Abstract: A rotation detection device includes a housing that accommodates a rotating body, a detected part that rotates integrally with the rotating body, a detection part that faces the detected part in an axial direction with an axial gap interposed therebetween, an installation member on which the detection part is installed, a female screw portion that is provided in one of the housing and the installation member, and a male screw portion that is provided in the other of the housing and the installation member and screwed into the female screw portion.

Abstract: Provided is a bending meshing type gear device including a wave generator, an external gear flexibly deformed by the wave generator, and an internal gear meshing with the external gear. The internal gear includes an internal tooth ring portion including an internal tooth formed on an inner periphery, an external connection portion connected to an external member, an easily deformable portion provided between the internal tooth ring portion and the external connection portion, and configured to be more easily deformable than the internal tooth ring portion, and a distortion measurer provided in the easily deformable portion.

Abstract: Provided is a gear motor including a motor, a speed reducer, a first detector disposition section in which a first rotation detector that detects rotation of a rotor shaft is disposed, a second detector disposition section in which a second rotation detector that detects rotation of an output member of the speed reducer is disposed, and a third detector disposition section in which a torque detector is disposed, in which the gear motor is operable when the first rotation detector is disposed in the first detector disposition section, the second rotation detector is disposed in the second detector disposition section, and the torque detector is disposed in the third detector disposition section, and is operable even when a portion thereof is disposed.

Abstract: An actuator controlled by a driver, includes an actuator-side connector that is detachably connected to a driver-side connector provided in the driver, in which the actuator is able to be electrically connected to the driver, by connecting the actuator-side connector and the driver-side connector to each other.

Abstract: A hollow-shaft arrangement for a motor vehicle includes an inner hollow shaft and an outer hollow shaft. An inner shaft shoulder of the outer hollow shaft is arranged behind the inner toothing in an axial direction as viewed from the inflow end of the inner hollow shaft, the inner diameter (D1) of which shaft shoulder is smaller than a root-circle diameter (D2) of the inner toothing, so that, when the hollow shafts rotate, the fluid exiting from the outflow end of the inner hollow shaft at least partially is backed up by the shaft shoulder in a tooth root region of the inner toothing and flows back in the direction of the inflow end of the inner hollow shaft within the splice toothing.
