  However, in the conventional mounting structure for a road marking body as described in Patent Document 1, the base portion rotates with respect to the pole portion. If the base is rotated, the optical axis of the illuminant is shifted, and the effect obtained at the beginning of installation cannot be lost. there were.

  The present invention has been made in view of the problems as described above. In the road marking body in which the pole portion and the base portion are provided separately and fixed to the road surface using the bolt portion provided in the pole portion. An object of the present invention is to provide a road surface mounting structure for a road marking body in which the risk of rotation of the base portion is reduced.

  In order to achieve the above object, the present invention is configured as follows. That is, the road surface mounting structure of the road marking body according to the present invention is provided with a pole portion projecting from the lower end of the cylindrical portion and a bolt portion projecting downward from the lower end of the cylindrical portion, An anchor nut portion embedded in a road surface and screwed to the bolt portion; a large-diameter hole that opens upward and has a bottom portion; and a base portion provided with a small-diameter hole that penetrates the center of the bottom portion, The road surface mounting structure for a road marking body in which the tubular portion and the bolt portion are inserted into the hole, the bolt portion is screwed to the anchor nut portion, and the bottom portion is sandwiched between the pole portion and the road surface. And the outer surface of the said cylindrical part is elastically expanded toward the outer side, and is pressing the inner surface of the said small diameter hole, It is characterized by the above-mentioned.

  According to the road surface mounting structure of the road marking body according to the present invention, the outer surface of the cylindrical portion is configured to be elastically expanded so that the outer surface of the cylindrical portion presses the inner surface of the small-diameter hole. Even if a strong frictional force is generated between the inner surface of the hole and the pole portion and the base portion are provided separately, the risk of the base portion rotating can be reduced.

  In addition, the base portion is provided with a light emitter that is a light emitting diode, and the base portion is configured to emit light directly from the light emitter to the outside of the base portion. Since the part is prevented from rotating, it is preferable that the optical axis of the light emitter can be maintained in a predetermined direction and the effect obtained at the beginning of the installation can be maintained.

  Further, the road surface mounting method of the road marking body according to the present invention includes a bolt portion of a pole portion in which a cylindrical portion is provided to protrude downward from a lower end and a bolt portion is provided to protrude downward from the lower end of the cylindrical portion. Is inserted through a small-diameter hole in the base portion provided with a large-diameter hole that opens upward and has a bottom portion and a small-diameter hole that passes through the center of the bottom portion, and the bolt portion is screwed into an anchor nut portion embedded in the road surface. A road surface mounting method for a road marking body for attaching a pole portion and a base portion to a road surface, wherein the bolt portion is fastened to an anchor nut portion, and the outer surface of the cylindrical portion is elastically expanded outwardly to form a cylinder. The outer surface of the shaped portion is pressed against the inner surface of the small-diameter hole.

  According to the road surface mounting method of the road marking body according to the present invention, the bolt portion provided on the pole portion is screwed to the anchor nut portion embedded in the road surface, so that the pole portion and the base portion are simultaneously placed on the road surface. It can be attached, but by tightening the bolt part to the anchor nut part and pressing the outer surface of the cylindrical part against the inner surface of the small-diameter hole, strong frictional force is generated between the outer surface of the cylindrical part and the inner surface of the small-diameter hole. Even if the pole portion and the base portion are provided separately, the attachment to the road surface can be performed so as to reduce the risk of the base portion rotating.

  Further, the pole portion is provided with a step portion whose diameter is reduced in the middle in the vertical direction, a plurality of jig holes are opened on the upper surface of the step portion, and a through hole through which the pole portion can be inserted is provided. Using a mounting jig comprising a main body, a plurality of fitting portions projecting downward from the periphery of the through hole of the main body, and a handle portion provided integrally with the main body. If the fitting part is fitted and the pole part is rotated, the fitting part is fitted into all the plurality of jig holes to strengthen the tightening force by the handle part, and the cylindrical part is elastically expanded. This is preferable because it can be performed more reliably.

  Further, in the road marking body having the road surface mounting structure according to the present invention, the base portion is installed on the road surface of the road, and a light emitter is provided at at least one end in the longitudinal direction along the road, At least one end of the base portion is an outwardly convex R portion, and the R portion has a light emitting window portion for transmitting light emitted from the light emitter to the outside of the R portion. Preferably, the light emitting window is formed from the front side to the side of the light emitter.

