And a holder that is continuous with the other flexible portion and that includes an engaging projection that can be removably engaged with the engaging recess of the electronic device housing.

A hole for inserting a belt can be formed in the back plate of the holder.

[0010]

Therefore, according to the present invention, the engaging projection of the holder is released by the housing of the electronic device by utilizing the elastic deformation of the flexible portion, and the engaging groove and the engaging projection of both are engaged, When the engaging projection is disengaged from the end of the electronic device housing, the engaging projection is engaged with the engaging recess of the electronic device housing by the restoring force of the flexible portion, and the electronic device housing is attached to the stopper of the holder. The surface on the side opposite to the engaging concave portion can be engaged and held in a fixed state. In addition, the stopper of the holder is pressed to elastically deform the flexible portion to disengage the stopper from the engaging surface of the electronic device housing, and then the engaging projection of the holder is electronically deformed by utilizing the elastic deformation of the flexible portion. Disengage from the engagement recess of the device housing,
After that, the electronic device housing can be removed from the holder by disengaging the engaging groove and the engaging protrusion of both.
Then, the three directions of the electronic device housing and the holder are engaged by the engagement groove and the engagement projection, the engagement recess and the engagement projection, and the remaining one direction is engaged by the stopper, so by any chance, Even if the stopper is disengaged from the engaging surface of the electronic device housing, the three-direction engaging portions can be caused to bite by the pressing force of the stopper against the electronic device housing due to the repulsive elasticity of the flexible portion. Moreover, since the front surface of the electronic device housing is not rubbed with the holder, it is possible to prevent the front surface from being scratched.
