Shown in Fig. 6 (a), the notch part 7A of lamp holder 4A is, form by the inclined plane of cylinder sides 5 to the notch part top, its inclined plane become from cylinder sides 5 to end face 6 chamferings of lamp holder 4A form bigger ungulate.Shown in Fig. 6 (d), this notch part 7A for example locatees with lug boss 22, the ring-type slot part 9a fastening mutually of the lamp holder maintaining part of being inserted in the maintaining part 24 of spring catch 25 and bulb socket 20 9, on direction of principal axis, temporarily fixed, so formation prevents the state that the end face 6 of lamp holder 4 separates from bearing surface 21 once more.Therefore, the middle body of notch part 7A becomes the location division, and lamp holder 4A installs with the state of locating on the circumferencial direction of bulb socket 20.In addition, can be form shown in 5 figure as lug boss 22 with notch part 7A correspondence, or truncated cone shape, or cylindrical shape.

As Fig. 6 (b), (c) shown in, when being installed in lamp holder 4A on the bulb socket 20 by this notch part 7A, even the lug boss 22 of the notch part 7A of lamp holder 4A and bulb socket 20 is not quite identical in the position of circumferencial direction, but owing to can pass through lug boss 22, along the inclined plane of notch part 7A, make lamp holder 4A can being directed, thereby also can easily install in the mode of circumferencial direction rotation.In addition, particularly since lamp holder 4A can move along the inclined plane of notch part 7A, so can suppress to install substantially the time to the impact of lamp 1.

In addition, the two side areas except that central authorities (at least a portion) on the inclined plane of notch part 7A or whole being implemented roughening such as ball blast (blast) processing processes, when the inclined plane that lug boss 22 and this are roughened processing contacts, translational speed on the circumferencial direction of lamp holder 4A is slack-off, so that the impact of lamp 1 is further reduced.

In addition, shown in Fig. 7 (a), the notch part 7B of lamp holder 4B can form, and is had to the position of end face 6 by cylinder sides 5: from cylinder sides 5 towards the central inclined plane 7a at breach top, left-leaning inclined-plane 7b and Right deviation inclined-plane 7b about it.Left-leaning inclined-plane 7b and the Right deviation inclined-plane 7b of notch part 7B form left-right symmetry, and different with angle of inclination and the incline direction of central inclined plane 7a.In addition, the central inclined plane 7a of notch part 7B plays the effect of location division here.

Such notch part 7B is owing to have left-leaning inclined-plane 7b and Right deviation inclined-plane 7b, thereby when shown in Fig. 7 (b)～(e), when on bulb socket 20, lamp holder 4B being installed, insert dearly along with lamp holder maintaining part 9 in the maintaining part 24 of bulb socket 20 (end face 6 is near bearing surface 21), one and lug boss 22 butts among left-leaning inclined-plane 7b or the Right deviation inclined-plane 7b, lamp holder 4B is moved along the inclined plane, this lug boss 22 is guided to the position of central inclined plane 7a.Therefore, when bearing surface 19 butts of the end face 6 of lamp holder 4B and bulb socket, make the position consistency of circumferencial direction by notch part 7B and lug boss 22.In addition, when making lamp holder maintaining part 9 enter in the maintaining part 24, even can not make notch part 7B and lug boss 22 in full accord in the position of circumferencial direction, but because notch part 7B is directed to lug boss 22, so the position reproduction of lamp 1 circumferencial direction is installed well.

Particularly, install via the lamp holder 4B below the lamp in the situation of lamp 1 at bulb socket 20, when the central inclined plane 7a that becomes notch part 7B location division and lug boss 22 were inconsistent in the position of circumferencial direction, lug boss 22 was supported the end face 6a of lamp holder 4B.In addition, lamp 1 is rotated at circumferencial direction, the right side of notch part 7B (left side) inclined plane 7b and lug boss 22 carry out contraposition at circumferencial direction, then become the state that lamp holder 4B side can move along right (left side) inclined plane 7b, are subjected to central inclined plane 7a guiding and move at the position of lug boss 22 lamp holder 4B.

Therefore, when notch part 7B and lug boss 22 are positioned, almost do not fall the impact that equates from the difference in height of lug boss 22, can reduce impact lamp 1 with lamp 1.In addition, if notch part 7B and lug boss 22 become the position location, bearing surface 21 butts of the end face 6 of lamp holder 4B and bulb socket 20 then, and as Fig. 7 (d), (e) shown in, be set at spring catch 25 fastenings in the maintaining part 24 in the ring-type slot part 9a of the lamp holder maintaining part 9 of lamp holder 4B, with respect to axially temporarily being fixed.Therefore, become under the situation of position location at notch part 7B and lug boss 22, the end face 6 that can prevent lamp holder 4B leaves from the bearing surface 21 of bulb socket 20.Therefore, in case notch part 7B and lug boss 22 are set in the position location, bulb socket 20 and lamp holder 4B be because the position relation of the position consistency of circumferencial direction, and form the state that is stably installed.

In addition, implement roughening processing such as ball blast processing by surface to left-leaning inclined-plane 7b and Right deviation inclined-plane 7b, lamp holder 4B moves along lug boss 22, owing to left-leaning inclined-plane 7b or the Right deviation inclined-plane 7b of notch part 7B slows down slowly, can further reduce the impact of landing.

In addition, in lamp of the present invention, can also be for as Fig. 8 (a), (b) notch part of the lamp holder shown in.Fig. 8 (a) (b) is the stereogram of other form of indication notch portion.

Shown in Fig. 8 (a), the notch part 7C of lamp holder 4C is formed on from cylinder sides 5 to end face on 6 the position.This notch part 7C is forming square groove with predetermined length on the cylinder sides of the axis direction of lamp.By like this forming notch part 7C with predetermined length on the cylinder sides, thereby can be easier to visually judge that lug boss 22 enters notch part 7C and positions and whether finish.The groove shape of notch part 7D forms semicircle among Fig. 8 (b), has the identical effect with Fig. 8 (a).

More than, from Fig. 1 to Fig. 8 (a), (b), only (7A～7D) is arranged on lamp holder 4, and (structure at the place on the 4A～4D) is illustrated, yet this is when being specific direction to the direction of illumination that lamp 1 is limited at light to notch part 7.Therefore, the lamp with other direction of illumination also can be provided with lamp holder as shown in Figure 9.Fig. 9 (a)～(c) is the stereogram of other structure of configuration of notch part of the lamp holder of indication lamp.

When the direction of illumination of lamp 1 is 180 degree symmetries, shown in Fig. 9 (a), notch part 7 (7A～7D) also can be formed on the position of two equalizations.In addition, when the direction of illumination of lamp 1 is 120 degree symmetries, shown in Fig. 9 (b), notch part 7 (7A～7D) also can be formed on the position of three equalizations.In addition, when the direction of illumination of lamp 1 is 90 degree symmetries, shown in Fig. 9 (c), notch part 7 (7A～7D) also can be formed on the position of four equalizations.
