Therefore, when assembled as shown in FIG. 4, the upper and lower end portions of the shim plate 27 that protrude from the assembly portion where both the assembly surfaces overlap with each other become the identification portions 271 and 272. Since the identification portions 271 and 272 enter the eyes of the operator when the assembly portion of the bearing member 22 is viewed from the front, the presence of the shim plate 27 can be confirmed by the operator.
  • the conventional assembly structure has a configuration in which a shim plate having a size obtained by cutting out the identification portions 271 and 272 is used, and the shim plate itself is actively hidden so as not to be seen from the outside. For this reason, there are cases where the operator who performs maintenance cannot recognize the existence of the ultrathin shim plate 27 of several tens of ⁇ m. Then, the shim plate 27 may be removed at the time of disassembling work, and it may be lost without being aware of it, or may be accidentally damaged. In such a case, in the adjustment work performed after the maintenance, the measurement must be performed again and the shim plate 27 having an appropriate thickness must be selected. In other words, the work man-hours increased.
  • the shim plate 27 used in the present embodiment is extremely thin, and the thickness cannot be recognized visually when the shim plate 27 is replaced. Therefore, it is necessary to perform measurement work using a micrometer each time, and this also increases the number of work steps. Although it is conceivable that the thickness information is marked on the shim plate 27, there is a limit to the thickness in order to mark the thin plate in units of microns. Further, when the bolt hole is formed as in the present embodiment, the marking portion may be lost. And, of course, the plate thickness cannot be confirmed in the used state.
  • the shim plate 27 of the present embodiment has a configuration in which the plate thickness information is displayed on the newly provided identification portion 272.
  • FIG. 5 shows an example in which a small hole 275 is formed in the identification portion 272.
  • the plate thickness is indicated by the number of the holes 275.
  • the shim plate 27 of the present embodiment can be confirmed to have a plate thickness of 20 ⁇ m by providing two holes 275. And if there is one hole 275, it can be seen that the thickness of the shim plate is 10 ⁇ m.
  • the identification portions 271 and 272 of the shim plate 27 protrude from the assembly portion of the bearing member 22 where the mounting portion 251 of the housing 25 and the fixing portion 501 of the column 5 overlap each other. Even the shim plate 27 can be easily recognized by the operator. Moreover, the thickness of the shim plate 27 can be easily grasped by providing the identification portion 272 with a shape feature relating to the thickness information. Further, since the shim plate 27 is entirely overlapped with the assembly surface 502 on the column 5 side, only the identification portions 271 and 272 of the shim plate 27 do not pop out and are damaged by bending or the like. Can be avoided.
  • the shape feature related to the thickness information given to the shim plate 27 is the hole, but other shapes such as a small notch in the identification portion may be used.
  • the attachment part 251 is formed smaller than the fixing
