[0011] The base portion 2 has a base storage portion 23 that stores a first tool. The first tool is, for example, a power tool used for tightening a fastening part (screw, bolt, nut, etc.) to a work object (electrical appliance, furniture, etc.). Note that the first tool may be a power tool used for drilling a hole in a work object or cutting the work object, and the use of the power tool is not limited.

[0012] The inner lid 3 is rotatably connected to the base part 2, opens and closes by rotating relative to the base part 2, and has an inner lid storage part 33 that covers at least a part of the base storage part 23 when closed and stores a second tool. The second tool is, for example, a bit, a fastening part, or a battery pack attached to a power tool. A user of at least one of the first tool and the second tool (hereinafter, referred to as a user) takes out at least one of the first tool and the second tool from the tool box 1 to use it, and stores at least one of the first tool and the second tool back in the tool box 1 after use.

[0013] The outer lid 4 is rotatably connected to the inner lid 3, and opens and closes by rotating relative to the inner lid 3, and covers at least a portion of the inner lid storage section 33 when in a closed state.

[0014] The first locking portion 5A detachably fixes the outer lid 4 to the inner lid 3. When the outer lid 4 is fixed to the inner lid 3 by the first locking portion 5A, the outer lid 4 cannot rotate with respect to the inner lid 3 while covering at least a portion of the inner lid storage portion 33.

[0015] Similarly, the second locking portion 6A detachably fixes at least one of the inner lid 3 and the outer lid 4 to the base portion 2. When at least one of the inner lid 3 and the outer lid 4 is fixed to the base portion 2 by the first locking portion 5A, at least one of the inner lid 3 and the outer lid 4 becomes unable to rotate with respect to the base portion 2 while covering at least a portion of the base storage portion 23.

[0016] The lid opening operation unit 7 rotates the inner lid 3 together with the outer lid 4 relative to the base unit 2 while the outer lid 4 is fixed to the inner lid 3 by the first lock unit 5A, thereby opening the inner lid 3 and the outer lid 4 together. In the first embodiment, the base unit 2 has a notch 71 provided on an edge portion that contacts the inner lid 3. With the outer lid 4 fixed to the inner lid 3 by the first lock unit 5A, the user can rotate the inner lid 3 together with the outer lid 4 relative to the base unit 2 and open the inner lid 3 and the outer lid 4 simultaneously by inserting a finger into the notch 71 and pushing up the inner lid bottom surface 31 described later. That is, the notch 71 functions as the lid opening operation unit 7. In other words, the lid opening operation unit 7 includes the notch 71.

[0017] As described above, the toolbox 1 of embodiment 1 has an advantage in that it is easier to open the inner lid 3 and the outer lid 4 together, since it is equipped with a lid opening operation section 7 that opens the inner lid 3 and the outer lid 4 together.

[0051] For example, when there are three cutout portions 71, two of the three cutout portions 71 are provided in positions facing each other in the axial direction in which the inner lid 3 rotates in the base portion 2. In other words, when there are three cutout portions 71, the three cutout portions 71 include two cutout portions 71 provided in positions facing each other in the base portion 2 along the axial direction in which the inner lid 3 rotates.

[0052] There may be only one cutout portion 71 in the first embodiment. In this case, one cutout portion 71 is provided on an edge portion that contacts the inner lid 3 when the inner lid 3 is in a closed state on any one of the base front surface 221, the base rear surface 222, the base right surface 223, and the base left surface 224. That is, the cutout portion 71 is provided at a position adjacent to the base opening on any one of the base front surface 221, the base rear surface 222, the base right surface 223, and the base left surface 224.

[0053] In the first embodiment, the direction in which the outer lid 4 rotates relative to the inner lid 3 is the same as the direction in which the inner lid 3 rotates relative to the base part 2. However, the direction in which the outer lid 4 rotates relative to the inner lid 3 may be different from the direction in which the inner lid 3 rotates relative to the base part 2. For example, the second inner lid connecting parts 36a, 36b may be provided on the inner lid left surface 324, the outer lid connecting parts 43a, 43b may be provided on the left end part of the outer lid 4, and the outer lid 4 may rotate with the front-rear direction as the axial direction relative to the inner lid 3. Also, the first inner lid connecting parts 35a, 35b may be provided on the inner lid left surface 324, and the base connecting parts 26a, 26b may be provided on the edge part of the base left surface 224 that contacts the inner lid 3, and the inner lid 3 may rotate with the front-rear direction as the axial direction relative to the base part 2.

[0054] Although the base bottom surface 21 of the first embodiment has the base partitioning portion 24, the base bottom surface 21 may not have the base partitioning portion 24. In that case, the base storage portion 23 is not divided by the base partitioning portion 24.

[0055] Similarly, although the inner lid bottom surface 31 of the first embodiment has the inner lid partition portion 34, the inner lid bottom surface 31 may not have the inner lid partition portion 34. In that case, the inner lid storage portion 33 is not partitioned by the inner lid partition portion 34.

[0056] The second through-hole 92A in the first embodiment is provided in the handle attachment portion 81A of the base front surface 221, but may be provided directly in the base portion 2.

[0057] In the first embodiment, the base storage section 23 stores the first tool, and the inner lid storage section 33 stores the second tool. However, the base storage section 23 may store the second tool, and the inner lid storage section 33 may store the first tool.

[0058] (Embodiment 2) The tool box 1 according to the second embodiment differs from the tool box 1 according to the first embodiment in that the outer lid 4 has a recess 72 instead of the base 2 having the cutout 71.

With the outer lid 4 fixed to the inner lid 3 by the first locking portion 5A, the user can insert a finger into the recess 72 and push up at least one of the inner lid 3 and the outer lid 4. This allows the user to rotate the inner lid 3 together with the outer lid 4 relative to the base portion 2, and open the inner lid 3 and the outer lid 4 together. That is, the recess 72 of the second embodiment functions as the lid opening operation portion 7. In other words, the lid opening operation portion 7 of the second embodiment includes the recess 72.

[0061] 5 and 6, the tool box 1 of the second embodiment has two recesses 72. Since the inner lid 3 rotates about an axial direction in the left-right direction, the two recesses 72 are provided at positions on the outer lid left surface 424 and the outer lid right surface 423 such that the two recesses 72 face each other in the left-right direction.

[0062] The shape of the recess 72 in the second embodiment is a rectangular parallelepiped. However, the shape of the recess 72 may be any shape that allows a user to insert a finger and push up the lower surface of the inner lid 3. For example, the shape of the recess 72 may be a cylinder with a circular bottom surface parallel to the vertical direction, or a prism with a triangular or trapezoidal bottom surface parallel to the vertical direction.
