Claims

[Claims for Utility Model Registration] A vane seal that is fitted inside an appropriate number of slits provided in a rotor or housing and slides freely in the radial direction, the slits having a straight groove in the axial direction; A bent groove section is formed by bending both ends of the straight groove section at right angles in the radial direction. A vane seal main body is provided which is gate-shaped and has a substantially rectangular first notch formed at the tips of the left and right side parts, and the vane seal main body has the linear part corresponding to the linear groove part and The left and right sides are disposed on the slit opening side so that the left and right sides correspond to the bent grooves, and a second notch is formed so as to be aligned with the first notch of the vane seal body. A pair of sealing members having a generally L-shaped overall shape are provided, and the sealing members are fitted into the inner part of the bent groove in alignment with the left and right sides of the vane seal body, and further, the pair of left and right sealing members have a generally L-shaped overall shape. interposing a letter-shaped elastic body in such a way that a corner portion abuts a joint between the straight groove portion and the bent groove portion, and a corner portion abuts a corner portion of the substantially gate-shaped vane seal body, and interposing a resilient member between the bottom of the linear groove and the linear portion of the vane seal body;
A vane seal configured to elastically bias the vane seal body in a radial direction.
