The lower surface of the groove 6a forming the guide path is the same as the groove.
6a is inclined so that the open rear end is slightly lower, and the upper and lower portions of the open rear end are expanded rearward, so that the convex piece 4c is smoothly inserted into the concave groove 6a. Will be able to lead to.

The locking claw 10 is provided on the lower panel 6.
A plurality of protrusions are provided on the left and right sides of the back surface of the front end so as to face the periphery of the flange 4a. This is the flange 4a
By locking the plurality of locking claws 10 using the peripheral edge of the lower panel 6, the lower panel 6 is joined to the upper panel 4 in a state where the front end of the lower panel 6 is positioned in a balanced manner on the right and left.

Furthermore, the locking claw 10 is projected from the back surface of the front end of the lower panel 6. This is because the locking claw 10 is pressed against the peripheral edge of the flange 4 a while being pressed with fingers. This is for the purpose of accurately sensing the feeling of being locked to the vehicle.

As described above with reference to FIGS. 1 and 2, the air conditioner according to the present invention has a front surface of the base 2 mounted on a wall surface of the room to be air-conditioned via a mounting plate (not shown).
