Abstract

In electric equipment for railway vehicle, a hanging structure which is capable of accommodating a limitation in mounting position on the vehicle side without increasing the mass or the number of components and changing the arrangement of electric equipment in a box is provided. A hanging part having an integrated structure in which a hanging part (9A) having a shape accommodating limitations in mounting position on the vehicle side in the direction of crosstie and in the vertical direction is joined to a metallic plate (9C) is joined to a ceiling plate (2a) and a side plate (2b) of a box member (2) at a position corresponding to the limitation in mounting position in the direction of travel of the vehicle side. The electric equipment for railway vehicle is hung from a beam under a floor of the vehicle via a bolt hole provided on an upper portion of the hanging part.

Description

technical field [0001] The present invention relates to electrical products for railway vehicles. Background technique [0002] Figure 5 It is an explanatory diagram showing a structure in which an electric product to which the present invention is applied is equipped on a body of a railway vehicle. [0003] A curtain rail 30 parallel to the traveling direction K of the vehicle is fixed to the lower surface of the floor of the vehicle body 20 , and the electric product 1 is mounted on the curtain rail 30 . [0004] Figure 6 The state where the electric product 1 is attached to the curtain rail 32 fixed parallel to the sleeper direction L of the vehicle body 20 is shown. Arrow M indicates the up-down direction of the vehicle body. [0005] Figure 7 express Figure 5 The detail of the main part of 2 shows the state in which the electric product 1 is hung on the curtain rail 30 via the hanging tool 40 with respect to the traveling direction. [0006] Figure 8 (a) is a...
