We construct classical solutions of open string field theory which are notinvariant under ordinary twist operation. From detailed analysis of the modulispace of the solutions, it turns out that our solutions become nontrivial atboundaries of the moduli space. The cohomology of the modified BRST operatorand the CSFT potential evaluated by the level truncation method stronglysupport the fact that our nontrivial solutions correspond to the closed stringvacuum. We show that the nontrivial solutions are equivalent to the twist evensolution which was found by Takahashi and Tanimoto, and twist invariance ofopen string field theory remains after the shift of the classical backgrounds.Comment: 19 pages, 2 figures; v2: errors fixe
