  FIG. 5 is a side view showing the wiring cover 10 in a state where the cover piece 38 is folded. As shown in FIG. 5, the through hole 36 is formed by opening the cover piece 38 from the housing portion 16. The cover piece 38 can be folded, for example, by gripping it with a tool such as pliers and pulling it away from the housing portion 16. In the present embodiment, the casing portion 16 is provided with four through holes 36 at positions shifted by 90 °, and one or a plurality of cover pieces located in a direction in which the electric wire 7 (see FIG. 1) is desired to be led out. What is necessary is just to break and use 38. The number and direction of the through holes 36 can be changed as appropriate according to the specifications such as the installation location of the wiring cover 10.

  6 (a) is a partially enlarged bottom view of the housing portion 16 showing the cover piece 38 before being broken, and FIG. 6 (b) is attached so that the broken cover piece 38 closes the through hole 36. FIG. It is the elements on larger scale of the housing | casing part 16 which shows the state performed. As shown in FIG. 6A, the cover piece 38 is provided at a position near the outer surface of the side wall 34 in the through hole 36 before being folded. A pair of locking portions 40 is provided in the through hole 36 at the back side of the cover piece 38, that is, at a position away from the outer surface of the side wall 34. The pair of locking portions 40 are integrally formed on the inner surface of the side wall 34. The dimension between the pair of locking portions 40 is formed such that the cover piece 38 that has been broken off can be detachably held. As a result, as shown in FIG. 6B, when the broken cover piece 38 is inserted between the pair of locking portions 40 from below the housing portion 16, the cover piece 38 blocks the through hole 36. Can be held in a state. Further, the cover piece 38 can be removed from the housing portion 16 so as to open the through hole 36 again.

  Since the cover piece 38 thus separated can be detachably held in a state in which the through hole 36 of the housing portion 16 is closed, the wiring cover 10 is moved to another place and another through hole is provided. When the electric wire 7 is led out from 36, the unused through hole 36 can be closed. Accordingly, it is possible to prevent dust and dirt from entering the inside of the wiring cover 10 by using the wiring hole 36 while being open.

  Referring to FIGS. 2 and 4 again, two through holes 42 are formed in the top surface 32 of the housing portion 16. The two through holes 42 are arranged side by side in one diagonal direction of the top surface 32. When the screws 44 are inserted into the through holes 42 and tightened into the screw holes 26 of the base member 14, the housing portion 16 is fixed to the base member 14. As a result, the housing portion 16 is fixed to the floor plate 4.

  As shown in FIG. 4A, the top surface 32 of the housing portion 16 has two storage portions 45 that are recessed. The two storage portions 45 are arranged side by side in another diagonal direction different from the direction in which the two through holes 42 are arranged. These storage portions 45 function as storage portions for storing the cover pieces 38 separated from the housing portion 16. In FIG. 4A, a state where the cover piece 38 is stored in one storage portion 45 is indicated by a one-dot chain line. If the cover piece 38 is stored in the storage portion 45 in this way, the upper portion of the housing portion 16 is covered with the top plate 18, so that the cover piece 38 is not lost. Therefore, even when it is necessary to close the opened through hole 36 by moving the wiring cover 10 as described above, the stored cover piece 38 can be easily taken out from the storage portion 45 and the pair of locking portions can be easily removed. It can be mounted between 40.

  As shown in FIGS. 4A and 4B, the top surface 32 of the housing portion 16 is formed with a rib 46 having a substantially cross shape when viewed from above. The rib 46 has a function of reinforcing the strength of the top surface 32. Further, as shown in FIG. 4B, the upper end edge of the rib 46 is formed to be inclined upward toward the center of the top surface 32. Thereby, as will be described later, the top plate 18 attached to cover the top surface 32 of the housing portion 16 can be supported from the inside, and the function of reinforcing the top plate 18 is also achieved.

  Further, as shown in FIGS. 2 and 4A, four locking holes 48 are formed in the top surface 32 of the housing portion 16. The four locking holes 48 are formed at positions corresponding to the locking protrusions 50 protruding from the top plate 18.

  FIG. 7 is a perspective view of the top plate 18 of the wiring cover 10. The top plate 18 is preferably formed of a resin material such as ABS resin. The top plate 18 is formed in the same size and shape as the top surface 32 of the housing portion 16 in plan view. Four locking protrusions 50 are provided on the rear surface of the top plate 18. The locking hole 48 has a flange at the tip. As a result, when the top plate 18 is pushed over the top surface 32 of the housing 16, the locking projection 50 is inserted into the locking hole 48 of the top surface 32 and locked. As a result, the top plate 18 is detachably attached to the housing unit 16. When removing the top plate 18, for example, if a tool such as a screwdriver is inserted between the top plate 18 and the housing portion 16 and squeezed, the locking projection 50 is elastically deformed and comes out of the locking hole 48. Thereby, the top plate 18 can be removed from the housing portion 16.

