Further, the screw S abuts against the shaft 41 whose tip is inserted into the recess 234 and presses the shaft 41 against the inner wall of the recess 234, thereby fixing the shaft 41 to the cap 23.

  The appearance change applying unit 3 will be described with reference to FIG. In the present embodiment, the appearance change imparting unit 3 is a coloring unit 3A that colors the level indicator 100. The coloring unit 3A includes a printing unit 31, an occlusion body 32, a frame 33, a pressing member 34, and a protective cap 35. As coloring means 3A, it is possible to use, for example, a penetration mark such as Shachihata (registered trademark) or a marking pen.

  The printing unit 31 has a seal surface 311 in contact with the level indicator 100. A through hole 312 is formed at the center of the printing unit 31. The printing unit 31 is made of, for example, porous rubber. The storage body 32 is made of, for example, a sponge, and absorbs and holds a coloring substance containing a coloring component. The printing unit 31 and the storage member 32 are accommodated in the frame 33 in a state where the storage body 32 is in contact with the opposite side of the printing surface 311 of the printing unit 31, and the frame 33 is held in the holding unit 21. There is. A coloring substance is supplied to the printing unit 31 from the storage 32, and the printing unit 31 gives the level indicator 100 a colored mark such as a character, a figure or a symbol. The coloring substance is not particularly limited as long as it can color the level indicator 100. For example, an aqueous or oil-based ink can be used. The color of the colored substance is preferably not the same as that of the level indicator 100.

  The distance L between the lower end of the holding portion 21 (indicated by a broken line in FIG. 2C) and the marking surface 311 of the printing portion 31 is the distance L between the first display portion 103 and the second display portion 104 It is set below the interval. Therefore, as shown in FIGS. 3B and 3C, when the engaging portion 22 is inserted between the two first display portions 103, the seal surface 311 is the second display portion 104 (the top of the level display tool main body 101 It is supposed to contact).

  The pressing member 34 is disposed above the storage body 32 and is held in the holding portion 31. A through hole 341 is formed in a portion of the pressing member 34 disposed immediately above the storage body 32. When the cap 23 is removed from the holding portion 21, a part of the storage body 32 is exposed from the through hole 341. The storage material 32 can be replenished with a coloring substance via the through hole 341.

  The protective cap 35 is placed on the side of the seal surface 311 of the printing unit 31, and is partially detachably accommodated in the holding unit 21. The protective cap 35 protects the seal surface 311 from dryness and dirt.

As described above, the shaft 41 inserted into the recess 234 is fixed to the cap 23 by the screw S (see FIG. 2C). As a result, the shaft 41 and the cap 23 (body part 2) are connected non-rotatably and detachably with each other. The other end of the shaft 41 is fixed to the handle 43 so as not to be relatively rotatable, and as the handle 43 rotates, the shaft 41 also rotates.

[Method of using adjuster and function and effect]
When using the adjuster 1, first of all, the protective cap 35 is removed. Next, as shown in FIGS. 3B and 3C, the engaging portions 22 are respectively inserted between the two first display portions 103 of the level indicator 100. At this time, the lower end of the holding unit 21 contacts the upper surface of the first display unit 103 (see FIG. 3C), and the seal surface 311 of the printing unit 31 contacts the second display unit 104. When the handle 43 is rotated, the shaft 41 is rotated. With the rotation of the shaft 41, the main body 2 is rotated and the engaging portion 22 contacts the first display portion 103 to rotate the level indicator 100. Thereby, the height of the level display tool 100 can be adjusted, and the 1st display part 103 and the 2nd display part 104 can be adjusted to target height. As shown in FIG. 3D, a colored mark M is provided to the second display portion 104 of the adjusted level indicator 10 by the printing portion 31 of the coloring means 3A. From this mark M, it can be determined that the level indicator 100 has been adjusted.

  When the lower inner surface of the engagement portion 22 has the first guide surface 221, when the engagement portion 22 is inserted between the two first display portions 103, it can be smoothly inserted. Moreover, when the lower part of the engaging part 22 has the 2nd guide surface 222, when inserting the engaging part 22 between two 1st display parts 103, it can insert smoothly.

Second Embodiment

  FIGS. 4A and 4B are partial longitudinal sectional views of the main body 2. The appearance change giving unit 3 in the second embodiment is a shape change giving means 3B for changing the shape of the level indicator 100.

  The shape change giving means 3 B is provided with a notch forming means 36, and the notch forming means 36 is held by the frame 33. The notch forming means 36 is not particularly limited as long as the notch can be formed at a position visible to the outside of the level indicator 100, for example, a needle (see FIG. 4A). A blade or the like (see FIG. 4 (b)) can be used. The distance L between the lower end (shown by a broken line in FIGS. 4A and 4B) of the holding portion 21 and the lower end of the notch forming means 36 is the first display portion 103 of the level indicator 100 and The distance between the second display unit 104 and the vertical direction is smaller than that of the second display unit 104. Therefore, when the engaging portion 22 is inserted between the two first display portions 103, the notch forming means 36 is in contact with the second display portion 104. Thereby, a notch such as a hole or a scratch is formed as a mark M in the second display portion 104 of the level indicator 100 after adjustment, and the surface shape of the second display portion 104 is different from the surface shape before adjustment . From this mark M, it can be determined that the level indicator 100 has been adjusted.

<Modification>
Below, the modification of the adjuster 1 is demonstrated. The same components as those described above are denoted by the same reference numerals, and description thereof is omitted, and differences will be mainly described. The following modifications may be combined as appropriate.

[Modification 1]
The appearance change applying unit 3 may be detachably held by the main body 2. That is, in the coloring unit 3A, the printing unit 31, the storage member 32, the frame 33 for storing them, and the pressing member 34 may be detachably held by the holding unit 21. Further, in the shape change applying means 3B, the notch forming means 36, the frame 33 for holding it, and the pressing member 34 may be detachably held by the holding portion 21.
