Abstract

See full text

A cooling medium accumulation part is integrally formed with a spindle housing and an attaching section between the spindle housing and the attaching section so that at least a width of the cooling medium accumulation part in a direction perpendicular to the spindle is wider than a width of the motor accommodation section in a virtual projection plane obtained by projecting the cooling medium accumulation part in a direction from the spindle housing to the attaching section. A straight oil supply through-holes communicating the cooling medium accumulation part and the cooling passages are formed in a side wall part of the spindle housing.
