 Many automobiles are equipped with so-called car audio, and their speakers are usually attached to, for example, the rear panel behind the rear seats or the lining parts of the doors on both sides of the front seats. In this case, it is required in the automobile industry to measure the ease of mounting in terms of productivity.

[0003]

[Problems to be solved by the device]

 However, when mounting the speaker to the door, unlike mounting to other parts, a shock due to a strong moment of inertia that occurs when the door is opened and closed acts on the mounting part, so that a relatively heavy object such as a speaker may be installed on the door. There was a problem that the installation work was complicated and the productivity was poor, because we had to rely on solid fixation with old-fashioned screws so that it would not come off due to the shock of opening and closing.

The present invention has been proposed in view of the above points, and an object thereof is to attach a speaker to a door and cause a speaker to rattle or come off due to a shock caused by opening or closing the door. It is to provide a mounting structure for an in-vehicle door speaker that is easy to install and reliable.
