As disclosed in Japanese Patent No. 82113, the exterior panel is attached to the base by fixing bolts at a plurality of points on the exterior panel. In addition, 59-82
In Japanese Patent No. 133, the four corners of the exterior panel are fixed to the base.

[Problems to be solved by the invention]

However, in the case of the above-mentioned conventional technique, it is time-consuming and requires a tool such as a wrench. Moreover, it requires skill to stabilize the tightening force and ensure the fixing. Since it was fixed to the groundwork, the workability was poor.

An object of the present invention is to provide a mounting structure for an exterior panel that allows the exterior panel to be attached to a base with good workability.

[Means for solving problems]

The characteristic structure of the mounting structure of the exterior panel according to the present invention is that a plurality of mounting portions to the base are arranged at intervals in the width direction of the exterior panel at each of a plurality of vertically spaced intervals on the back surface of the exterior panel. Attached to the state of
Attaching a locking piece that engages each mounting portion and fixes the exterior panel to the base to each of the locations corresponding to each mounting portion, and attaches all of the mounting portions to the corresponding locking piece in the out-of-plane direction. It is configured to engage to fix the position of the exterior panel in the out-of-plane direction with respect to the base, and of the mounting portions, a pair of mounting portions attached to any one of a plurality of upper and lower locations is used. It is configured to be placed and supported on the locking piece in a state of being engaged with the locking piece in the out-of-plane direction.

[Action]

By engaging the mounting portion on the exterior panel side with the locking piece on the base side, the exterior panel is load-supported on the base and is fixed in the out-of-plane direction, so when mounting the exterior panel on the base, , It suffices to engage the mounting part with the locking piece. Compared with the case of tightening bolts,
No labor or skill is required for installation.

In addition, for example, when the entire mounting portion is placed on and supported by the locking piece and the exterior panel is load-supported on the base, there is an error in the mounting position of the locking piece on the base, or If there is an error in the position of attachment to the exterior panel, not all of the attachment parts are evenly placed and supported on the locking pieces, and the attachment of the exterior panel to the base becomes loose. Such rattling of the exterior panel causes mounting failure, and in particular, the exterior panel is provided with a sealing material around its periphery that closes the space between the adjacent exterior panel or the base material. If the seal is also intended to be installed at the same time, the contact of the sealing material with the adjacent exterior panel or the base is poor, and rain cannot be surely applied.

On the other hand, according to the present invention, only the pair of mounting portions are provided while the outer panel is securely fixed to the fixing portion in the out-of-plane direction by engaging all of the mounting portions with the locking pieces in the out-of-plane direction. Since the outer panel is load-supported on the base by placing it on the locking piece, that is, the load is supported at two points, the mounting position of the mounting part on the outer panel and the mounting position of the locking piece on the base are determined. Even if there is some error, the exterior panel can be attached to the base without rattling.

[Effect of device]

As a result, according to the present invention, it is possible to attach the mounting portion to the exterior panel and the locking piece to the base with good workability.
As a whole, it is possible to attach the exterior panel to the base with good workability and without rattling. Especially, by attaching a sealing material to the exterior panel and attaching the exterior panel to the base, it is possible to attach the exterior panel to the adjacent exterior panel or the base. Seal between,
In other words, the sealing material can be surely brought into contact with the adjacent exterior panel or the base when the rain wrapping is performed at the same time, and a useful exterior panel mounting structure can be provided.
