Abstract

A rectifying section 48 is disposed between a medicine atomizing means and a nozzle. Said rectifying section 48 has a flange portion 48a fitted to the upper end side of said atomizing means, a guide cylindrical section 48b integrally provided on the inner circumference of said flange portion 48a, a dome section 48c fixed on the inner circumferential face of said guide cylindrical section 48b, and a pair of slit holes 48d installed at the corresponding position of the guide cylindrical section 48b. Said dome section 48c is composed of a largespherical section 481c and a small-spherical section 481b, wherein the large-spherical section 481c is disposed on the center axis of the guide cylindrical section 48b and is formed with a diameter by which the outer circumferential edge thereof is spaced from the inner circumferential face of the guide cylindrical section 48b. The dome section 48c is supported by a pair of stays 48e of which the two points thereof opposite each other extend in the tangential direction, wherein a slit hole 48d is provided there. Furthermore, a pair of wall sections 48f positioned forward of the slit hole 48d are provided between the large-spherical section 481c and the guide cylindrical section 48b in the axial direction of the guide cylindrical section 48b so as to be directed in the diametrical direction of the large-spherical section 481c.
