u2009(1\/3, 1\/3) is observed.