  FIG. 8A is a longitudinal sectional view showing a state in which the wiring cover 10 is fixed to the base member 14, and FIG. 8B is an enlarged view of a portion A in FIG.

  As shown in FIG. 8A, when the top plate 18 is attached to the housing portion 16, as described above, the upper edge of the rib 46 formed on the top surface 32 of the housing portion 16 is the top plate. 18 is located in contact with or close to a rib 19 projecting from the back surface of 18. Thereby, even when a load or impact is applied to the wiring cover 10 that protrudes from the floor surface 1 from above (for example, when it is stepped on by a person), the top plate 18 can be prevented from being damaged.

  Further, as shown in FIGS. 8A and 8B, a boss portion 17 extending downward from the top surface 32 is integrally formed in the housing portion 16, and a screw is provided in the boss portion 17. A through hole 42 for inserting 44 is formed. The screw 44 is inserted into the through hole 42 from the top surface 32 of the housing portion 16, and the lower end portion is screwed into the screw hole 26 (see FIG. 3A) of the base member 14 and tightened.

  When the housing portion 16 is fixed in this manner, as shown in FIG. 8B, between the lower end of the boss portion 17 of the housing portion 16 and the convex portion 28 at the upper end of the screw hole of the base member 14. A gap 52 is formed. The dimension g of the gap 52 is such that the base member 14 is moved at a predetermined angle (for example, from the state in which the mounting portion 22 of the base member 14 is screwed to the floor plate 4 fixed to the wiring box 3 until it does not rotate). , 90 °), when the screwing is loosened, it is preferable that the distance is set to be equal to or less than the distance (for example, 0.5 mm) that the base member 14 rises from the floor plate 4.

  By forming such a gap 52, when the screw 44 is tightened, the lower end of the side wall 34 of the housing portion 16 is in contact with the surface of the floor plate 4. A force that is lifted upward acts on. As a result, the frictional force between the male screw portion of the mounting portion 22 of the base member 14 and the female screw portion of the floor plate 4 is increased, and the base member 14 is difficult to rotate with respect to the floor plate 4. As a result, the wiring cover 10 including the housing 16 fixed to the base member 14 is attached so as not to rotate with respect to the floor plate 4. Further, since the dimension g of the gap 52 is set to be equal to or less than the distance that rises when the base member 14 is rotated by a predetermined angle, the angular position of the base member 14 can be adjusted within the range of the predetermined angle. That is, after adjusting the angular position of the housing | casing part 16 attached to the base member 14, and the wiring cover 10 containing this, it can fix to the floor plate 4. FIG.

  FIG. 9 is a bottom view of the wiring cover 10 of FIG. As shown in FIG. 9, the outer peripheral edge of the flange portion 20 of the base member 14 is located in the side wall 34 of the housing portion 16, and is close to or in contact with the inner side surface of the side wall 34. In the present embodiment, the outer peripheral edge of the flange portion 20 is in contact with or close to the side wall 34 of the housing portion 16 at eight locations indicated by alternate long and short dash lines in FIG. Thereby, it is possible to support the housing | casing part 16 of the wiring cover 10 from an inner side. Therefore, when a load or an impact is applied to the wiring cover 10 from the lateral direction (for example, when a person trips or a wheel of a carriage collides), it is possible to prevent the casing 16 made of a resin member from being damaged.

  As described above, the present embodiment is the wiring cover 10 that has the housing portion 16 attached on the floor surface 1 and leads out the electric wire 7 wired through the opening of the floor surface 1. The housing portion 16 of the wiring cover 10 includes a through hole 36 for leading out the electric wire 7 and a cover piece 38 provided in the housing portion 16 in a state where the through hole 36 is closed. The cover piece 38 is integrally connected to the housing portion 16 by a connecting portion 37 at the inner peripheral portion of the through hole 36. The through-hole 36 is provided with a locking portion 40 that detachably holds the cover piece 38 separated from the housing portion 16. According to this configuration, by breaking the cover piece 38 and opening the through hole 36, the electric wire 7 can be easily led out and the through hole 36 can be closed again by the broken cover piece 38. it can.

  Further, the wiring cover 10 further includes a top plate 18 that is detachably attached to the housing portion 16, and houses the separated cover piece 38 on the top surface 32 of the housing portion 16 that is covered by the top plate 18. A storage unit 45 is provided. According to this configuration, the cover piece 38 separated in the storage portion 45 is stored so that it is not lost. Therefore, even when it is necessary to close the through hole 36 once opened due to the transfer of the wiring cover 10, the stored cover piece 38 can be taken out from the storage portion 45 and easily attached.
