Abstract
A base plate includes a bottom wall and a peripheral wall. The peripheral wall extends from the bottom wall to an axially upper side. The bottom wall includes a screw hole recessed from a peripheral edge of a lower end surface of the bottom wall to the axially upper side. The screw hole includes an inclined part and a column body. The inclined part is defined to have an inner diameter that decreases from a lower end toward the axially upper side. The column body extends from an upper end of the inclined part to the axially upper side and is defined with a threaded part. In a cross section including a center line that passes through a center of the column body in an axial direction, the inclined part is inclined at an inclination angle of 25° or more and 35° or less with respect to the center line.
