  When the protrusion 62 bites into the upper end defining surface portion 46, the first head 60 of the bolt 50 is fixed to the upper end defining surface portion 46. That is, the bolt 50 is fixed in the groove 40.

  Since the third height H3 of the second head portion 70 has a length less than the first depth D1 of the second housing portion R2 in a state where the nut 80 is not tightened, the second height H3 is the second height H3. The accommodating portion forming portion 44 is subjected to a compressive load in the vertical direction V by tightening torque. The 2nd accommodating part formation part 44 deform | transforms with this compressive load. When the compressive load is applied in the vertical direction V as described above, the second housing portion forming portion 44 is deformed so as to move inward in the width direction. In FIG. 8, the inner surface 47 of the second housing portion forming portion 44 in a state where the nut 80 is not tightened is indicated by a two-dot chain line.

  The second housing portion forming portion 44 moves inward in the width direction, so that its inner surface 47 comes into surface contact with the seventh side surface 75 and the eighth side surface 76 of the second head 70, and the second head The portion 70 is sandwiched in the width direction W. Further, the inner surface 47 of the second storage portion forming portion 44 is parallel to the vertical direction V when the second inner surface 47 comes into surface contact with the seventh side surface 75 and the eighth side surface 76 of the second head 70.

  As described above, the gap S <b> 2 is formed so that the inner surface 47 of the second housing portion forming portion 44 is moved to the seventh side surface 75 and the second side by moving the second housing portion forming portion 44 inward in the width direction by a predetermined tightening torque. 8 is brought into contact with the side surface 76 of the surface 8 to form a plane parallel to the vertical direction V, the second storage portion forming portion 44 is parallel to the vertical direction V, and the second storage portion forming portion 44 The gap is set to generate a force for clamping the head 70 in the width direction W.

  Next, an example of the work of placing the luggage 1 on the pallet 10 will be described. FIG. 2 shows a state in which the luggage 1 is placed on the pallet 10. Note that the outline of the luggage 1 is indicated by a two-dot chain line.

  As shown in FIG. 2, first, when the luggage 1 is placed on the pallet 10, the position at which the placement member 90 is fixed on the pallet main body 20 is determined. Once the position for fixing the mounting member 90 is determined, the head 51 of the bolt 50 is then placed in the groove 40 to fix the mounting member 90 at the position.

  As shown in FIG. 5, the bolt 50 is disposed in the groove portion 40 through the opening 40 a in a posture in which the head portion 51 passes through the opening 40 a of the groove portion 40. Specifically, the head 51 is disposed in the groove 40 through the opening 40 a in a posture in which the longitudinal direction of the first head 60 of the bolt 50 is parallel to the longitudinal direction L of the groove 40.

  As shown in FIG. 4, the first head 60 is installed on the upper surface 41 a of the bottom wall 41 of the groove 40, so that the axis of the shaft 52 of the bolt 50 is parallel to the vertical direction V. In addition, a part of the first head 60 and the second head 70 are arranged in the first housing part R1, and a part of the second head 70 is placed in the second housing part R2. Be placed.

  Next, as shown in FIG. 7, the bolt 50 is connected to the axis of the shaft portion 52 so that the third side surface 68 and the fourth side surface 69 of the first head 60 face the width defining surface portion 45. Rotate around. Specifically, the bolt 50 is formed on the curved surface of the second head 70 such that the ridges C5 and C6 formed on the curved surface of the first head 60 are directed toward the width defining surface 45. The ridges C7 and C8 are rotated about the axis of the shaft portion 52 so as to go to the inner surface 47 of the second housing portion forming portion 44.

  The operator forms the third ridge C3 between the first side surface 66 and the third side surface 68 of the first head 60 by forming the ridge portions C5, C6, C7, and C8 into a curved surface, and The bolt 50 can be rotated until the fourth ridge C4 between the second side surface 67 and the fourth side surface 69 contacts the width defining surface portion 45.

  Further, the operator can determine whether or not the bolt 50 has been rotated by checking the mark 54 formed on the end surface 53 of the shaft portion 52 of the bolt 50. This is because the posture of the mark 54 indicates the posture of the head 51.

  For example, as shown in FIG. 7, when the longitudinal direction of the mark 54 is orthogonal to the longitudinal direction L of the groove portion 40, the operator can connect the bolt 50 with the longitudinal direction of the first head 60 to the groove portion 40. It can be determined that the posture is orthogonal to the longitudinal direction. Therefore, it can be determined that the third side surface 68 and the fourth side surface 69 are opposed to the width defining surface portion 45.

  In the present embodiment, the third ridge portion C3 between the first side surface 66 and the third side surface 68 and the fourth ridge portion C4 between the second side surface 67 and the fourth side surface 69 are width defining surface portions. When the bolt 50 is rotated until it comes into contact with 45, further rotation is prevented, and the longitudinal direction of the mark 54 is slightly inclined with respect to the direction perpendicular to the longitudinal direction L of the groove portion 40. .

  The bolt 50 is rotated until the first head 60 contacts the width defining surface portion 45, whereby the upper surface 65 and the protrusion 62 of the first head 60 face the upper end defining surface portion 46 in the vertical direction V. To do.

  The fifth length L5, which is the length in the longitudinal direction of the first head 60, is longer than the second length L2 between the second ridges C2 on the inner surface of the second housing portion forming portion 44. Thus, even if the bolt 50 is rotated to a posture where the longitudinal direction of the first head 60 is parallel to the width direction W, that is, the first head 60 is rotated until it abuts against the width defining surface portion 45. First, even if the longitudinal direction of the first head 60 rotates to a posture in which the longitudinal direction of the first head 60 is parallel to the width direction W based on the posture of the mark 54, the upper surface 65 and the protrusion 62 of the first head 60 are 46 is opposed to the vertical direction V.

