An insertion hole (9), which is provided with a peripheral surface bottom portion (5a) facing the bottom surface portion (10a), and is inserted into the peripheral surface bottom portion, and an insertion piece (12). On the other hand, it is provided with a projecting fulcrum part (14) formed on the bottom surface part (10a) with the position aligned in the vehicle width direction and placed on the peripheral surface bottom part (5a), and the front-rear width of the insertion hole (9) is , Insertion piece (12) The circumferential surface of the front edge (9a) of the insertion hole (9) is formed as an inclined surface corresponding to the inclination of the insertion piece (12) corresponding to the maximum opening position of the grab box door (10). When the grab box door (10) is opened, the insertion piece (12) is inserted into the insertion hole (9), and the top and bottom of the projecting fulcrum part (14) is moved in a state where the back and forth movement is restricted. As the fulcrum, the grab box door (10) tilts in conjunction with the rotation, or according to claim 3, the grab box (30A) protrudes from the bottom part (30a) and extends in the vehicle width direction. And a convex portion (34) having an arc-shaped cross section centered on the rotation center axis (O) set above the bottom surface portion (30a) and corresponding to the convex portion (34) facing the bottom surface portion (30a). The bottom of the peripheral surface of the front opening (5) as a recess having an arcuate cross section ( a receiving portion (35) formed in a), an insertion piece (32) projecting from the bottom surface portion (30a) with its position shifted in the vehicle width direction with respect to the convex portion (34), and a bottom surface of the circumferential surface An insertion hole (29) formed in (5a) into which the insertion piece (32) is inserted, and bending flexure in the vehicle width direction, thereby flexing narrowly and releasing the bending when inserted into the insertion hole (29). And a locking claw (33) formed integrally with the insertion piece (32) so as to be locked around the side edge (29c) of the insertion hole (29), before and after the insertion hole (29). The edge is positioned corresponding to the rotation path of the insertion piece (32) accompanying the rotation of the grab box door (30) from the closed position to the maximum open position, and the grab box door (30) is opened. And the grab box door (30) has the convex part (34) sliding on the receiving part (35). Thus, the rotation center axis O is the center.

  As a result, the grab box (10A; 30A) is assembled to the instrument panel body by inserting the insertion piece (12; 32) into the insertion hole (9; 29), and the opening and closing thereof are inserted into the insertion hole ( 9) By rotating around the top of the projecting fulcrum (14) with the insertion piece (12) inserted into the insertion piece (12) being restrained from moving back and forth, or by sliding the receiving part (35) This is done by turning the convex portion (34) about the rotation center axis (O).

Reduction is possible. Further, the assembling work can be performed only by inserting the insertion piece without assembling to the receiving portion from a specific direction which does not come out of the hinge pin, or by making the receiving portion a special structure. According to the invention of claim 2, the grab box door is prevented from coming off when it is forcibly pulled. According to the invention of claim 3, the same effect as that of the invention of claim 1 can be obtained. At the same time, according to the invention of claim 4, the grab box door is prevented from coming off.

  A hinge structure of an automobile grab box door according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 4, a grab box 10 </ b> A is accommodated along the peripheral surface of the front opening 5 formed in the front of the main body of the instrument panel 1, and the grab box door 10 is closed in the instrument state. It is unlocked when the handle 11 (see FIG. 4) provided in the concave portion at the top of the grab box door 10 is operated with a finger to be unlocked and further rearward. When pulled, it pivots backward with its lower end as a fulcrum and opens.

  As shown in FIGS. 1 to 4, the hinge structure for rotatably supporting the grab box door is directed downward by integral molding with the bottom surface portion 10 a of the grab box 10 </ b> A that is the lower end portion of the grab box door 10. And a pair of plate-like insertion pieces 12 on both sides aligned in the vehicle width direction, and the bottom of the peripheral surface of the front opening 5 facing the bottom face portion 10a so that the insertion pieces 12 are inserted. 5a is formed integrally with the insertion piece 12 in the bottom surface portion 10a and the insertion piece 12 in the bottom surface portion 10a by aligning the positions in a row in the vehicle width direction and bulging downward to form the circumferential bottom portion 5a. And a projecting fulcrum portion 14 having a curved cross section.

