Lining shown in Fig. 3 (a) and (b) is that outer peripheral face is processed smoothly, and making maximal roughness is the situation about Rmax1.5 μ m.That is, illustration is used for the common lining that recess is not set of optical receptacle on outer peripheral face.
Shown in Fig. 2 (a), Fig. 3 (c), lining 3 has the groove shape recess 3c that makes progress in week that is arranged on outer peripheral face 3b.
That is, the portion of being pressed into and recess 3c on the outer peripheral face 3b of lining 3, have been arranged alternately vertically.
And the outer peripheral face 3b of lining 3 is provided with at least 2 and is pressed into portion and is arranged on 2 groove shape recess 3c that are pressed between the portion.
This groove shape recess 3c for example can form through the cut method.
And making recess 3c is when forming loop-like groove, can form at least 1 not at the open-ended recess 3c of lining 3.
If form this recess 3c, automatically form suitable chimeric size through cutting the outer peripheral portion that is adjacent to recess 3c when then being pressed into, therefore, the state that is pressed into that can realize ideal.
At this moment, be pressed into the axial dimension W of portion when excessive outer peripheral portion become and be not easy to cut, therefore, bite phenomenon.In contrast, be pressed into the axial dimension W of portion when too small outer peripheral portion excessively cut and chimeric size decreases, keep intensity a little less than, might become comes off easily.
Therefore, the axial dimension W that is pressed into portion is preferably below the above 0.13mm of 0.02mm.
And being more preferably the axial dimension W that makes the portion of being pressed into is below the above 0.11mm of 0.03mm.
And, spacing dimension between the part of recess 3c is not set promptly is pressed into the spacing dimension P of portion when insufficient, cross recess 3c and disturb because of cutting overlap that outer peripheral portion produces with the adjacent portion of being pressed into, might hinder happy being pressed into.And, if fully guarantee the spacing dimension P of the portion that is pressed into, then can carry out taking in, keeping of chip 14 more effectively, therefore, can suppress because of producing the dirt that dust etc. causes.
Therefore, the spacing dimension P that is pressed into portion is preferably more than the 0.05mm.
And the height dimension H of recess 3c (with the size of the direction of axial quadrature) is preferably more than the 4 μ m.
Shown in Fig. 2 (b), Fig. 3 (d), lining 13 is provided with a plurality of recess 13c that the bottom outlet shape is arranged with being spaced from each other on outer peripheral face 13b.That is, the portion of being pressed into and recess 13c on the outer peripheral face 13b of lining 13, have been arranged alternately vertically.
At this moment, recess 13c both can be provided with shown in Fig. 2 (b) regularly, also can shown in Fig. 3 (d), be provided with brokenly.
The recess 13c of rule for example can form through etching method.Irregular recess 13c for example can form through the barreling method.In addition, the hole 13a that runs through the center vertically can be the same with the hole 3a of aforesaid lining 3, and material also can be the same with aforesaid lining 3.That is, only the form of recess is different for lining 3 and lining 13.

Therefore, preferably through recess 13c is set, the outer peripheral face maximal roughness that makes lining 13 is more than the Rmax4 μ m.
But, needn't be necessarily the recess 13c of formation rule clearly, above as long as the outer peripheral face maximal roughness of lining 13 is Rmax4 μ m.
Fig. 4 is the mode chart of the effect when being used for illustration and being provided with recess.
In addition, as an example, the effect the when outer peripheral face of lining 3 is provided with recess 3c is carried out illustration at this.
Shown in Fig. 4 (a), when lining 3 was pressed into the 2e of hole portion of housing 2, shown in Fig. 4 (b), the interior circumferential portion of the 2e of hole portion of the outer peripheral portion of lining 3, housing 2 was cut and the part that becomes chip 14 is incorporated in the inside of recess 3c.At this moment, because chip 14 is maintained at the inside of recess 3c, therefore shown in Fig. 4 (c), can suppress to become overlap and give prominence to, or bulk storage goes out chip 14.At this moment, in the front that is pressed into direction of lining 3, the interior circumferential portion of the 2e of hole portion of the outer peripheral portion of lining 3, housing 2 is cut, and therefore, then the amount of cutting is few more towards rear end side more.Therefore, can not make overlap outstanding from the rear end side that is pressed into direction of lining 3, or bulk storage go out chip 14.
This effect can't obtain in patent documentation 1, patent documentation 2 disclosed technology.
For example; In patent documentation 1 disclosed technology; Disclose on the cross section of the direction vertical with being pressed into direction the lining (serve as protuberance tube portion 92 in the patent documentation 1) that is provided with the prominent shape of a lot of gears with radial, the part that is become chip but the interior circumferential portion of the hole portion of the outer peripheral portion of lining, housing cuts is by bulk storage extremely outside (for example with reference to Fig. 4 of patent documentation 1, Fig. 5, [0023] paragraph, [0024] paragraph etc.).At this moment, the interior circumferential portion of the outer peripheral portion of lining, housing bore portion is cut and the part that becomes chip also might become overlap and give prominence to.
And in patent documentation 2 disclosed technology, the end that discloses inner peripheral surface is provided with the lining of flash gutters (being pedestal 7 in the patent documentation 2).But, in this technology, if it is outstanding to suppress overlap when being pressed into, also can't change become chip part by bulk storage to outside.
And in patent documentation 1, patent documentation 2 disclosed technology, the minimizing of stating after also can't obtaining is pressed into load, reduce be pressed into load uneven, reduce the effect that is pressed into position dimension inequality (raising is pressed into positional precision) etc.

In addition, as previously mentioned, maximal roughness is that the situation of Rmax1.5 μ m is the situation that recess 13c is not set.
Table 2 is the charts of having concluded data shown in Figure 11.
Table 2
Can know according to Figure 11, table 2,, the size that is pressed into load is changed with uneven if the outer peripheral face maximal roughness is changed.
At this moment, increase outer peripheral face maximal roughness (surfaceness is thick more) more, it is more little then to be pressed into load, the uneven tendency that diminishes that also is in.
In addition, as previously mentioned, the outer peripheral face maximal roughness that is provided with recess 13c is preferably more than the Rmax4 μ m, also can know this situation according to the data shown in Figure 11, the table 2.
Figure 12 is used for the illustration magnitude of interference and the plot that is pressed into the relation of load.
In addition, Figure 12 is used for the illustration magnitude of interference and the plot that be pressed into the relation of load relevant with being provided with a plurality of lining that bottom outlet shape recess 13c arranged 13 as an example.
" ◆ " among the figure is the situation that the lining of recess is not set on the outer peripheral face; " ■ " is that the outer peripheral face maximal roughness is the situation of Rmax6 μ m; " ▲ " is that the outer peripheral face maximal roughness is the situation of Rmax4 μ m, and " ● " is that the outer peripheral face maximal roughness is the situation of Rmax3 μ m.
And Figure 12 (a) is that the scope of the magnitude of interference is the situation till the 0.012mm, and Figure 12 (b) is that the scope of the magnitude of interference is the situation till the 0.03mm.
Can know according to Figure 12 (a) and (b),, then can improve the value of the magnitude of interference,, also can reduce to be pressed into load even perhaps increase the scope of the value of the magnitude of interference if recess 13c is set.And, can also reduce to be pressed into the inequality of load.
At this moment, be more than the Rmax4 μ m if make the outer peripheral face maximal roughness, then can improve the value of the magnitude of interference, even perhaps increase the scope of the value of the magnitude of interference, also can reduce to be pressed into load more.And, can also reduce to be pressed into the inequality of load more.
