Claims

[Scope of utility model registration request]

A roller type slide rail in which rollers are provided on each of the first rail and the second rail, and both rollers are slidably engaged with the roller tracks of the opposing rail, so that both rails extend and contract via both rollers. An elastic ring that expands and contracts in the radial direction is provided on the circumferential surface of the roller, and a narrow track section that narrows the interval between the roller tracks of the second rail is provided on the second rail, and the narrow track section is provided with the first rail.
A brake device for a roller type slide rail configured to compress and deform an elastic ring on the circumferential surface of the roller by pressurizing the rollers of the rail to brake expansion and contraction of the first rail.
