PROBLEM TO BE SOLVED: To provide a traveling carriage having a function of preventing a mount from falling due to wire cutting or the like when the carriage is moving on an inclined portion, without any problems when the traveling carriage moves along a horizontal portion, and further provide a wire connection portion that allows an easy field application and that can pass a sheave smoothly, in a stair lift device having a traveling carriage that goes along a rail in a stair hall of a building having several stories. SOLUTION: This stair lift device has the following configuration. A traveling carriage 4 is linked to a wire 15. The traveling carriage 4 includes an operation arm 32 that detects wire cutting or lowering of wire tractive force, a piston 30 that moves up/down in conjunction with the operation arm 32, inclination interlock means for detecting that the traveling carriage 4 is running on an inclined portion, and a cylinder 24 that operates according to the movement of the inclination interlock means. In a state where the operation arm 32 detects lowering of the wire tractive force, and only when the inclination interlock means detects that the carriage is running on the inclined portion, a brake plate 31 that is mounted on the upper portion of the piston is pressed on the under surface of a rail, and the friction force that is generated then makes the travel carriage stop.
