- the force applied to the inner surface of the case 10 of the follower 5 and the force per unit area (F ′) are reduced. Therefore, the follower 5 can be prevented from peeling from the follower auxiliary member 71, and the rigidity can be increased without being deformed even under severe conditions. As a result, it is possible to easily improve the vibration characteristics without changing the filling rate of the liquid fuel 4.
- the concave portion 13 and the convex portion 14 formed on the inner peripheral surface of the case 10 and the concave portion 74 and the convex portion 75 formed on the outer peripheral surface of the follow-up auxiliary member 71 are rectangular, but the concave portion 13 on the case 10 side As long as the convex portion 75 on the tracking auxiliary member 71 side, the concave portion 74 on the tracking auxiliary member 71 side, and the convex portion 14 on the case 10 side squeeze each other, the shape is not limited to a rectangular shape, and may be a mountain shape. Les.
- the effective contact area (S) between the follower 5 and the inner peripheral surface of the case 10 and the outer peripheral surface of the follower auxiliary member 71 may be increased, the inner peripheral surface of the case 10 and the follower auxiliary member It is sufficient that at least one of the inner peripheral surface of the case 10 or the outer peripheral surface of the follow-up assisting member 71 has a comb-teeth shape.
- packaging process of the packaging materials 9 and 109 is not limited to the process described above.
- the present invention by increasing the effective contact area between the follower and the fuel container or the follower and the follower auxiliary member, it is possible to suppress deformation of the follower and improve the vibration characteristics.
