Abstract:
A ball screw device includes a screw shaft, a nut, and a housing that has a bottomed cylindrical shape and to which the nut is attached. The ball screw device converts rotational motion of the screw shaft into linear motion of the housing. The ball screw device is switched between a normal use state and a supply state. In the normal use state, along with the linear motion, a bottom portion of the housing reciprocates between a first position spaced apart from an end of the screw shaft and a second position closer to the end. In the supply state, along with the linear motion, the bottom portion of the housing is located in a third position even closer to the end of the screw shaft, such that grease present in the nut and the bottom portion of the housing is introduced to a radially inner side of the nut.

Claim (Index 2):
The ball screw device according to  claim 1 , wherein the supply state is less frequently established than the normal use state.
