Abstract
A two-stage linked sliding door of a machine tool is provided with a first door half and a second door half movable through different strokes. Pulleys are disposed individually at two opposite end portions of the second door half, and a wire is stretched between the pulleys. The opposite end portions of the wire are secured to the door frame or the first door half by two wire tensioning springs, individually, such that the opposite end portions face each other. These two springs are juxtaposed and offset with each other so that their respective central axes do not line on the same axis.

A two-stage linked sliding door of a machine tool, comprising:
- a two-stage sliding door attached to the machine tool, the sliding door comprising a first door half movable through a predetermined stroke and a second door half movable through a stroke shorter than that of the first door half and accommodated overlapping a fixed cover of the machine tool;
- two pulleys disposed individually at one and the other end portions of the second door half;
- a wire stretched between the two pulleys;
- a wire tension portion which secures the opposite end portions of the wire to one of a door frame and the first door half through two elastic members individually pulling the opposite end portions of the wire in a manner such that the opposite end portions of the wire face each other;
- and
- a wire intermediate portion fixing member which secures an intermediate portion of the wire between the two pulleys to the other of the door frame and the first door half, wherein
- the two elastic members are juxtaposed and offset with each other so that the respective central axes thereof do not lie on the same axis.
