Abstract

The present invention provides a leaf seal device which is available to assemble easily and to control and to set an inclination angle and a space of a sealing section. In the leaf seal device of the present invention, a connection holding section 21 of a sealing plate 12 is bent at a first bending section 22. Thereby, since laminated a plurality of sealing plates 12 are engaged sequentially at the first bending section 22, a radial direction is defined so as to become easily assemble. Also, according to inclining a face 24 at an inner circumferential side of the connection holding section 21, a pitch and a space of a sealing section 31 are changed. Therefore, the space of the sealing section can be controlled, if controlling a bend angle of the first bending section 22.
