PURPOSE:To increase the displacement of a compressor by forming an arc- shaped cut on the back part of an escape hole of a vane of a cylinder, thereby easing a bending angle limit of a formed part on the vane side of a C-shaped vane spring as well as increasing the vane stroke. CONSTITUTION:On the back surface of an escape hole 19 of a vane groove 21 of a cylinder 14 in which a vane 16 is inserted, is formed an arc-shaped cut 20. Accordingly it becomes possible to decrease the bending angle of a formed part 22 on the vane 16 side of a C-shaped vane spring attached on the back part of the vane 16 for depressing the vane 16 without causing the spring to contact with the cylinder 14, which makes it possible to increase the displacement of a compressor by increasing the vane stroke. |
