Note that the user of the electronic device 1 knows that an excessive force has been applied to the stand 20 due to the touch and sound when the engagement between the engagement convex portion 34c and the engagement concave portion 31c is released. Can do. That is, the release of the engagement between the engagement convex portion 34c and the engagement concave portion 31c also serves to alert the user.

  Such adjustment of the engagement state between the engagement convex portion 34c and the engagement concave portion 31c can be adjusted by both elastic forces. Therefore, instead of the intermediate member 34, an intermediate member 54 as shown in FIGS. 17A to 17F may be employed. Similar to the intermediate member 34, the intermediate member 54 includes a rotating shaft member insertion hole 54a, a torque shaft member mounting hole 54b, and an engaging convex portion 54c1. However, the engaging convex portion 54c1 is formed in the wing-like portion 54c cut out so as to keep only one end in the connected state. If the elastic force is strengthened by bending the wing-like portion 54c toward the engagement recess 31c, the engagement state between the engagement protrusion 54c1 and the engagement recess 31c can be strengthened. On the other hand, if the elastic force is lowered by bending the wing-like portion 54c away from the engagement recess 31c, the engagement state between the engagement projection 54c1 and the engagement recess 31c can be weakened.