  The protruding fulcrum portion is set to a protruding shape that does not cause the bottom surface portion 10a to interfere with the peripheral surface bottom portion 5a when the grab box door 10 is opened. The length of the insertion piece 12 is such that the protruding fulcrum portion 14 can protrude downward in a direction orthogonal to the circumferential surface bottom portion 5a beyond the thickness of the insertion hole 9 in a state where the protruding fulcrum portion 14 is placed on the circumferential surface bottom portion 5a. Is set. The back surface of the insertion piece 12 bends in the same plane as the insertion piece 12 when inserted into the insertion hole 9, and when the insertion is completed, the bending is released and locked to the periphery on the back side of the rear edge 9 b of the insertion hole 9. As shown, a plate-like locking claw 13 that extends obliquely rearward upward and exhibits bending elasticity in the front-rear direction is integrally formed.

  The insertion hole 9 has a rectangular shape that is wide in the vehicle width direction corresponding to the insertion piece 12, and is formed with a front-rear width that can restrict the front-rear movement of the insertion piece 12 at the front edge 9 a and the rear edge 9 b. The peripheral surface of the edge 9b is orthogonal to the plate-shaped peripheral surface bottom 5a when the door is closed, and the peripheral surface of the front edge 9a is an insertion piece corresponding to the maximum open position of the grab box door 10 (see FIG. 3). Corresponding to the inclination of 12 of about 45 °, for example, it is formed as a tapered inclined surface 9c that gradually decreases the plate thickness toward the rear.

  The operation of the hinge structure of the grab box door configured as described above is as follows. As shown in FIG. 4, the grab box 10 </ b> A is integrally manufactured by injection molding as a separate body from the instrument panel body, and the insertion piece 12 is engaged with the insertion hole 9 in the vicinity of the maximum open position shown in FIG. 3. Are inserted while being bent in the same plane, and the latching claw 13 enters the back side of the rear edge 9b and is assembled in a state where the bending is released. As a result, the grab box door 10 is held in a locked state by a normal locking mechanism (not shown) provided around the front opening 5 at the upper end in the closed position shown in FIG. 12 is inserted in the insertion hole 9 in the orthogonal direction and is close to the peripheral surface of the rear edge 9b. At that time, the front end of the locking claw 13 is prevented from coming off by being close to the periphery of the rear edge 9b.

  When the handle 11 is unlocked by its unlocking operation and pulled backward, the grab box door 10 is in a state where the insertion piece 12 inserted into the insertion hole 9 is restrained from swinging back and forth or laterally. With the top of the projecting fulcrum 14 as a fulcrum, the pin 12 is slightly moved slightly in the front-rear direction according to the sharpness of the top shape and rotated, and the insertion piece 12 tilts in conjunction.

  Thus, the protruding fulcrum portion 14 is smoothly opened in a state where it is stably placed on the peripheral surface bottom portion 5a due to the weight of the grab box 10A and the weight of the stored item. Even if the grab box 10 </ b> A is pulled obliquely upward at an intermediate open position, the locking claw 13 is prevented from coming off by being back-turned around the rear edge 9 b of the insertion hole 9. As shown in FIG. 3, the grab box door 10 is provided between the front opening 5 and the grab box 10A at an inclined position where the insertion piece 12 is close to the tapered inclined surface 9c of the front edge 9a of the insertion hole 9. It is constrained by a stopper (not shown) and is in a maximum open state.

