To provide a table attaining the firm attachment of legs to a top board in spite of a compact configuration.

A table includes: recessions 12 arranged in a top board 1; projections 22 arranged in legs so as to be inserted to the recessions 12; and fixing mechanisms for fixing the projections 22 inside the recessions 12. The fixing mechanisms include tension members 130. Each tension member 130 is configured to selectively obtain a lock state (P) where the member performs tension between a slid contact surface 12d and a pressurized surface 22d so as to fix the projection 22 inside the recession 12 and a lock release state where the member cancels the tension posture so as to permit the projection 22 to be separated from the recession 12.
