  The covering wall 25 protrudes from the surface of the lower step wall 24, and a support groove 27 is formed between the covering wall 25 and the wall of the rising portion from the lower step wall 24 to the upper step wall 23 in the step portion 12a. is there.

5A and 5B are diagrams showing an operation handle of the lid opening / closing operation device, wherein FIG. 5A is a top view, FIG. 5B is a front view, and FIG. 5C is a side view.
As shown in FIG. 5, the operation handle 30 has an operation plate 31, a support shaft 32 extending from both side edges of the operation plate 31, and a hook portion 33 extending from the center of the edge of the operation plate 31. Yes. A pair of spring piece abutting portions 34 are formed on both sides of the hook portion 33 at the front end edge of the operation plate 31. On the other hand, the rear edge of the operation plate 31 and its peripheral part constitute an operation unit 35. The operation portion 35 and the spring piece abutting portion 34 are provided on opposite sides with a rotation axis passing through the pair of support shafts 32 as a boundary.

6A and 6B are cross-sectional views showing the overall structure of the lid opening / closing operation device in which the operation handle is assembled to the main body. FIG. 6A is a side cross-sectional view on the same line as FIG. 4A, and FIG. It is side surface sectional drawing on the same line as b).
The operation handle 30 has a support shaft 32 supported by the bearing 16 of the main body 10, and is rotatable about the support shaft 16. The surface of the operation plate 31 is disposed substantially flush with the opening surface of the recess 15 in the main body 10. The user inserts a finger into the recess 15 of the main body 10 and rotates the operation portion 35 of the operation handle 30 from the inside of the recess 15.

Yes. At this time, the spring piece 18 is slightly bent, and thereby, a rotational biasing force is applied to the spring piece abutting portion 34 from the spring piece 18. The operating handle 30 is stationary without rattling because the leg portion of the hook portion 30 abuts against the opening edge 17a of the main body 10 with this rotational biasing force (see FIG. 6A).

  Here, the spring piece abutting portion 34 is in contact with an intermediate portion between the free end 19 of the spring piece 18 and the curved portion. Further, since the free end 19 ahead of the abutting portion extends into the cutout hole 20 of the main body 10, the spring piece abutting portion 34 is moved by the deflection or vibration of the spring piece 18. Therefore, the spring piece abutting portion 34 can be urged stably.

  Further, since the pair of spring pieces 18 uniformly urges the spring piece abutting portions 34 at the left and right symmetrical positions, the operation handle 30 does not apply a biased load to each of the support shafts 32 and can smoothly rotate. Dynamic operation can be realized.

  A contact portion 36 is formed on the front edge of the operation handle 30 on the side of the spring piece contact portion 34. On the other hand, as shown in FIG. 7, stoppers 23 a for the operation handle 30 are formed on the inner edges of both sides of the upper wall 23 in the main body 10.

FIG. 8 is a side cross-sectional view illustrating a procedure for attaching the lid opening / closing operation device to the lid.

The lid opening / closing operation device is attached to the lid 100 by first putting the covering wall 25 into the attachment port 101 and then inserting one end edge of the attachment port 101 into the support groove 27 formed in the lower wall 24 of the main body 10 (FIG. 8 ( b)), the main body 10 is rotated with the support groove 27 as a fulcrum, and the second locking portion 22a is aligned with the other end edge of the mounting port 101 (see FIG. 5C).
Next, the main body 10 is slid downward in FIG. 8 to engage the second locking portion 22a with the other end edge of the mounting port 101, and further, the main body is rotated using the second locking portion 22a as a fulcrum. The upper wall 23 is fitted into the attachment port 101, and the first locking portion 21a is engaged with one end edge of the attachment port 101 (see FIG. 4D). Thereby, the main body 10 is attached to the attachment port 101.

9A and 9B are side cross-sectional views showing a state in which the storage space is closed by the lid according to the present embodiment, where FIG. 9A is a state before the operation handle is rotated, and FIG. 9B is a state after the operation handle is rotated. Each state is shown.
When the lid 100 is fitted into the opening 201 of the accommodation space 200 shown in FIG. 2 and the opening 201 is closed, as shown in FIG. The edge portion 33a is hooked and locked to the peripheral edge portion (locking portion) of the locking port 202 previously formed in the peripheral edge of the opening 21. In this way, the hook 100 is locked to the peripheral edge of the locking port 202, so that the lid 100 can maintain the closed state of the opening 201.

  When removing the lid 100 from the opening 201, as shown in FIG. 9B, a finger is hooked on the operation portion 31 of the operation handle 30 from within the recess 15 of the main body 10, and the operation handle 30 is centered on the support shaft 32. Rotate clockwise in the figure. By this operation, the hook portion 33 is also rotated in the same direction, and the engagement with the peripheral edge portion of the locking port 202 is released. Thereby, the lid 100 can be removed from the opening 201 of the accommodation space 200 and the opening 201 can be opened.

  Here, at the end position of the rotation operation, the contact portion 36 formed on the front edge of the operation handle 30 contacts the stopper 23a of the main body 10, and further rotation is prevented.

  As described above, the body 10 of the lid opening / closing operation device is provided with the covering wall 25 along the opening edge of the outer peripheral surface. As shown in FIG. 9 (b), the covering wall 25 has a hooking edge portion 33 a of the hook portion 33 when the hook portion 33 is in a rotational position for releasing the engagement with the peripheral edge portion of the locking port 202. Is configured to cover both sides. Thereby, in the turning operation of the operation handle 30, there is no possibility that the covering edge 25 of the hooking portion 33 of the covering wall 25 is caught again on the peripheral edge portion of the locking port 202, and the removal operation of the lid 100 is not hindered. It becomes possible to execute smoothly.

  Further, by the turning operation of the operation handle 30, the spring piece abutting portion 34 of the operation handle 30 presses and bends the spring piece 18. For this reason, the spring piece 18 gives a rotation biasing force in the opposite direction to the spring piece abutting portion 34. Therefore, when the finger is released from the operation handle 30, the operation handle 30 is rotated counterclockwise in FIG. 9 by the rotation biasing force from the spring piece 18, and the original rotation shown in FIG. Return to position.

  Here, as shown in FIG. 10, the rotational biasing force by the spring piece 18 increases in proportion to the amount of deflection and the magnitude of the spring constant. As described above, the spring piece 18 of the present embodiment has a small spring constant by forming a long spring length. That is, the spring piece 18 of the present embodiment is configured such that the proportional relationship between the rotational biasing force and the deflection gradually increases. In this way, by reducing the rotational biasing force of the spring piece 18, the operation handle 30 can be pulled with a light force from the start to the end of pulling, and good handle operability can be obtained.

  In addition, this invention is not limited to embodiment mentioned above, Of course, a various modification and application example are possible. For example, the spring piece 18 is not limited to the U-shaped curve as in the present embodiment, but may be formed in a curved shape in an L shape extending from the bottom wall 11 toward the front wall 12.
