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.
In addition, if the position of support bar 10 is limited on the assigned position of axial S0 of mounting bracket 11, first end face 24 of seal 13 also can not be connected on the first madial wall 15b of embedded hole 15 of mounting bracket 11 so, and the end face 10b of the downside of support bar 10 also can not be connected on the connecting portion 21 of seal 13.
In above-mentioned example, be provided with two first raised lines 23, but also can be provided with more than or equal to three or only be provided with one, as long as be provided with one at least.Equally, in above-mentioned example, be provided with three second raised lines 26, but also can be provided with more than or equal to four, be provided with two or only be provided with one, as long as be provided with one at least.In addition, can in the claim scope of claims record, carry out various design alterations.
