成して、位置決めするようにしても良い。When the shaft pin 30 is inserted into the shaft hole 12, if there is no positioning means, an assembling worker can easily make a mistake in the fitting direction of the shaft pin 30, and if the inserting direction is misaligned, the locking projection is engaged. It may be displaced from the hole and may not be properly fitted and locked in the engagement hole. If the shaft pin is not securely locked, the shaft pin may be easily removed. The assembling operator must confirm whether or not the locking projections of the shaft pins of the hinge portions at a plurality of positions are locked in the receiving holes. Therefore, FIGS. 8, 12 and 14 show an embodiment in which a positioning means is provided to facilitate the alignment of the engagement hole 13 and the locking projection 33 when the shaft pin 30 is inserted into the shaft hole 12. It was That is, as a positioning means, a guide projection 14 is formed in the upper center of the shaft hole 12 of the bearing portion 11 of the one plate body 10, and the upper surface of the shaft pin 30 has substantially the same width as the central slit 31 from the front end to the rear end. The guide groove 35 is formed on the same line as the slit. By providing the guide groove and the guide protrusion, the bearing portions 11 and 21 of the plate bodies 10 and 20 are adjacent to each other on the same axis and the shaft pin 30 is provided.
At the time of inserting, by simply aligning and pressing the guide groove 35 with the guide protrusion 14, the shaft pin 30 can be positioned in the shaft holes 12 and 21, and the locking protrusion 33 can be accurately locked in the engaging hole 13. The work efficiency can be improved. This guide groove 3
Since 5 is provided in the entire axial pin in the axial direction, it is possible to prevent sinkholes (distortion) from being generated at the time of molding the pin, instead of forming a through hole in the center of the shaft. Although the embodiment has shown the case where the guide protrusion is provided in the shaft hole and the guide groove is provided in the shaft pin, the present invention is not limited to this, and the guide groove is formed at the inlet on the shaft hole side and the guide protrusion is provided on the shaft pin side. It may be formed and positioned.

Are provided at symmetrical positions. Similarly to the above, the axial pin 30 is formed with a bifurcated end portion 32 by forming a slit 31 in the axial direction from the tip to the back of the position of the receiving hole 13 at the center of the end portion to form a bifurcated end portion 32. Correspondingly, locking projections 33, 33 are formed at symmetrical positions as locking means on both sides of the outer circumference of the end portion 32. In addition, the mountain-shaped locking protrusions 33 are engaged holes 1
The size should be such that it can engage with 3. Since it is locked on both sides, the locking projection 33 is formed to have a slightly lower height. When inserting the shaft pin, if the inclined surfaces of the locking projections 33, 33 on both sides are pressed, the end 32 at the tip of the shaft pin is elastically pinched, and the locking projections 33 on both sides engage. It is locked in the receiving hole 13 by a restoring force. In the case where the locking projections 33 are provided on both sides of the shaft pin 30, since the shaft pin 30 is bilaterally symmetric, it can be inserted even if the shaft pin is left-right reversed. Further, if the guide grooves 35 are provided symmetrically above and below the shaft pin, one of the guide grooves of the shaft pin can be inserted into the guide protrusion 14 of the shaft hole when the shaft pin 30 is inserted. It is convenient for

The other plate such as the upper plate, the tilt plate, and the lower plate can be freely undulated with respect to one plate such as the upper plate and the bottom frame. Therefore, the hinge part of the folding transport container,
It is the most suitable structure for use in the hinge of other openable containers. Further, since the end portion of the shaft pin can be pinched and easily pulled out from the shaft hole, when the shaft pin is damaged or deformed, it can be easily replaced, which is convenient.
