Cooling component for automobile and manufacturing method of cooling component for automobile

A method for manufacturing a cooling component for an automobile,

• wherein, in a pump which includes:
• a case that has a case opening at an end portion in a first direction along a central axis, accommodates components of the pump on an inward side in a second direction perpendicular to the central axis, and has a case weld portion along a peripheral edge of the case opening;
• and
• a cover that is disposed side by side with a side of the case in the first direction, has a cover opening facing the case opening, and has a cover weld portion along a peripheral edge of the cover opening,
• when one of the case weld portion and the cover weld portion is referred to as a first weld portion, and the other thereof is referred to as a second weld portion,
• an inclined surface, which is inclined from an inward side to an outward side in the second direction away from the second weld portion, is formed at a tip end of the first weld portion in the first direction,
• a first flat surface intersecting with the first direction is formed on an inward side of the inclined surface in the second direction at the tip end of the first weld portion in the first direction,
• a second flat surface intersecting with the first direction is formed at a tip end of the second weld portion in the first direction, and the first weld portion and the second weld portion are joined to each other by welding, and
• the cooling component for an automobile further comprising:
• an inner standing wall that is disposed away from the first weld portion and the second weld portion to an inward side in the second direction;
• and
• an outer standing wall that is disposed away from the first weld portion and the second weld portion to an outward side in the second direction.
