The pusher 34 is formed with inclined surfaces (trapezoidal slope portions) 34 a that narrow toward the front side on both sides, and the inclined surfaces 34 a are formed along the inside of the regulating surface 27 a of the base end portion 27. The rear end side of the pusher 34 is disposed on the front side of the rear column 11, and the lateral width is larger than the length between the rear columns 11, and the rear column 11 regulates the retracted position of the pusher 34 (see FIG. 6).

The push button 35 is formed to extend upward from the rear end side of the pusher 34, and is positioned higher than the rear column 11. The lateral width is equal to the length between the shoulder portions 20 of the upper and lower holding plates 6 and 7 (that is, the width of the recess 23), and the push button 35 is guided between the recesses 23 and slides in the front-rear direction together with the pusher 34. .
At the forward movement position of the push portion 4, the pusher 34 is brought into contact with the stopper portion 27 b formed on the base end portion 27 of the pressing arm 30 as a stopper.
However, the forward position of the bush portion 4 may be adjusted so as to form a clearance of 2 to 3 mm so that the pressing portion 32 of the pressing arm 30 is not completely in contact with each other to form a flow path for the contents. It is preferable (the same applies to other examples described later).

[Mounting structure]
As shown in FIGS. 3 and 8, the mounting portion 2 is for mounting the pouch attachment 1 on the pouch 50, and includes a fixed plate 22 and a peristaltic pressing plate 42. As described above, the flat plate-like fixing plate 22 extending in the vertical direction is fitted into the long hole 21 (FIG. 6) formed in the lower holding plate 7 and fixed to the frame body 5.
A pair of cylindrical fixed holding pins 40 are vertically provided on the front surface of the fixed plate 22 with a space therebetween in the vertical direction. A diameter-enlarged portion 40 a having a diameter that is one size larger is formed at the distal end portion of the fixed holding pin 40.
