<p>PROBLEM TO BE SOLVED: To provide a chair capable of inhibiting displacement of an upholstery material triggered by slide of a cushion material, while employing a structure of turning back a peripheral edge part of the upholstery material to the back side of a base, drawing the peripheral edge in the inner peripheral side of the base, and locking it to the base.SOLUTION: A protrusion part 28 that protrudes in a direction crossing with a surface direction of a back plate 11 and locking a cushion material 12 is formed on the outer peripheral edge part of the back plate 11. The protrusion part 28 regulates the slide of the cushion material 12 and inhibits the displacement of an upholstery material 13 triggered by the slide of the cushion material 12.</p> |
