2. Description of the Related Art Conventionally, as shown in FIG. 9, for example, as shown in FIG. 9, an ejector capable of switching jet flow has a switching shaft 3 attached to a stem 2 protruding from a container 1, and an operation button 4 attached to the switching shaft 3. There is a cover which is attached so as to be rotatable around the switching shaft 3.

A jet passage 4a is formed laterally in the operation button 4, a spring 5 is put in the jet passage 4a, a center post 6 is put in, and then a nozzle member 7 having a cap shape is press-fitted and jetted. The opening of the passage 4a was blocked.
Further, the cam portion 3a at the tip of the switching shaft 3 is inserted in the ejection passage 4a, and the tail end enlarged diameter portion 6a of the center post 6 is pressed against the cam portion 3a by the urging force of the spring 5.
(See Japanese Patent Laid-Open No. 2001-163379.)

In the non-use state, as shown in FIG. 10 (A), the center post 6 is returned by the cam portion 3a against the spring 5 by a half stroke, while the nozzle hole 7a of the nozzle member 7 is covered by the shoulder cover 8. The projection portion 4b is abutted against the abutting step portion 8b of the shoulder cover 8 and the operation button 4 is prevented from being pressed down.

When jetting a continuous linear flow, as shown in FIG.
As shown in (B), the cap cover 9 is rotated around the stem 2 in one direction. Then, the center post 6 is returned by the entire stroke against the spring 5, and the gap between the tip of the center post 6 and the inner surface of the top of the nozzle member 7 is widened.
It is possible to shift a from the shutter portion 8a and press the operation button 4. As a result, when the operation button 4 is pressed down, the content is continuously and straightly ejected from the ejection port 7a as a continuous linear flow.

[0006] When jetting a mist-like diffused flow,
As shown in (C), the cap cover 9 is rotated around the stem 2 in the other direction. Then, the center post 6 is pushed out by the spring 5 for the entire stroke, and the gap between the tip of the center post 6 and the inner surface of the top of the nozzle member 7 is narrowed.
It is possible to shift the shutter button 8a from the shutter portion 8a and push down the operation button 4. As a result, when the operation button 4 is pushed down, the contents are atomized and ejected as an atomized diffusion flow from the nozzle 7a through the spiral groove formed on the inner surface of the top of the nozzle member 7.

[0007]

However, since such a conventional ejector requires the center post 6 and the spring 5 and the cap cover 9 in addition to the shoulder cover 8, the number of parts is large. And the structure becomes complicated,