  In the road marking body having such a configuration, the R portion, which is one end of the base portion, has a shape that protrudes outward. For example, when a vehicle traveling on the road accidentally gets on the R portion. Even so, it is possible to disperse the impact at the time of the ride along the shape of the R portion, and the base portion and the light emitter are not easily damaged.

  In addition, since the light emitting window portion along the shape of the R portion is formed from the front side to the side of the light emitter, the light emitting window portion covers a wide range of light emitted from the light emitter from the front side to the side. Permeate from outside to outside. Therefore, the said light can be visually recognized over a wide range, and the light from a light-emitting body can be reliably visually recognized not only to a vehicle but to a pedestrian.

  In particular, it is preferable that the light emitting window part is formed by perforating the R part, and a pair is formed via the top part of the R part.

  In general, a road marking body, for example, where the impact when the vehicle is mounted as described above is often concentrated on the top of the R portion, is drilled (perforated). ) And the strength of the one end portion may be reduced, and may be easily broken. Therefore, a pair of light emitting window portions formed by being drilled in the R portion are formed via the top portion of the R portion, that is, the light emitting window portion is formed avoiding the top portion of the R portion and drilled in the top portion. The strength of the top portion can be improved by adopting a configuration that does not provide (in other words, the top portion of the R portion is not perforated). Accordingly, the entire road marking body can be made more robust.

  In addition, a light entrance window portion for allowing external light to enter is formed on the base portion, and a reflector for reflecting the external light incident on the light entrance window portion to the outside is provided on the base portion. It is preferably placed in the light window, and the road marking object can be recognized by the reflected light from the reflector. Therefore, even when the light emitting body stops emitting light due to a failure, etc., the road marking The display function of the body can be obtained.

  According to the road surface mounting structure of the road marking body according to the present invention, the outer surface of the cylindrical portion is configured to be elastically expanded so that the outer surface of the cylindrical portion presses the inner surface of the small-diameter hole. Even if a strong frictional force is generated between the inner surface of the hole and the pole portion and the base portion are provided separately, the risk of the base portion rotating can be reduced.

  According to the road surface mounting method of the road marking body according to the present invention, the bolt portion provided on the pole portion is screwed to the anchor nut portion embedded in the road surface, so that the pole portion and the base portion are simultaneously connected to the road surface. However, by tightening the bolt part to the anchor nut part and pressing the outer surface of the cylindrical part against the inner surface of the small-diameter hole, strong friction is generated between the outer surface of the cylindrical part and the inner surface of the small-diameter hole. Even if the pole portion and the base portion are separated from each other by generating a force, it can be attached to the road surface so as to reduce the risk of the base portion rotating.

  BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a front view showing a first embodiment of a road marking structure for a road marking body, a road surface mounting method for a road marking body, and a road marking body having the road surface mounting structure according to the present invention. The pole portion 1 is provided with a cylindrical pedestal portion 14 attached to the lower end of the cylindrical main body portion 11, and a cylindrical portion 12 protruding downward from the lower surface of the pedestal portion 14. A bolt portion 13 is formed so as to protrude further downward from the lower end. The main body part 11 is formed of a synthetic resin material rich in elasticity such as a polyurethane-based synthetic resin so that it bends and restores when a strong external force such as a vehicle collision is applied. The outer diameter of the pedestal part 14 is the main body part. 11 is provided between the upper surface 141 of the pedestal part 14 and the outer surface of the main body part 11, that is, in the middle of the pole part 1 in the vertical direction, a step part 15 whose upper part is reduced in diameter is provided. ing.

  An anchor nut portion 3 is embedded in the road surface G. The anchor nut portion 3 is threaded into the inner surface in advance with a screw thread on which the bolt portion 13 can be screwed. The base portion 2 is provided with a large-diameter hole 21 that opens upward and has a bottom portion 23, and a small-diameter hole 22 that penetrates through the center of the bottom portion 23. In order to attach the road marking body 10 to the road surface G, first, the cylindrical portion 12 and the bolt portion 13 of the pole portion 1 are inserted into the large-diameter hole 21 and the small-diameter hole 22 from above the base portion 2, and the bolt portion 13 is screwed to the anchor nut portion 3. The bottom portion 23 of the base portion 2 is sandwiched between the pedestal portion 14 provided at the lower end of the pole portion 1 and the road surface G by screwing and tightening the bolt portion 13 to the anchor nut portion 3. Further, the outer diameter of the pedestal portion 14 is smaller than the inner diameter of the large-diameter hole 21 and larger than the inner diameter of the small-diameter hole 22, so that the bottom 23 can be easily clamped only by screwing the bolt portion 13. be able to.

