Embodiment

[0046] Next, embodiments of the present invention will be described based on the drawings.

[0047] figure 1 as well as figure 2 The gasket 1 according to the embodiment of the present invention is shown. The gasket 1 according to this embodiment is installed in a mounting groove 63 provided on one of the two opposing parts (for example, a casing of a power control unit such as a converter) 61, and is connected to the other part ( For example, a case cover (case cover) 62 of a power control unit such as an inverter is in close contact with, and the gasket 1 is constituted as follows.

[0048] That is, the liner 1 is shaped by a prescribed rubber-like elastic body, such as figure 1 As shown in (A), its planar shape is a substantially rectangular frame shape.

[0049]Additionally, if figure 2 As shown, the gasket 1 has a gasket body portion (pad base portion) 2. As for the gasket body portion 2, in the installed state, one end (lower end) 2a in the height direction (up ...

Abstract

Provided is a gasket configured so that air is unlikely to be trapped between the gasket and the groove bottom surface during the mounting of the gasket in a mounting groove, and therefore push-in resistance during the mounting of the gasket does not increase and the gasket is not lifted from the mounting groove by spring back due to the trapped air. A gasket is adapted to be mounted in a mounting groove in one of two members facing each other and to be in close contact with the other member. A seal protrusion which comes into contact with a side surface of the mounting groove is provided on a side surface of the gasket so as to extend along the entire circumference of the gasket. A recess which serves as an air vent during the mounting of the gasket in the mounting groove is provided in a circumferential portion of a side surface of the gasket. The recess is formed in a shape having a predetermined curvature in the longitudinal direction of the gasket.

Description

technical field [0001] The invention relates to a gasket, which is a kind of sealing device related to sealing technology. The gasket of the present invention is used, for example, as a gasket for a power control unit such as a converter. Background technique [0002] For example, the housings of power control units such as inverters used in electric vehicles are often formed by stamping or casting (aluminum casting). Large, which will hinder the use of gasket sealing. [0003] Therefore, in recent years, proposals have a liner 51 such as Figure 4 As shown, the gasket 51 is installed in the installation groove 63 provided on one of the two parts 61, 62 facing each other, and is in close contact with the other part 62, and is in contact with the groove side 63b of the installation groove 63 The sealing protrusion 52 is provided on the side surface of the gasket 51 over the entire circumference of the gasket 51 (Patent Document 1).
