Vehicle control device for electric rolling stock

摘要

A draining member protrudes from both openings of a through-hole in a vehicle control device. It has a pair of spaced elastic members extending from a connection. The connection has a width smaller than a width of the through-hole. The width between the elastic members varies from the connection toward their ends, reaching a narrow portion smaller than the width of the through-hole via an increased width portion greater than the width of the through-hole. A leg portion beyond the narrow portion has a width greater than the width of the through-hole. A minimum distance between a location where the width between the increased width portion and the narrow portion matches the width of the through-hole, and another location where the width of the leg portion is equal to or greater than the width of the through-hole, is equal to or greater than a thickness of the housing.

主权项

1. A vehicle control device for electric rolling stock, the vehicle control device comprising:
a housing with a through-hole formed in a bottom surface thereof; and a draining member that is inserted into the through-hole and is held in a state protruding from both openings of the through-hole, wherein: the draining member is formed of a pair of elastic members extending separately from a connecting location, mutually connected, and facing face each other across a space, the connecting location has a width smaller than a width of the through-hole, a width between the pair of elastic members facing each other is varied from the connecting location toward ends of the elastic members, the draining member includes: a narrow portion having a width that is smaller than the width of the through-hole; an increased width portion having a width that is greater than the width of the through-hole; and a leg portion at a distance from the narrow portion and having a maximum width that is greater than the width of the through-hole; a minimum distance between a first location at which the width of the pair of elastic member facing each other between the increased width portion and the narrow portion matches the width of the through-hole, and a second location at which the width of the pair of elastic members of the leg portion facing each other is equal to or greater than the width of the through-hole, is equal to or greater than a threshold value that is greater than a thickness of the housing, and when a pressure equal to or greater than a threshold value is applied in a direction for closing the increased width portion, the width of the increased width portion becomes smaller than the width of the through-hole.
