A surface pressure measuring device includes an abutting plate, a lift, a probe, a piezo actuator and a controller. A pinhole is formed in the abutting plate at an abutting surface that abuts a target. The lift causes the target to abut the abutting surface such that the target is compressed to a predetermined thickness. The probe is inserted through the pinhole to be movable in an axial direction of the pinhole. The piezo actuator holds a state in which a tip surface is flush with the abutting surface as the probe resists a repulsive force received from the target while the lift causes the target to abut the abutting surface. The controller calculates a local surface pressure of the target from a load applied to the probe and an area of the tip surface of the probe.

Heat discharging property of the stator coil end is improved effectively in a rotating electric machine. A motor as the rotating electric machine includes a stator and a rotor. The stator includes a stator core and resin mold coil ends provided on both axial ends thereof. Column-shaped projections projecting in the axial direction are provided on axial side surfaces of resin mold coil ends at a plurality of positions. Cooling oil supplied from above the resin mold coil ends effectively cools the resin mold coil ends.