  A retroreflector R1 that is a reflective sheet is provided above the pole part 1, and a retroreflector R2 that is a glass bead-embedded reflector is attached to the outer surface of the pedestal part 14 to enhance visibility at night. However, since the pedestal portion 14 is hidden by the base portion 2 as will be described later, the retroreflector R2 may not be provided in advance.

  FIG. 2 is a longitudinal sectional view of the vicinity of the bolt portion 13 when the bolt portion 13 is screwed to the anchor nut portion 3. First, in FIG. 2A, the pedestal portion 14 forming the pole portion 1 is formed of a polyurethane-based synthetic resin that is the same material as the main body portion 11, and the cylindrical portion 12 and the bolt portion 13 are connected at the time of molding. The included anchor bolt A and the cylindrical reinforcing portion 16 that prevents excessive bending of the main body portion 11 are integrally formed at a time. In a state where the bolt portion 13 is not tightened so much in the anchor nut portion 3, no external force is applied to the tubular portion 12, and the outer diameter of the tubular portion 12 is made smaller than the inner diameter of the small-diameter hole 22. Thus, the cylindrical portion 12 can be smoothly inserted into the small-diameter hole 22. Further, the anchor nut portion 3 is fixed and embedded in the road surface G using an adhesive or the like, but the upper surface 31 of the anchor nut portion 3 is made lower than the road surface G, and between the upper surface 31 and the road surface G height. The cylindrical portion 12 can be loosely fitted, and a space portion 32 having an inner surface larger than the inner diameter of the small-diameter hole 22 is provided.

  Next, in FIG. 2B, when the bolt portion 13 is further tightened, the cylindrical portion 12 comes into contact with the upper surface 31 of the anchor nut portion 3, and when further tightened, it is a polyurethane-based synthetic resin that is an elastic material. The tubular portion 12 elastically expands outward in the space portion 32. Then, the outer surface 121 of the cylindrical portion 12 that is elastically expanded hits the inner surface 221 of the small-diameter hole 22 and presses the inner surface 221 because the inner surface of the space portion 32 is larger than the inner diameter of the small-diameter hole 22.

  By pressing the cylindrical portion 12 against the inner surface 221 of the small-diameter hole 22, the base portion 2 can be made much more difficult to rotate than when the road surface G and the pedestal portion 14 are clamped. A light emitting member 4 provided with a light emitting body 41 which is a bullet-type light emitting diode is attached to the base portion 2, and light L from the light emitting body 41 is emitted directly from the light emitting body 41 to the outside of the base portion 2. It is made like that. By using a bullet-type light-emitting diode as the light-emitting body 41, the light L can be viewed in the distance with a small amount of energy, but the angle at which the light L is visually recognized is limited due to the limited viewing angle. When the part 2 rotates and the optical axis of the light L shifts, the initial visibility may be significantly impaired. By applying the road surface mounting structure according to the present invention to the base portion 2, it is possible to prevent the base portion 2 from rotating and greatly increase the effect of the application. The angle formed by the road surface G and the optical axis of the light L may be appropriate, but if it is set to about 1 to 2 °, it is aligned with the line of sight of the driver of a passenger car 50 to 100 m away and visibility is improved. For fixing the base portion 2, an adhesive means such as an adhesive may be used in combination with the lower surface 2 a of the base portion 2, but in order to make the light emitting member 4 detachable from the base portion 2, the bolt portion 13. It is preferable to use only fixing by screwing.