  In the above-described embodiment, the grab box 10A is positioned by the insertion piece 12 inserted into the insertion hole 9 due to its own weight and the weight of the stored item, and is stably placed in the front opening 5. As a result, the retaining pawl 13 for retaining can be abolished in some cases on the assumption that the insertion piece 12 has a length that reaches the back surface of the circumferential bottom 5a in the rotation range. Moreover, the insertion piece 12 can also be considered as a modification in which the width is increased to one in the center, the number or shape of the projecting fulcrum portions 14 is changed, or the section is triangular. When the insertion piece 12 is formed in a plate shape, it is easy to form the locking claws on the back surface, but in some cases, it may be formed in another cross-sectional shape such as a round bar shape.

  5 and 6 show a hinge structure according to another embodiment. Similarly, the bottom portion 30a of the grab box 30A, which is the lower end portion of the grab box door 30 housed in the front opening 5, is arranged in the vehicle width direction. A convex portion 34 (FIG. 6A) having an arcuate cross section centering on the rotation center axis O which is provided in a pair projecting downward on both sides and is set along the vehicle width direction at an upper position thereof, and a bottom surface portion A receiving portion 35 (FIG. 6B) formed as a concave portion having an arc-shaped cross section corresponding to the convex portion 34 on the peripheral bottom portion 5a facing 30a and a pair of convex portions 34 from the rotation center axis O to the peripheral position at the door closing position. An insertion piece 32 projecting along a radial direction orthogonal to the surface bottom 5a, an insertion hole 29 formed in the circumferential bottom 5a so that the insertion piece is inserted, and bending elasticity in the vehicle width direction. Presenting the insertion hole 29 A locking formed integrally with the insertion piece 32 so that it bends narrowly when inserted, and is released in the insertion completed state and is locked to the back side of the side edge 29c of the insertion hole 29 in the vehicle width direction. A cross-sectional circle centering on the rotation center axis O so that the locking claw 33 is locked along the rotation path on both sides of the claw 33 and the insertion hole 29 on the back surface of the circumferential bottom 5a in the vehicle width direction. And a convex locking portion 36 formed in an arc shape.

  All the convex portions 34 and the receiving portions 35 are aligned along the rotation center axis O in the vehicle width direction and are bulged and formed into a horizontally long block shape. The pair of insertion pieces 32 are also aligned with each other along the rotation center axis O, and the insertion holes 29 and the convex locking portions 36 are the same.

  The lateral width of the insertion hole 29 corresponds to the plate-like insertion piece 12, and the front and rear width thereof is a square shape corresponding to the amount of rotation of the insertion piece 32, and the rear edge 29 b restricts the forward rotation of the insertion piece 32. Further, the front edge 29a is set corresponding to a maximum rearward opening position of about 45 °, for example.

  The insertion piece 32 is formed with a notch 32 a so as to give the locking claw 33 bending elasticity in the vehicle width direction, and the vertical position of the locking claw 33 is close to the convex locking portion 36. And is set to rotate.

  By the unlocking and opening operation of the grab box door 30, the convex portion 34 is rotated while sliding on the receiving portion 35, and the locking claw 33 is also interlocked with each other along the convex locking portion 36 that is concentric with each other. The grab box door 30 rotates about the rotation center axis O, and reaches the maximum open position where the insertion piece 32 is restrained by a stopper (not shown) at a position close to the rear edge 29b of the insertion hole 29. It can be turned. In the door closed position, the convex portion 34 is placed in an engaged state with the receiving portion 35 due to the weight, and the insertion piece 32 is restricted from rotating forward by the rear edge 29b to be in a stable locked state. .

  In the above-described embodiment, by forming the convex locking portion 36 having a circular arc cross section on the back surface of the peripheral surface bottom portion 5a, it is possible to reliably prevent the rattling of the grab box 30A, particularly in the middle of opening. However, the convex portion 34 is engaged and pressed against the receiving portion 35 due to the weight of the grab box 10A and the weight of the stored item, and therefore the locking claw 33 does not darely form the convex locking portion. It is also possible to be able to be locked directly on the flat bottom surface of the peripheral surface bottom 5a. In addition, the number of convex portions 34 or insertion pieces 32 that are aligned in the vehicle width direction and project downward from the bottom surface portion of the grab box can be changed depending on circumstances.
