The tip edge of the protrusion 17c has a semicircular arc shape. A substantially arc-shaped protrusion 17d that curves rearward in a direction away from the lid body 15 is protrudingly provided at a midway point in the width direction of the inner surface in the vehicle width direction of the curved portion 17b of the main wall portion 17a. ing. A gear 17k is formed on the surface of the protruding portion 17d on the vehicle rear side. A substantially circular bearing hole 17e is formed through the tip of the protrusion 17c, and an arm-side boss portion 17f that protrudes outward in the vehicle width direction is formed on the outer peripheral edge of the bearing hole 17e. A recess 17g that is recessed outward in the vehicle width direction and opens rearward is formed at the rear end of the protrusion 17c on the proximal side of the bearing hole 17e, and a lid side locking portion is formed on the bottom surface of the recess 17g. A lid-side locking hole 17h is formed through the lid. An outer circumferential rib 17i that protrudes outward in the vehicle width direction is formed on the outer circumferential edge of the main wall portion 17a over the entire circumference. On the main wall 17a inside the outer peripheral rib 17i, an inner rib 17j that protrudes outward in the vehicle width direction is formed in a substantially honeycomb shape and is continuous with the arm-side boss portion 17f and the outer peripheral rib 17i. Furthermore, an engaged portion (not shown) that engages with the engaging portion (not shown) of the box member 5 is provided on the vehicle front side of the lid 11.

Then, with the hinge portion 5i of the box member 5 disposed inside the arm portion 17 of the lid 11 in the vehicle width direction, the through hole 5j of the hinge portion 5i of the box member 5 and the arm portion 17 of the lid 11 are connected to each other. The hinge shaft 13 is inserted through the bearing hole 17e. Further, a braking gear of a rotary damper (not shown) attached to the box member 5 is engaged with a gear 17k of the arm portion 17 of the lid 11. The hinge shaft 13 is equipped with a torsion coil spring 19 also shown in FIG. The torsion coil spring 19 has a pair of winding parts 19a that are externally mounted on the hinge shaft 13, and extends from the inner end (one end) of both the winding parts 19a in the vehicle width direction. A connecting portion 19b serving as a first extending portion that connects to each other; and an outer extending portion 19c serving as a second extending portion extending to the outer end (the other end) in the vehicle width direction of both winding portions 19a. have. The connecting portion 19b includes a pair of straight portions 19d extending straight from the inner ends of both winding portions 19a in the vehicle width direction in a common direction (tangential direction of the hinge shaft 13), and a pair of straight portions 19d extending in a semicircular arc shape. It consists of a connecting part 19e which is curved and connects both straight parts 19d.

The connecting portion 19b of the torsion coil spring 19 is inserted from above into the insertion hole 7g of the bracket in a downwardly protruding state. Further, the vicinity of the tips of both outwardly extending portions 19c of the torsion coil spring 19 are locked in the lid-side locking holes 17h of the lid 11. Specifically, the circumferential movement of the torsion coil spring 19 is regulated by passing through the lid-side locking hole 17h of the lid 11 near the tips of the both outwardly extending portions 19c. Further, the proximal end portion of both outer extending portions 19c is inserted through the guide hole 5m of the box member 5 than the lid side locking hole 17h insertion portion. In this state, the torsion coil spring 19 biases the lid 11 in the lid opening direction.

Furthermore, plate-shaped side covers 21 are attached to both left and right sides of the box body 5', with the plate surfaces oriented in the vehicle width direction. A tapping screw fastening hole (not shown) is formed through the rear end of the side cover 21, and the tapping screw fastening hole (not shown) corresponds to the second tapping hole 5s of the box member 5. The second tapping screw 23 is inserted into the tapping screw fastening hole and the second tapping hole 5s and fastened.

In the console box 1 configured as described above, when the lid is closed, the engaging portion (not shown) of the box member 5 engages with the engaged portion (not shown) of the lid 11, so that the lid is closed. The opening operation of 11 is regulated. Then, when the engagement part (not shown) of the box member 5 and the engaged part (not shown) of the lid 11 are released from this state, the lid 11 is moved by the biasing force of the torsion coil spring 19. It rotates upward around the hinge shaft 13 to reach the open position, and is maintained in the open state by the biasing force of the torsion coil spring 19. At this time, in the process of the lid 11 rotating from the closed position to the open position, the rotational speed of the lid 11 is suppressed by the damping force of a rotary damper (not shown) attached to the box member 5. At this time, the outer extending portion 19c of the torsion coil spring 19 rotates within the guide hole 5m in conjunction with the lid 11. Further, by pressing the lid 11 downward from the lid open state, the lid 11 can be rotated to the closed position against the biasing force of the torsion coil spring 19. Also at this time, the outwardly extending portion 19c of the torsion coil spring 19 rotates within the guide hole 5m in conjunction with the lid 11.