  Next, the operator attaches the mounting member 90. The mounting member 90 is attached so that the shaft portion 52 of the bolt 50 is disposed in the through hole 91. When the mounting member 90 is attached, the operator then passes the washer 100 through the shaft portion 52 and the nut 80 is screwed into the shaft portion 52 and tightened with a predetermined tightening torque.

  When the nut 80 is tightened with a predetermined tightening torque, as shown in FIG. 8, the inner surface 47 of the second housing portion forming portion 44 is moved to the seventh side surface 75 and the eighth side surface 76 of the second head 70. And the second head 70 is sandwiched between the second housing portion forming portions 44. Further, the second accommodating portion forming portion 44 is parallel to the vertical direction V.

  The mounting member 90 is fastened and fixed to the pallet body 20 by bolts 50 and nuts 80. When the placement member 90 is fixed to the pallet main body 20, the operator then places the luggage 1 on the placement portion 93 of the placement member 90.

  FIG. 9 is a plan view showing another example of the fixing position of the mounting member 90 with respect to the pallet main body 20. As shown in FIG. 9, the posture of the mounting member 90 can be adjusted by shifting the position of the shaft portion 52 of the bolt 50 in the through hole 91.

  In the pallet 10 shown in FIG. 9, the placing member 90 is fixed to the pallet main body 20 so that, for example, a cylindrical luggage 1 can be placed. Specifically, the mounting member 90 is configured such that the alignment direction of the through holes 91 is inclined with respect to the longitudinal direction L of the groove portion 40 by adjusting the position of the shaft portion 52 of the bolt 50 in the through hole 91. Thus, the pallet body 20 is fixed.

  In the pallet 10 formed in this way, the bolt 50 can be taken in and out through the opening 40 a of the groove portion 40 of the pallet main body 20 where the mounting member 90 is fixed, and the first head 60 is the inner surface of the groove portion 40. By rotating until it comes into contact with the width defining surface portion 45, it is possible to prevent the groove portion 40 from coming off.

  For this reason, the bolt 50 does not need to be taken in and out through the opening on the peripheral surface of the pallet main body 20 of the groove portion 40, so that it is not necessary to slide the bolt 50 along the groove portion 40. Furthermore, since the bolt 50 can be prevented from coming off only by rotating until the first head 60 contacts the inner surface of the groove portion 40, the efficiency of the fixing work for fixing the mounting member 90 to the pallet main body 20. Can be improved. For this reason, the efficiency of the operation | work which mounts the luggage | load 1 on the pallet 10 can be improved.

  Moreover, the structure of the pallet 10 can be simplified by using the bolt 50 as an attachment member for fixing the mounting member 90 to the pallet body 20.

  In addition, the bolt 50 includes the second head 70 that is sandwiched between the inner surfaces 47 of the second housing portion forming portions 44 of the groove portion 40 in a state where the nut 80 is tightened with a predetermined tightening torque. Can be firmly fixed to the pallet body 20.

  Further, the second housing portion forming portion 44 of the groove portion 40 is parallel to the depth direction of the groove portion 40 when the nut 80 is tightened with a predetermined tightening torque. It becomes a plane parallel to.

  Therefore, when the load 1 is placed on the pallet 10, when a load is applied to the pallet main body 20 in the vertical direction V, that is, the depth direction of the groove 40, as described above, the second storage portion forming portion Since the function of the second accommodating portion forming portion 44 as a reinforcing rib is improved by the 44 being parallel to the depth direction of the groove portion 40, the rigidity of the pallet 10 with respect to the load input from the load 1 is improved. Can do.

  Further, since the first head 60 has the protrusion 62, the first head 60 can be firmly fixed to the groove 40.

  In addition, the operator confirms the mark 54 formed at the tip of the shaft portion 52 of the bolt 50, so that the bolt 50 is rotated to the retaining position, that is, the third of the first head 60. It is possible to easily determine whether or not the side surface 68 and the fourth side surface 69 of the groove portion 40 have been rotated to a position facing the width defining surface portion 45 of the groove portion 40, so that work efficiency can be improved. it can.

  Furthermore, by using a groove extending parallel to the longitudinal direction of the first head 60 as a mark, the posture of the first head can be easily determined.

  In addition, the through hole 91 of the mounting member 90 is formed into a long hole, so that the position of the shaft member 52 of the bolt 50 in the through hole 91 is adjusted, whereby the attitude of the mounting member 90 with respect to the pallet body 20. Can be adjusted. Therefore, the placement member 90 can be optimally arranged according to the shape of the luggage 1.

  In the present embodiment, a pallet 10 such as a pallet used for transporting luggage is used as an example of the mounting table. In another example, the mounting table may be, for example, a bottom wall portion of a container. The bottom wall portion of the container is an example of a placement table on which a load is placed. Further, the mounting table may be a table other than the pallet used for conveyance.

  Further, in the present embodiment, the mounting member 90 has the mounting portion 93 on which the object to be mounted is formed in a planar shape, but is not limited thereto. The mounting member 90 is formed in a shape suitable for mounting the mounted object. In the present embodiment, the object to be placed is placed on the placement member 90. However, as another example, the placement member 90 has a fixing structure for fixing the object to be placed to the placement member 90. May be.

  Alternatively, the mounting table does not use the mounting member 90, and the shaft portion 52 of the bolt 50 may be directly fixed to the mounting object.
