1. A guide device for a sliding door, comprising:
a base seat extending in a first direction, and formed with at least one guide groove that extends in a second direction transverse to the first direction; and a pair of side wall units, each of which includes a rigid sidewall piece coupled to said base seat, movable relative to said base seat in the second direction, and having at least one guide leg that engages slidably with said at least one guide groove, said rigid sidewall pieces of said side wall units defining a gap therebetween, and a positioning element mounted to one of said rigid sidewall piece and said base seat, and abutting releasably against the other one of said rigid sidewall piece and said base seat for locking said rigid sidewall piece to said base seat and fixing a width of said gap in the second direction; wherein said at least one guide groove includes three guide grooves being respectively a pair of end guide grooves that extend in the second direction and that are spaced apart from each other in the first direction, and a central guide groove that extends in the second direction and that is disposed between said end guide grooves; wherein said rigid sidewall piece of each of said side wall units includes a pair of guide legs, said guide legs of said rigid sidewall piece of one of said side wall units engaging slidably and respectively said central guide groove and one of said end guide grooves, said guide legs of said rigid sidewall piece of the other one of said side wall units engaging slidably and respectively said central guide groove and the other one of said end guide grooves;wherein said positioning element of each of said side wall units is mounted to said base seat and abuts releasably against one of said guide legs; and
wherein said base seat has a pair of end faces spaced apart from each other in the first direction, and a pair of side faces connected to said end faces and spaced apart from each other in the second direction, said end guide grooves extending through said side faces and respectively being disposed proximate to said end faces, said central guide groove extending through said side faces, each of said end faces being formed with a threaded hole that is in spatial communication with the respective one of said end guide grooves, said positioning element of each of said side wall units extending threadedly into said threaded hole of a corresponding one of said end faces. |
