Claims

[Claims for Utility Model Registration] A pair of support arms 11, 11 provided on the door 4 with an interval between them have bearing holes 13, 13 coaxially formed with open sides facing each other. The synthetic resin frame 3 having an opening 5 to be closed with the door 4 is provided with the bearing hole 13,
A pair of regulating bearing parts 15, 15 having through holes 14, 14 coaxial with 13 are attached to the side surfaces of both support arm parts 11, 11 on the inner side along the axis of the through holes 14, 14 and the bearing holes 13, 13. The outer ends in the axial direction of the pair of support shafts 12, 12, which are protrudingly provided to face each other and are inserted into the through holes 14, 14, respectively, are connected to the respective bearing holes 13,
In the door opening/closing support structure inserted in 13,
Along the axis of the support shafts 12, 12, both regulating bearings 15
, 15, a pair of inner end bearing portions 16, 16 are protruded from the frame body 3 at positions spaced inwardly from the frame body 3,
Regulation bearing parts 15, 15 and inner end bearing parts 16, 1
Both ends of torsion springs 18, 18 surrounding each support shaft 12, 12 between 6 and 6 are respectively engaged with the door 4 and the frame 3 in order to bias the door 4 in the opening direction, and each of the inner end bearing portions At the tips of the torsion springs 18, 15, there are bearings whose tips are open to receive the inner end surfaces of the spindles 12, 12 only in the direction in which the reaction force of the torsion springs 18, 18 acts on the spindles 12, 12. Surface 17
, 17 are respectively formed. A synthetic resin cover 22 that is removably attached to the frame 3 to cover the frame 3 between the support arms 11, 11 has a cover 22 that restricts the inward movement of the support shafts 12, 12 in the axial direction. In order to
a pair of regulating protrusions 27 that can come into contact with the axially inner end of the
27. The door opening/closing support structure according to claim 1, wherein the door opening/closing support structure is characterized in that the number 27 is provided in a protruding manner.
