  • the arm portions 21 and 21 can be made non-rotatable with respect to the lid main body 10. That is, the arm portions 21 and 21 can be maintained at a predetermined rotation position with respect to the lid main body 10.
  • the second planes 21F and 21F of the arm portions 21 and 21 extend from the arcuate surfaces 21E and 21E and face the bottom surface 14A of the accommodating recess 14 when the handle 20 stands upright with respect to the lid body 10. Therefore, when the handle 20 is lifted with respect to the lid body 10, the second planes 21F and 21F of the arm portions 21 and 21 are brought into contact with the bottom surface 14A of the accommodating recess 14, so that the handle 20 is brought into contact with the lid body 10. It is held in the launched state. This makes it easier to hold the handle 20.
  • the handle 20 can be easily rotated with respect to the lid main body 10, and the lock mechanism allows the lid main body 10 to rotate.
  • the handle 20 can be maintained at a predetermined rotation position.
  • the present invention is not limited to the above embodiment, and can be appropriately modified as long as it does not deviate from the gist of the present invention.
  • the handle is provided with two arm portions, and the lock mechanism is provided for each arm portion.
  • the lock mechanism may be provided for only one arm portion, and the arm portion may be provided. May use one handle.
  • the storage recess of the lid body has been described as being open to the top surface of the lid body and the side surface of the lid body.
  • the lid body It may not be open to the side.
  • the accommodating recess 14 is open to the top surface 11A of the lid body 10A, but not to the side surface 11B of the lid body 10A. That is, both sides of the second accommodating portion 14D in the Y direction are not open to the side surfaces 11B of the lid body 10A. Therefore, recesses 15A and 15B are formed on both sides of the second accommodating portion 14D in the Y direction.
  • the recess 15A and the recess 15B are recesses recessed from the top surface 11A for hooking the handle 20A housed in the storage recess 14 with a finger or the like, similarly to the recess 15 of the above embodiment. As a result, the handle 20A can be pushed in the Y direction from the recess 15A or the recess 15B.
  • the shaft portion and the hole portion that rotatably support the handle with respect to the lid body have been described as forming the lock mechanism.
  • the locking mechanism may be configured by another element.
  • a convex portion 18 is formed on the lid body 10B separately from the shaft portion, and a concave portion 28 is formed on the handle 20 separately from the hole portion. Even in this way, the rotation position of the handle 20 with respect to the lid main body 10B can be maintained by rotating the handle 20 with respect to the lid main body 10B and fitting the convex portion 18 into the concave portion 28.
