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...

A hole plug for drain which, in a state that the hole plug is mounted to a plate, can ensure good water draining performance even if protrusion towards the outside of a vehicle is reduced and can prevent rainwater from entering the vehicle from the outside. The hole plug includes a protruding portion and a cylindrical portion and is mounted in a state that the cylindrical portion is inserted intoa mounting hole in a vehicle side plate so that rainwater entering the inside of the vehicle and other liquids flow into the cylinder of the cylindrical portion and liquids flowing into the cylinder flow out of the vehicle from a drain hole arranged in a protruding portion. The hole plug is characterized in that the protruding portion includes a flange (1) with a substantially dish shape; the cylindrical portion (2) is disposed on the inner surface side of the flange; the hole plug is provided with the drain hole (14); the cylindrical portion (2) includes an engagement leg (25) provided in a circumference configured to detachably engage the attachment hole (4a); and a shielding wall (24) which is positioned above the drain hole (14), is larger than a horizontal cross-sectional surface of the drain hole, and is provided such that the cylinder inside and the drain hole can communicate with each other.
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...