In order to assemble the console box 1 configured as described above, first, both hinge parts 5i of the box member 5 are placed inside both arm parts 17 of the lid 11, and both hinge parts 5i of the box member 5 are assembled. The through hole 5j of the portion 5i and the bearing hole 17e of both arm portions 17 of the lid 11 are made to face each other, and both outer extension portions 19c of the torsion coil spring 19 are inserted into the guide hole 5m of the box member 5. It is inserted (locked) into the lid side locking hole 17h of the lid 11. The hinge shaft 13 is connected to the bearing hole 17e of one arm portion 17 of the lid 11, the through hole 5j of one hinge portion 5i of the box member 5, both winding portions 19a of the torsion coil spring 19, and the other side of the box member 5. through the through hole 5j of the hinge portion 5i and the bearing hole 17e of the other arm portion 17 of the lid 11 in this order. As a result, both winding portions 19a of the torsion coil spring 19 are mounted on the hinge shaft 13, and the rear end edge of the lid 11 can be rotated by the hinge shaft 13 at the rear end edge of the opening 5o of the box member 5. connected to. Further, the lid 11 is closed. In this state, as shown in FIG. 7, no external force is applied to the torsion coil spring 19, and the connecting portion 19b of the torsion coil spring 19 protrudes toward the rear of the vehicle. Then, by approaching the connecting portion 19b of the torsion coil spring 19 from the rear of the vehicle with the upper protruding plate portion 7f of the bracket 7 with its plate surface facing in the longitudinal direction of the vehicle, the insertion hole 7g of the bracket 7 is Insert the connecting portion 19b of the torsion coil spring 19 into the. In this state, the end portion of the bracket 7 on the side opposite to the insertion hole 7g is spaced apart from the rear wall portion 5a of the box member 5 to the rear of the above-mentioned fixed position. From this state, the end of the bracket 7 on the side opposite to the insertion hole 7g is rotated forward (in the direction indicated by the arrow X in FIG. 7) using the vicinity of the insertion hole 7g of the bracket 7 as a fulcrum, and By approaching the wall portion 5a, the connecting portion 19b of the torsion coil spring 19 is pressed from above by the outer peripheral edge of the insertion hole 7g of the bracket 7 and rotated downward. As a result, the torsion coil spring 19 deforms against its elastic force. At this time, the force applied to the end of the bracket 7 on the side opposite to the insertion hole 7g acts on the connecting portion 19b of the torsion coil spring 19 using the vicinity of the insertion hole 7g of the bracket 7 as a fulcrum, so a relatively small force is applied due to the lever principle. The torsion coil spring 19 can be deformed. In addition, the locking piece 7i of the bracket 7 slides into contact with the guide surface 5h of the box member 5 in the process of rotating the bracket 7 and is bent, and when it reaches the insertion hole 5c as shown in FIGS. 4 and 8, it returns to its original state. It returns to its shape and comes into contact with the edge of the insertion hole 5c from the front to restrict rearward movement of the end of the bracket 7 on the side opposite to the insertion hole 7g. Next, the bracket 7 is fixed to the rear wall portion 5a of the box member 5 by inserting and fastening the first tapping screw 9 into the tapping screw insertion hole 7e of the bracket 7 and the first tapping hole 5g of the box member 5. do. In this way, the step of deforming the torsion coil spring 19 against its elastic force is the insertion step of inserting the connecting portion 19b of the torsion coil spring 19 into the insertion hole 7g of the bracket 7, and the outer side of the torsion coil spring 19. Since the extension part 19c is provided separately from the locking process of locking the lid side locking hole 17h of the lid 11, even when the biasing force of the torsion coil spring is increased, the torsion coil is not removed during the insertion process and the locking process. It is not necessary to greatly deform the spring 19 against its elastic force. Therefore, the work of assembling the torsion coil spring 19 becomes easier. Finally, the tapping screw fastening hole (not shown) of the side cover 21 is made to correspond to the second tapping hole 5s of the box member 5, and the second tapping screw 23 is inserted into the tapping screw fastening hole and the second tapping hole 5s. By tightening the box body 5', the side covers 21 are attached to both the left and right sides of the box body 5'.

Therefore, according to this embodiment, since the bracket 7 is made of metal, the peripheral edge of the insertion hole 7g of the bracket 7 is less likely to be damaged by the elastic force of the torsion coil spring 19, compared to a case where the bracket 7 is made of resin.

In this embodiment, the bracket 7 is provided with two vertical plate portions 7b and two locking piece portions 7i, but may be provided with one each. Furthermore, although the bracket 7 is shaped like a bent metal plate, it may also be shaped like a rod.

In addition, in this embodiment, the bracket 7 is fastened only to the rear wall 5a of the box main body 5, but among the right side wall (not shown), left side wall 5a', and bottom wall (not shown), It is also possible to further fasten at least one of the following. Thereby, the rigidity of the box body 5 can be improved.

Further, in this embodiment, the rear end edge of the lid 11 is connected to the rear end edge of the opening 5o of the box member 5, but the other end edge of the lid 11 is connected to the other end edge of the opening 5o of the box member 5. You may.