  Here, the light emitting member 4 attached in order to provide the light emitting body 41 to the base portion 2 is a detailed synthetic resin molded body having a symbol opened in detail in FIG. In addition to the light emitter 41, the solar cell 44 and the electronic substrate 45 are housed and integrated in a space formed by the main body 42 and the bottom plate 43 that closes the lower surface of the main body 42, and is formed as a separate member from the base portion 2. It has been done. The light emitting member 4 has an outer shape that can be fitted to the inner surface of a concave portion 24 formed by denting the base portion 2 from below, and the base portion 2 is fitted in the concave portion 24 from below. When fixed to the road surface G, the light emitting member 4 is sandwiched between the base portion 2 and the road surface G. The concave portion 24 is provided with a light emitting window portion 25 that transmits light L emitted from the light emitter 41 and a light incident window portion 26 that allows the sunlight to enter the solar cell 44. The light emission window portion 25 and the light entrance window portion 26 may be translucent, may have a through-hole shape as in the first embodiment, or may be provided with a highly transparent plate-like body. .

  In the light emitting window portion 25 and the light entrance window portion 26 described above, the upper surface 424 of the main body 42 of the light emitting member 4 is located on the inner side of the upper surface 2b of the base portion 2. The tire first hits the base portion 2 so that it does not directly hit the light emitting member 4, so that the impact on the light emitting member 4 when the vehicle gets on is reduced and the risk of damage to the light emitting member 4 is reduced. It is made like that.

  FIG. 3 shows an example of a road marking body 10 applied to the road surface mounting structure according to the present invention shown in FIG. 2, (a) is a front view in a state where it is installed on the road surface G, (b) is A top view and (c) are bottom views. First, in FIG. 3A, the road marking body 10 is formed with a base portion 2 so as to protrude from the lower end of the pole portion 1 to both sides, and the base portion 2 includes a light emitter 41. The light-emitting member 4 is provided, and the light-emitting body 41 is lit or blinked to alert the presence of the road marking body 10 at night. The side surface of the base portion 2 is an inclined surface whose diameter is increased downward, so that impact is reduced when the vehicle is on board.

  Next, in FIG. 3 (b), the base portion 2 is formed in an oval shape by projecting in a horseshoe shape in two directions on a straight line from the pole portion 1, and a solar cell 44 is disposed on the upper surface 2 b of the base portion 2. Has been. Here, the width W of the base portion 2 is set to 150 mm, which is equal to or smaller than the road marking line, so that when the road marking body 10 is installed on the road marking line, the base portion 2 The advantage of applying the small diameter pedestal pole cone without overhanging is less likely to be impaired. The length L of the base portion 2 is along the extending direction of the road marking line, and can be set to an appropriate length. It is preferable because excessive stress can be prevented from being applied to the narrow portion.

  3C, the light emitting member 4 is fitted and attached from the lower surface 2a of the base portion 2, and the fitted light emitting member 4 is fastened to the base portion 2 with screws 47 on the base plate 2. As shown in FIG. It is attached by being. Since the screws 47 are fastened to the lower surface 2a of the base portion 2, there is no risk of damaging the tires when the vehicle is launched, and when the light emitting member 4 is damaged, the pole portion 1 and the base portion are removed from the road surface G. The light emitting function can be easily maintained by removing 2 and removing the screw 47 to remove the damaged light emitting member 4 from the base portion 2 and replacing it with a new light emitting member 4.

  Moreover, the base part 2 can also be used as a self-light-emitting road fence by the base part 2 alone. In that case, the small-diameter hole 22 through which the bolt part 13 near the center of the base part 2 is inserted may be used for attachment to the road surface G as in the case of using it as a road marking pillar, but in the first embodiment, Four countersink portions 27 are provided in the vicinity of the side surface of the base portion 2, and fixing holes 28 penetrating in the vertical direction are provided on the bottom surfaces of the countersink portions 27, and mounting bolts are provided in the fixing holes 28. And can be screwed onto an anchor nut embedded in the road surface G in advance. By fixing to the road surface G with mounting bolts in the vicinity of the side surface of the base portion 2, even if the base portion 2 is not fixed using a wide area of the bottom portion 23, the base portion 2 is turned around. The rise is prevented, and the base portion 2 can be reliably fixed over a long period of time. When used as such a self-luminous roadway, it is preferable to close the large-diameter hole 21 with a cap or the like.

  FIG. 4 is a perspective view showing an example of a mounting jig used in the road surface mounting method for a road marking body according to the present invention. The mounting jig 5 has a plate shape in which a through hole 52 into which the pole portion 1 of the road marking body 10 can be inserted and a fitting portion 53 protruding downward at three locations around the through hole 52 are provided. Similarly, a plate-like handle portion 54 is provided on the main body 51, which is a ring body, and is integrally formed of a metal material.

