PURPOSE: To mount a door easily by a method wherein a shaft pin is inserted from the lower side of the bearing section of a column-side slat while energizing a shaft-pin upper-end inserting section in the direction of projection in a freely projecting and retreating manner, and the inserting section is projected and retreated and inserted into the bearing of a door-side slat.
CONSTITUTION: A collar section 41 is gripped and pulled against the energizing force of a resilient spring 5 in the direction of non-junction in a shaft pin 4 inserted into the bearing section 3 of a slat 2 installed to a column 1, and an inserting section 43 is sunk from the junction-side end face 36 of the bearing section 3. The collar 41 is rotated centering around an axial center, a projection- shaped engaging section 44 formed to the pin 4 is engaged with the stepped engaging section 32 of a tubular member 11 fixed into the bearing 3, and the state of the sinking of the pin 4 is maintained. The bearing section 8 of a slat 7 set up onto the door 6 is superposed on the bearing 3. The collar 41 is turned, the engagement of the engaging sections 32, 44 is released, the inserting section 43 is inserted into the bearing 8, and the slats 2, 7 are attached pivotally. Accordingly, the door can be mounted without lifting, and appearance can be improved because a shaft-pin operating member is not exposed to the outside.
