As shown in Figure 7, sub-assemblies 28 is assembled in the sub-assemblies 29.That is, first cylindrical portion 19 that is connected the seal 13 on signal lamp body 2 and the support bar 10 is embedded the embedded hole 15 of the mounting bracket 11 on the 5a of the portion of bearing of the end face 5 that is fixed on basic machine 4 from this inlet portion 18.With the periphery 10c of support bar 10 embed embedded hole 15 first among all 15a, be connected on the first madial wall 15b of embedded hole 15 up to first end face 24 of the downside that is positioned at seal 13.Make between the axis of each part 10,11,13 consistent with each otherly thus, interfix by mutual contraposition.
Like this, in the seal 3 of the signal lamp mounting structure 3 of this example, can utilize first raised line 23 of first cylindrical portion 19 to seal gap between seal 13 and the mounting bracket 11.In addition, can utilize second raised line 26 of second cylindrical portion 20 to seal gap between seal 13 and the support bar 10.Consequently, for example,, can prevent that also them from entering in through hole 3a, for example support bar 10 even water or other liquid enter the embedded hole 15 of mounting bracket 11 and the gap between the support bar 10 from the outside.Like this, can realize the signal lamp mounting structure 3 of good seal performance by using support bar 10, mounting bracket 11 and seal 13.In addition, by seal 13 is pulled down from this signal lamp mounting structure 3, just can constitute the signal lamp mounting structure of not considering sealing property.In other words, by on signal lamp mounting structure in the past, appending seal 13 of the present invention, just can improve sealing property.As the specification that possesses high sealing performance with do not consider the integral body of signal lamp mounting structure of the specification of sealing property, because can shared support bar 10 and mounting bracket 11 as main member, so can reduce manufacturing cost.
In addition, when not using seal 13 and filler 14, the end face 10b of the downside of support bar 10 is connected on the first madial wall 15b of mounting bracket 11.
In addition, owing to can seal the end face 10b of support bar 10 and the gap between the connecting portion 21 by connecting portion 21 as the step-like ring-type abutting part of seal 13 is connected on the end face 10b of downside of support bar 10, so can further improve the sealing property of signal lamp mounting structure 3.
In addition, owing to can be connected to the gap between first end face 24 of first cylindrical portion 19 of the first madial wall 15b that seals mounting bracket 11 on the first madial wall 15b of mounting bracket 11 and seal 13 by first end face 24 that makes seal 13, so can further improve the sealing property of signal lamp mounting structure 3.
In addition, because first raised line 23 is formed on vertically that S1 leaves on the position of connecting portion 21 predetermined distances, so can avoid embedding the inhibition of end face 10b that the strain of embedded hole 15 first raised line 23 when interior is subjected to the downside of support bar 10.Because first raised line 23 is strain reliably, so can keep the better seal performance.
In addition, first raised line 23 has can be at the free margins 23a of free displacement on the axial S1, and elastically deformable be the lateral attitude towards the anti-direction of insertion A2 inclination of embedded hole 15.Thus, first cylindrical portion 19 of seal 13 is easy to insert in the embedded hole 15.In addition, because first raised line 23 under the confined state can form the sealing lip that extends towards anti-direction of insertion A2, so can further improve sealing property for the outside of anti-direction of insertion A2.
Second raised line 26 has can be at the free margins 26a of free displacement on the axial S1, and elastically deformable be towards the lateral attitude with respect to the anti-direction of insertion B2 inclination of interior all 10d of support bar 10.Thus, second cylindrical portion 20 of seal 13 is easy to insert in the support bar 10.In addition, because second raised line 26 under the confined state can form the sealing lip that extends towards anti-direction of insertion B2, so can further improve sealing property for the outside of anti-direction of insertion B2.
In addition, can utilize two first raised lines 23 for example to carry out dual-seal, can further improve sealing property.In addition, can utilize three second raised lines 26 for example to carry out triple seal, can further improve sealing property.Like this, obtain the effect that can improve sealing property, have many first raised lines 23 to get final product, or have many second raised lines 26 also passable.
In addition, can be if first raised line 23 has at the free margins 23a of free displacement on the axial S1, so much first raised line 23 is preferably on the axial S1 and is configured with separating predetermined distance, and in addition, connecting portion 21 best and as abutting part axially is being configured on the S1 with separating predetermined distance.Thus, can guarantee the displacement of free margins 23a.For second raised line 26 too.
In addition, because second end face 27 of the upside of second cylindrical portion 20 of seal 13 extends to the top position above the inlet portion 18 of the embedded hole 15 of mounting bracket 11 always, so even for example mounting bracket 11 is not had by water logging, before the water surface reaches the height of second cylindrical portion 20, also can prevent entering of sealing so.
In addition, in the signal lamp 1 of this example, owing to can obtain effect, so can realize good seal performance, cheap signal lamp 1 based on above-mentioned seal 13.In addition, filler 14 is set preferably, thus, can further improves sealing property.
In addition, for this example, can consider following variation.In the following description, be that the center describes with the point different with above-mentioned example, identical structure indicates identical symbol, and omits explanation.
For example, fine if sealing property need not, second end face 27 of the upside of seal 13 also can be positioned at the below of inlet portion 18 of the embedded hole 15 of mounting bracket 11 so.In addition, it is also conceivable that and do not use filler 14.
First raised line 23 is not limited to above-mentioned shape, and for example, above-mentioned free margins 23a can not be the shape of above-mentioned lateral attitude in free displacement on the axial S1, non-strain also, particularly, also can be to be semicircular shape at unconfinement state lower section.Second raised line 26 too.
In addition, if first raised line 23 is a semicircular in shape at unconfinement state lower section, so also can consider to dispose in abutting connection with ground with connecting portion 21.In addition, if second raised line 26 is semicircular shape at unconfinement state lower section, so also can consider to dispose in abutting connection with ground with connecting portion 21.
