Embodiment Construction

[0043] Embodiments of the present invention and modifications thereof will be described below with reference to the drawings. In this description, the structure of the plug of the embodiment, its main operation, and Modifications 1 and 2 will be described in detail in order.

[0044] (structure) Figure 1(a) to Figure 7(b) Among them, the drain plug 3 is composed of a resin injection molded body, has a flange 1 as a protruding portion, and a cylindrical portion 2 protruding from the inner side of the flange 1, and is attached so that the cylindrical portion 2 is inserted into the vehicle body. The state of the mounting hole 4 a of the side panel 4 allows liquid such as rainwater entering the vehicle to flow into the cylinder 20 of the cylindrical portion 2 and flow out of the vehicle through the drain hole 14 provided in the flange 1 . The main creative point is that the flange 1 is roughly disc-shaped, has a vertical hole-shaped drainage hole 14 and a cylindrical part 2 prot...

Abstract

Disclosed is a plug for drainage that ensures good drainage performance and prevents rainwater from entering the vehicle interior from the outside even if the amount of protrusion toward the vehicle exterior is reduced in the installed state of the panel. The drain plug has a protruding part and a cylindrical part, and is installed so that the cylindrical part is inserted into the mounting hole of the side panel of the vehicle body, so that liquid such as rainwater entering the vehicle can flow into the cylinder of the cylindrical part , and make the liquid flowing into the tube flow out of the vehicle from the drain hole provided in the protruding part. It is characterized in that the protruding part is composed of a substantially disc-shaped flange (1), and a cylindrical part (2), and has a drainage hole (14), and the cylindrical part (2) has: an engaging foot part (25), which is provided around the cylindrical part, and is engaged or disengaged from the mounting hole (4a); the shielding wall (24), which is set in the following state: it is located directly above the drain hole (14), is larger than the horizontal section of the drain hole, and communicates the inside of the cylinder with the drain hole.

Description

technical field [0001] The present invention relates to a method that is installed on the side panels of automobiles and the like so as to allow liquids such as rainwater to enter the interior of the vehicle (the liquids such as rainwater herein refer to liquids accumulated in, for example, storage tanks of car doors or luggage compartments). etc. It is used in a broad sense. The same applies below.) A hole plug for drainage that flows out of the vehicle. Background technique [0002] Figure 10(a) ~ Figure 10(b) This is the plug disclosed in Patent Document 1. This plug structure is composed of a single resin molded product, has a cylindrical portion 1 and a cover portion 5 as a protruding portion, and is attached in a state where the cylindrical portion 1 is inserted into the mounting hole 99 of the vehicle body side panel 9, Liquid such as rainwater entering the vehicle is made to flow into the hollow portion 11 in the cylindrical portion 1 , and the liquid in the pipe t...
