  • the first rotation support part may be provided by providing an axle on the base member side and a support hole on the opening/closing body side to support the axle rotationally, or by providing support holes on both the base member and the opening/closing body and inserting and supporting a separate shaft through these support holes.
  • the second rotation support part may be provided by providing an axle on the lock member side and a bearing part on the base member side.
  • the stopper portion may be provided only between the base member and the locking member, or between the opening/closing body and the locking member. Note that an embodiment in which the stopper portion is provided only between the base member and the locking member will be described later.
  • the engaged portion may be a convex portion and the engaging portion may be a concave portion, or both the engaged portion and the engaging portion may be projections that engage with each other.
  • the insertion member 5 is inserted into the openings 2 and 3 of the fixed member 1 along the insertion direction F1, and the insertion member 5 is inserted into the openings 2 and 3 to a predetermined depth as shown in Figures 11 and 12.
  • the tip of the insertion member 5 abuts against and is pressed against the abutment surface 65a of the abutment portion 65 of the locking member 60, causing the locking member 60 to rotate in the direction opposite to the R2 direction against the biasing force from the second arm portion 85 of the biasing member 80.
  • the abutment portion 65 is released from the insertion path F2 of the insertion member 5.
  • the engaging portion 70 of the locking member 60 comes out of the concave curved surface 58a of the engaged portion 58 of the opening/closing body 40, and the engagement between the engaged portion 58 and the engaging portion 70 is released, so that the opening/closing body 40 rotates in the R1 direction due to the biasing force from the first arm portion 83 of the biasing member 80.
  • the tip of the contact surface 65a of the contact portion 65 contacts the outer peripheral surface of the insertion member 5, restricting the rotation of the locking member 60 in the R2 direction.
  • the plug-in member 5 is pulled out from the openings 2, 3 of the fixed member 1.
  • the opening/closing body 40 to which a biasing force is applied from the first arm 83 of the biasing member 80 via the first engagement portion 54, rotates in the R1 direction to close the opening 3 again
  • the locking member 60 to which a biasing force is applied from the second arm 85 of the biasing member 80 via the second engagement portion 74, rotates in the R2 direction, and its abutment portion 65 again enters the insertion path F2 of the insertion member 5, returning to the state shown in Figures 4 and 5.
  • the engaging portion 70 of the locking member 60 abuts against the abutment end portion 57a of the groove 57 of the opening/closing body 40, and as shown in FIG. 7, the tip portion 75 and flange portion 77 of the projection 73 of the locking member 60 abut against the inner edge portion 38 of the recess 37 of the base member 20, restricting further rotation of the locking member 60 in the R2 direction (the rotation stopper functions), and preventing the locking member 60 from coming off the base member 20 (the anti-slip stopper functions).
  • the first arm 83 of the biasing member 80 is engaged with the first engagement portion 54 of the opening/closing body 40, thereby biasing the opening/closing body 40 in the R1 direction, which is the direction in which the opening/closing body 40 closes the opening 3, and the second arm 85 of the biasing member 80 is engaged with the second engagement portion 74 of the locking member 60, thereby biasing the locking member 60 in the R2 direction, which is the opposite direction to R1, which is the direction in which the opening/closing body 40 is biased, and so that the abutment portion 65 enters the insertion path F2 of the insertion member 5.
  • one biasing member 80 can bias two members, the opening/closing body 40 and the locking member 60, simultaneously, which reduces the number of parts in the opening/closing device 10 and simplifies the structure of the opening/closing device 10.
  • the rotation axis C1 of the opening/closing body 40 and the rotation axis C2 of the locking member 60 are arranged parallel to each other, and the winding portion 81 of the biasing member 80 and the locking member 60 are arranged to overlap in a direction perpendicular to the rotation axis C1 of the opening/closing body 40 and the rotation axis C2 of the locking member 60.
  • the winding portion 81 of the biasing member 80 and the locking member 60 are arranged to overlap in a direction perpendicular to the rotation axis C1 of the opening/closing body 40 and the rotation axis C2 of the locking member 60, so that the opening/closing device 10 can have a compact structure while stably applying the biasing force from the second arm portion 85 of the biasing member 80 to the locking member 60.
  • a pair of side walls 23, 25 are provided on the base member 20, a locking member 60 is disposed between the pair of side walls 23, 25, a first pivot support portion (a pair of support holes 27, 27 and a pair of shaft portions 50, 52) is provided on the side walls 23, 25 and the locking member 60, the biasing member 80 is disposed offset toward one of the side walls 25, a protrusion 73 is formed from the abutment portion 65 of the locking member 60 and protrudes toward one of the side walls 25, and the base end of the protrusion 73 in the protruding direction forms a second engaging portion 74 (see Figures 2, 7, 8, etc.).
  • a protrusion 73 is formed from the abutment portion 65 of the locking member 60, protruding toward one side wall portion 25 and having a base end portion in the protruding direction that forms the second engagement portion 74. This makes it easier to engage the second arm portion 85 of the biasing member 80 with the second engagement portion 74 at the base end portion of the protrusion 73 when attaching the locking member 60 to the base member 20, thereby improving the ease of attachment (assembly) of the locking member 60 to the base member 20.
  • a recess 37 is formed on the inner surface of one of the side walls 25 of the base member 20 into which the protrusion of the locking member 60 fits, and the tip 75 of the protrusion 73 in the protruding direction abuts against the inner edge 38 on the first rotation support side of the recess 37 to hold the locking member 60 in place and prevent it from slipping out of the base member 20, with the inner edge 38 and the tip 75 of the protrusion 73 forming a stopper portion (see Figures 2 and 7, etc.).
  • the inner edge 38 on the first rotation support side of the recess 37 on the base member 20 side and the tip 75 of the protrusion 73 of the locking member 60 form a stopper portion, so that while a stopper portion of the locking member 60 is provided, the stopper portion wraps in the thickness direction of the side wall portion 25, making it possible to further compactify the opening and closing device 10.
  • a flange portion 77 is provided from the tip portion 75 of the projection 73 in the protruding direction, protruding so as to be positioned between one side wall portion 25 and the second arm portion 85 of the biasing member 80 (see Figures 2 and 7).
  • the flange portion 77 configured as described above can prevent the second arm portion 85 of the biasing member 80 from contacting one of the side walls 25, so that the biasing force from the second arm portion 85 of the biasing member 80 can be stably applied to the locking member 60.
  • the biasing force from the second arm 85 of the biasing member 80 can be reliably applied only to the second engaging portion 74 of the locking member 60 without being dispersed toward the base member 20, so that the biasing force can be stably applied to the locking member 60.
  • stopper portions are provided at two locations, between the base member 20 and the locking member 60, and between the opening/closing body 40 and the locking member 60, to prevent the locking member 60 from coming off the base member 20.
  • a first stopper portion is provided between the base member 20 and the locking member 60, and is made up of the inner edge portion 38 of the recess 37 of the base member 20 and the tip portion 75 and flange portion 77 of the projection 73 of the locking member 60
  • a second stopper portion is provided between the opening/closing body 40 and the locking member 60, and is made up of the abutment end portion 57a of the recessed groove 57 of the opening/closing body 40 and the engagement portion 70 of the locking member 60, providing two stopper portions.