  FIG. 5 is a cross-sectional view showing an example of a road surface mounting method for a road marking body according to the present invention using the mounting jig 5 shown in FIG. The pole portion 1 has a planar stepped portion 15 with the outer portion of the pedestal portion 14 facing upward, and jig holes 17 are formed at substantially equal intervals on the upper surface of the stepped portion 15 (upper surface 141 of the pedestal portion). It is open. The main body portion 11 is inserted into the through hole 52 of the mounting jig 5 so that the main body 51 is positioned above the pedestal portion 14, and the fitting portion 53 provided on the lower surface of the main body 51 is fitted into the jig hole 17. Is done. Here, the position and number of the fitting portion 53 and the jig hole 17 are the same, and the fitting portion 53 can be fitted into all the jig holes 17. With the fitting portions 53 fitted in all the jig holes 17, the handle portion 54 of the mounting jig 5 is rotated to rotate the pole portion 1, and the bolt portion 13 is screwed to the anchor nut portion 3. If this is done, the tightening force by the grip portion 54 is much stronger than when the pole portion 1 is gripped and rotated, and the elastic expansion of the cylindrical portion 12 can be reliably performed. Even when the upper surface 141 of the pedestal portion 14 is lower than the upper surface 2b of the base portion 2 in the state of being attached to the base portion 2, the relatively strong pedestal portion 14 is used without using the main body portion of the soft pole portion 1. And tightening can be performed quickly and powerfully.

  Next, a second embodiment of the road marking body according to the present invention will be described. In addition, the road surface mounting structure and road surface mounting method of the road marking body according to the second embodiment are the same structure and method as the road surface mounting structure and road surface mounting method of the road marking body according to the first embodiment.

  FIG. 6 shows a road marking body 10 in the second embodiment. The road marking body 10 is configured such that a base portion 2 is provided so as to protrude from the lower end of the pole portion 1 to both sides, and a light emitting member 4 having a light emitting body 41 is provided on the base portion 2 in the longitudinal direction. At least one end portion 29 in the direction is detachably provided. In addition, the case where the light-emitting body 41 is each provided in the both ends of a longitudinal direction may be sufficient.

  The road marking body 10 is configured by separating the pole portion 1 and the base portion 2 and is fixed to the road surface G using a bolt portion 13 provided on the pole portion 1. On a line such as a center line provided between lanes, it is fixed and arranged along the longitudinal direction of the base portion 2 in the extending direction of the line, and the light-emitting body 41 is lit or blinks to indicate roads at night By awakening the presence of the body 10, it is used as a lane center line display, a lane guidance sign, a traffic regulation guidance sign, or a warning object such as entry prohibition.

  The pole portion 1 has a cylindrical pedestal portion 14 attached to the lower end of the cylindrical main body portion 11, and a cylindrical portion 12 is provided to protrude downward from the lower surface of the pedestal portion 14. A bolt portion 13 is formed projecting downward from the lower end of the cylindrical portion 12.

  The main body 11 is configured to bend when a strong external force such as a vehicle collision is applied, and is configured to be restored when the external force is removed. It is formed from a synthetic resin material rich in. In addition, since the pole portion 1 has an outer diameter of the pedestal portion 14 larger than the outer diameter of the main body portion 11, it is between the upper surface 141 of the pedestal portion 14 and the outer surface of the main body portion 11, that is, the upper and lower sides of the pole portion 1 A stepped portion 15 whose upper diameter is reduced is formed in the middle of the direction.

  Further, a retroreflector R1 that is a reflection sheet is provided above the pole part 1, and a retroreflector R2 that is a glass bead embedded reflector is attached to the outer surface of the pedestal part 14 to improve visibility at night. I try to increase it. As will be described later, since the pedestal portion 14 is hidden by the base portion 2, the retroreflector R2 may not be provided in advance.

  An anchor nut portion 3 is embedded in the road surface G. The anchor nut portion 3 is pre-threaded on the inner surface with a thread that can be screwed onto the bolt portion 13.

  As shown in FIGS. 7 to 9, the base portion 2 is formed in an elliptical shape by projecting both end portions 29 and 29 in a horseshoe shape in two directions on a straight line from the pole portion 1. Specifically, the base portion 2 is formed as an R portion 29 curved in an arc shape in which at least one end portion 29 in the longitudinal direction, in the second embodiment, both end portions 29 and 29 are convex outward. The both ends of the width direction are formed in parallel straight lines. In addition, the circular arc shape of the longitudinal direction both ends 29 and 29 is a shape which touches the linear shape of the width direction both ends.

