A lock arm that holds the lid in a state in which the opening is closed when the other end engages with the lid body, and the planar shape of the lock arm viewed from the outer surface of the lid is rectangular. It is characterized by being formed in a frame shape.

The storage cover according to claim 2 is the storage cover according to claim 1, wherein the lid main body includes a first lock protrusion that engages with one end of the lock arm, and another end of the lock arm. An engaging second lock protrusion, and one end of the lock arm engaged with each other and the mutually opposing surfaces of the first lock protrusion are orthogonal to these contact and separation directions and The other end portion of the engaged lock arm and the mutually opposing surfaces of the second lock projection are orthogonal to these contact / separation directions .

  According to the storage cover of the first aspect, both end portions of the lock arms that engage with the lid main body protrude from the lid body. For this reason, when one of the both ends of the lock arm is engaged, the other can be easily operated.

  According to the storage cover of the second aspect, since the lock projection is provided on the lid body, both ends of the lock arm can be reliably engaged with the lid body.

  According to the first aspect of the present invention, when one of the both ends of the lock arm is engaged, the other can be easily operated. The lock arm can be deformed in the direction in which the engagement is released. Therefore, the engagement of the both ends of the lock arm with the lid body can be easily released, and the lid can be easily opened and closed.

  For this reason, even if the other end of the lock arm is once engaged with the lid body and the lid has closed the opening, the one end of the lock arm is operated to engage the other end. Can be released easily. Therefore, the opening can be easily opened.

  As described above, even if both ends of the lock arm are configured to be difficult to be detached once engaged with the lid, the engagement of these ends can be easily released by operating the ends of the lock arm. Therefore, it is possible to easily release the open and closed states while reliably maintaining the open state and the closed state of the lid.

The second lock protrusion 17 has a flat surface 17 b that is orthogonal to the peripheral wall 14 and parallel to the ceiling wall 13 at the edge on the side away from the ceiling wall 13. The flat surface 17b is orthogonal to a direction S2 (indicated by an arrow in FIGS. 3 and 4) that is relatively close to and away from the other end 12c when engaged with the other end 12c of the lock arm 12. It is formed flat along the direction.

  As shown in FIGS. 1, 2 and 5, the lid 11 is self-adjusted on one edge located between the central portion in the longitudinal direction of the ceiling wall 13 of the opening 15 and the one end described above. It is connected via the hinge 18. The self-hinge 18 is continuous with both the lid body 10 and the lid body 11, and is formed to be thinner than these so as to be freely deformable.

  The lid body 11 is supported so as to be rotatable with respect to the lid body 10 around the self hinge 18 as a result of the deformation of the self hinge 18. The lid 11 rotates around the self-hinge 18 so that the opening 15 is closed (shown in FIG. 2) and the opening 15 is opened (shown in FIG. 5). Displaceable. That is, the lid 11 can open and close the opening 15.

  The lock arm 12 is formed in a frame shape having a rectangular planar shape. Each of the lock arms 12 is connected to each of the outer surfaces of the lid body 11 that is substantially flush with the peripheral wall 14 described above when the lid body 11 is positioned in the closed state described above. As for the lock arm 12, the center part 12a of the longitudinal direction is integrally formed with the outer side surface mentioned above of the cover body 11. As shown in FIG. Both end portions 12 b and 12 c of the lock arm 12 protrude from the lid body 11. The lock arm 12 is arranged such that its longitudinal direction is orthogonal (crossed) to the surface of the lid 11.

  For this reason, when the lid body 11 rotates around the self hinge 18, the lock arm 12 has a position where the one end portion 12 b on the side away from the terminal portion 2 engages with the first lock protrusion 16, and the terminal portion 2. The near end 12c is displaced over a position where it engages with the second lock protrusion 17. Thus, the lock arm 12 has one end 12b engaged with the first lock protrusion 16 (ie, the lid body 10), and the other end 12c engaged with the second lock protrusion 17 (ie, the lid body 10). . When the one end portion 12b is engaged with the first lock protrusion 16 (that is, the lid body 10), the lock arm 12 keeps the lid body 11 in a state where the opening portion 15 is opened, and the other end portion 12c is the second end portion 12c. When engaged with the lock protrusion 17 (that is, the lid body 10), the lid body 11 is maintained in a state in which the opening 15 is closed.

