The enclosed fluid supplied to the cylindrical base body flows out between the seal member and the outer peripheral surface of the cylindrical base body, and enters the bag-shaped portion of the seal member. As a result, the seal member swells due to the pressure of the enclosed fluid,
The bag-shaped portion comes into close contact with the inner surface of the slit nozzle, and the C-shaped packing is pushed out in the radial direction to come into close contact with the inner surface of the manifold, so that the movement of the coating liquid is restricted at the position of the seal member. When changing the coating liquid discharge width, the pressure of the enclosed fluid is released. As a result, the seal member contracts and the seal member is free to move. Therefore, by moving the enclosed fluid supply pipe along the manifold, it is possible to move the seal member and adjust the coating liquid discharge width.

Then, the seal plate swells due to the pressure of the coating liquid and adheres to the inner surface of the slit nozzle. Further, the elastic ring is spread outward by the pressure of the coating liquid, and the seal member is brought into close contact with the inner surface of the manifold at this position, so that the movement of the coating liquid is restricted. When changing the coating liquid discharge width, the supply of the coating liquid is stopped. As a result, the close contact between the seal member, the manifold, and the slit nozzle is released, and the position of the seal member can be adjusted by operating the rod and the coating liquid discharge width can be adjusted.

あってもよい。In the die coater 1 having the above structure, the enclosed fluid W having a pressure substantially equal to the supply pressure of the coating liquid P is supplied to the cylindrical substrate 11 of the adjusting device 10 through the enclosed fluid supply pipe 14. The enclosed fluid W is preferably the same as the solvent used for the coating liquid P. This is because even if a small amount of solvent leaks,
This is because it does not adversely affect the surface coated with the coating liquid. However, when a solvent is used as the enclosed fluid W, the C-type packing 28
Must use solvent resistant resin such as fluororesin. Further, the enclosed fluid W is not limited to a liquid and may be a gas.

Seal member non-welded portion 2 covering the hole 12 through the hole 12.
It flows out between 7, 27 and the cylindrical substrate 11 and enters the bag-shaped portion 26 of the seal member 23. As a result, the bag-like portion 26 and the non-welded portion 27 of the seal member 23 swell due to the hydraulic pressure of the enclosed fluid W. As a result, the bag-shaped portion 26 comes into close contact with the upper surface and the lower surface of the slit nozzle 5. Also, the non-welded part 2
A packing 28 that covers 7, 27 spreads in the radial direction and comes into close contact with the inner surface of the manifold 3. Since the ends of the C-shaped packing 28 are sealed by the packings 30 and 30, the enclosed fluid W does not leak from between the C-shaped packing 28 and the cylindrical base 11.