  The dimension W in the width direction of the base part 2 is 150 mm, which is the same as a road marking line such as a center line, or less. Thus, for example, when the road marking body 10 is installed on a road marking line such as a center line, the base portion 2 does not protrude from the line, and therefore, an advantage in the case of applying a small diameter pedestal pole cone. Is less likely to be damaged.

  In addition, the longitudinal direction of the base part 2 is a direction along the extending direction of the road marking line in the installation state on the road surface G, and the dimension L can be an appropriate length. It is preferable that the width W is approximately twice or less than the dimension W in the width direction, and excessive stress on the narrowed portion at the connecting portion with the pole portion 1 can be prevented.

  The base portion 2 is configured so that its thickness gradually decreases from the elliptical center portion (center in the longitudinal direction and width direction) outward. That is, the thickness of the base portion 2 is thicker at the center, and is thinner toward the end in the longitudinal direction or closer to the end in the width direction than the center. Specifically, the lower surface 2a of the base portion 2 is a flat surface, while the upper surface 2b is an inclined surface inclined downward from the central portion in the longitudinal direction and the width direction.

  Further, the side surfaces 2c and 2d of the base portion 2 extending from the outer peripheral edge of the upper surface are inclined surfaces whose diameter is increased downward. Specifically, both the width-direction side surfaces 2c and the longitudinal-direction side surfaces 2d of the base portion 2 are inclined surfaces that are inclined downward toward the outside. In addition, the inclination angle of the width direction both side surfaces 2c and the longitudinal direction both side surfaces 2d is larger than the inclination angle of the upper surface 2b. As described above, by making the side surfaces 2c and 2d of the base portion 2 into inclined surfaces, the impact at the time of getting on the vehicle is reduced.

  On the upper part of the base part 2, a light entrance window part 26 is formed to allow light from the outside (external light) to enter. Specifically, the light entrance window portion 26 is an opening formed by drilling in the upper portion of the base portion 2, and is formed along the inclination of the upper surface 2 b of the base portion 2. Therefore, the opening direction of the light entrance window 26 is obliquely upward slightly inclined toward one end side in the longitudinal direction. In the second embodiment, the light entrance window portion 26 is provided only on one end portion 29 side of the longitudinal end portions of the upper surface 2b.

  At least one end portion 29 in the longitudinal direction of the base portion 2 (in the second embodiment, only one end portion) transmits light L emitted from the light emitter 41 provided in the base portion 2 to the outside. For this purpose, a light emission window 25 is formed. The light emission window portion 25 is formed along the R shape of the one end portion 29. That is, the light emission window part 25 is formed in the circular arc shape which protrudes outward.

  The light emission window portion 25 is formed by drilling in the R portion 29. That is, the light emission window portion 25 is an opening formed along the shape of the R portion 29, and is formed on the side surface 2 d in the longitudinal direction of the base portion 2 in the second embodiment. Accordingly, the opening direction of the light emitting window portion 25 is obliquely upward inclined toward the one end portion 29 side in the longitudinal direction, and is a direction inclined further in the longitudinal direction than the opening direction of the light incident window portion 26. ing.

  A pair of light emitting window portions 25 is formed via the top portion 291 of the R portion 29. Specifically, the light emission window 25 includes a region from one end of the R portion 29 to the front of the top 291 and a region from the other end of the R portion 29 to the front of the top 291. Each pair is formed by hollowing out, and therefore the light emission window portion 25 is not formed at the top portion 291 of the R portion 29.

  The light emitting window portion 25 and the light entrance window portion 26 may be translucent, may have a through-hole shape as in the second embodiment, and are provided with a highly transparent plate-like body. Also good.

  On the lower surface 2 a side of the base portion 2, a concave portion 24 for accommodating the light emitting member 4 including the light emitting body 41 is formed. Specifically, the recessed portion 24 is formed in the entire area of the lower surface 2a side of at least one end portion 29 (only one end portion in the second embodiment) of the base portion 2, and the light emitting window portion 25. And the light entrance window portion 26. In the concave portion 24, engagement concave portions 30 are formed on both sides in the width direction of the light incident window portion 26.
