  A swingable space that does not hinder the swing of the swing support side end 24 is formed on the lower surface side of the end portion of the case body in the shaft support portion. A locking portion 65 that contacts the stepped portion 64 is formed on the back side of the end portion of the case upper member 8. When the projecting operation portion 42 is pulled toward the support member 13 side of the opening 86 by a finger operation, a locus having a larger radius than the tip locus circle R2 of the swing support side end portion 24 that rotates about the rotation shaft 26 as a rotation center. The curved portion 47 of the sliding member 39 can be retracted toward the shaft support member 13 so as to form a swingable space of the circle R1. When the force that pulls the protrusion operating portion 42 toward the shaft support member 13 side of the opening 86 is removed, the downward protrusion 46 is slidable to the right end side under the biasing force of the spring 43.

  When the insertion shafts 6 and 7 are rotated from the hanging position in FIG. 3 to the laterally open position, the tip surfaces of the swing support side end portions 23 and 24 close to the stepped portions 63 and 64 are projected operation portions 41 and 42. While moving to the curved surface of the curved portion 47, it moves to the laterally open position (lock position), and then the contact surface of the stepped portions 63 and 64 contacts the lower surface of the downward projecting portion 46 of the projecting operation portions 41 and 42. It is possible to shift to a locked state (see FIG. 8 described later). A contact mechanism between the projecting operation portions 41 and 42 and the swing support side end portions 23 and 24 functions as a kind of cam mechanism. That is, when the insertion shafts 6 and 7 are in the suspended state (unlocked state), the projecting operation portions 41 and 42 are biased outward from the shaft support member 13 by receiving the biasing force of the spring 43. The projecting operation portions 41 and 42 are moved inward by the action of the inward movement from the shaft support member 13 due to the contact on the curved surface of the bending portion 47 during the pivoting operation of the shafted bodies 6 and 7. At the locking position, the inward action is lost and the movement again outwards, so that it is possible to shift to a locked state in which the contact surfaces of the stepped portions 63 and 64 are in contact with the lower surface of the downward projecting portion 46.