  When the engagement of the one end portion 12b with the first lock projection 16 is released with the one end portion 12b engaged with the first lock projection 16 (ie, the lid body 10), the lock arm 12 Since 12a is connected to the lid 11, the other end 12c is pressed in a direction in which the other ends 12c of the pair of lock arms 12 approach each other. And the one end part 12b of the lock arm 12 is released | separated from the surrounding wall 14, and engagement with the 1st lock | rock protrusion 16 of this one end part 12b is cancelled | released. Thus, since the central portion 12a of the lock arm 12 is connected to the lid 11, the other end portion 12c of the lock arm 12 is separated from the first lock projection 16 or the peripheral wall 14 at one end portion 12b of the lock arm 12. The lock arm 12 is pressed in the direction in which the lock arm 12 is deformed, and the engagement of the one end portion 12b of the lock arm 12 with the first lock protrusion 16 is released.

  When the other end 12c is engaged with the second lock protrusion 17 (that is, the lid body 10) and the other end 12c is released from the second lock protrusion 17, the lock arm 12 is Since the central portion 12a is continuous with the lid body 11, the one end portion 12b is pressed in a direction in which the one end portions 12b of the pair of lock arms 12 approach each other. Then, the other end portion 12c of the lock arm 12 is separated from the peripheral wall 14, and the engagement of the other end portion 12c with the second lock protrusion 17 is released. Thus, since the central portion 12a of the lock arm 12 is connected to the lid body 11, the one end portion 12b of the lock arm 12 is separated from the second lock projection 17 or the peripheral wall 14 from the other end portion 12c of the lock arm 12. The lock arm 12 is pressed in the direction in which the lock arm 12 is deformed, and the engagement of the other end 12c of the lock arm 12 with the second lock protrusion 17 is released.

It is orthogonal to the contact / separation direction S1. As described above, when the first lock protrusion 16 and the one end portion 12b of the lock arm 12 are engaged with each other, the surfaces 12d and 16b facing each other are orthogonal to the contact / separation direction S1 described above. 12b and the 1st lock | rock protrusion 16 are formed in the complete lock shape which mutual engagement is very hard to remove | deviate.

  Furthermore, when the other end portion 12c of the lock arm 12 is engaged with the second lock protrusion 17, a surface 12e (shown in FIG. 4) facing the above-described flat surface 17b of the other end portion 12c of the lock arm 12 is It is orthogonal to the aforementioned contact / separation direction S2. As described above, the surfaces 12e and 17b facing each other when the second lock protrusion 17 and the other end portion 12c of the lock arm 12 are engaged with each other are perpendicular to the contact / separation direction S2 described above. The end portion 12c and the second lock protrusion 17 are formed in a complete lock shape that is very difficult to disengage from each other.

  According to the present embodiment, both end portions 12 b and 12 c of the lock arm 12 that engage with the lid body 10 protrude from the lid body 11. For this reason, when one of the both end portions 12b and 12c of the lock arm 12 is engaged, the other can be easily operated. For this reason, for example, the lock arm 12 can be deformed in a direction in which the other is easily released by operating the other. Therefore, the engagement of the both end portions 12b and 12c of the lock arm 12 with the lid body 10 can be easily released, and the lid body 11 can be easily opened and closed.

  For this reason, the lock protrusions 16 and 17 are formed in the above-described complete lock shape, and in particular, the other end portion 12c of the lock arm 12 is once engaged with the second lock protrusion 17 provided on the lid body 10, Even when the lid 11 closes (closes) the opening 15, the one end 12b of the lock arm 12 can be operated to easily disengage the other end 12c. Therefore, the opening 15 can be easily opened.

  As described above, even if both ends 12b and 12c of the lock arm 12 are configured to be difficult to be detached once engaged with the lid body 11, by operating the ends 12b and 12c of the lock arm 12, these ends 12b and 12c The engagement of 12c can be easily released. Therefore, it is possible to easily release the closed state and the closed state while enabling the lid 11 to be reliably maintained in the opened state and the closed state.

  Further, since the lock projections 16 and 17 are provided on the lid main body 10, both end portions 12 b and 12 c of the lock arm 12 can be reliably engaged with the lid main body 10. Therefore, the lid 11 can be reliably positioned in both the opened state and the closed state of the opening 15.
