PROBLEM TO BE SOLVED: To prevent slip-out of a groove sash roller on the door front side of a sliding gate from a V-shaped guide rail, when a sliding door main body of the sliding gate receives wind pressure. SOLUTION: When a sliding door main body 1 of a sliding gate is closed, slip-out preventive blocks 7 are set on both front and rear sides of a guide rail 3 so as to conform to a groove sash roller 4 on a door front side, and a sash roller abutting portion 8 of each block 7 functions to restrain the groove sash roller 4 from sliding in a guide rail 3 crossing direction and from rotating in the crossing direction in the sliding state. Furthermore, an inverted L-shaped step portion 11 of each block 7 functions to restrain the groove sash roller 4, assuming a mounted position on and engaged with the guide rail 3 from being turning, and urges the sliding door main body 1 to restore to its normal position by its weight as it, to thereby prevent slip-out of the groove sash roller 4.
