Abstract: A water-cooled motor includes: an annular stator having a central axis; and an annular housing surrounding the stator around the central axis and provided with a cooling channel within the housing, the housing includes: an annular non-magnetic metal pipe; and a casting member cast to envelop the metal pipe around the central axis, and the metal pipe is located inward of the cooling channel and located outward of an outer surface of the stator, in a radial direction of the stator.

Abstract: A transaxle for an electric vehicle includes a motor, an inverter chamber, an oil chamber, and a cooling liquid chamber. The inverter chamber accommodates an electronic component configured to control the motor. The oil chamber is configured to store an oil that serves as a refrigerant. A cooling liquid that cools the electronic component flows through the cooling liquid chamber. The inverter chamber includes a wall also serving as a wall of the cooling liquid chamber. The oil chamber includes a wall also serving as a wall of the cooling liquid chamber.

Abstract: A cuff support attached to an axial end surface of a stator core including an annular yoke, a plurality of teeth, and a plurality of slots formed between the teeth includes: an annular plate making contact with the yoke; a plurality of ribs projecting toward an inner peripheral side of the annular plate so as to correspond to the teeth; and a plurality of spaces formed between the ribs so as to correspond to the slots. The cuff support is made of an elastic member. The ribs are being apart from the axial end surface of the stator core from roots of the ribs toward tip ends of the ribs. When a coil is wound around the teeth and the ribs so as to pass through the slots and the spaces, the ribs are brought into pressure contact with the coil due to an elastic force.

Abstract: An image forming apparatus prevents link members for monochrome and for color from coming off while suppressing an increase in rotatory torque and a deficiency of clutch capacity for transmitting a driving force to a cam shaft. Coming-off protection sections for preventing the coming off of a second link member which is the link member for color is provided in a cam section for monochrome. In other words, it is not necessary to provide a coming-off protection section in a second cam section which is a cam section for color requiring a large rotatory torque. This eliminates the need for a coming-off protection section of the cam section for color to act on the link member for color when a cam is turned by a driving source.

Abstract: Preventing link members for monochrome and for color from coming off while suppressing the occurrence of an increase of a rotatory torque and a deficiency of clutch capacity for transmitting a driving force to a cam shaft is sought. Coming-off protection sections (second and third coming-off protection sections (236), (237)) for preventing the coming off of a second link member 22 which is the link member for color is provided in a cam section for monochrome (first cam section 233). In other words, it is not necessary to provide a coming-off protection section in a second cam section 234 which is a cam section for color requiring a large rotatory torque. This eliminates the need for a coming-off protection section of the cam section for color to act on the link member for color when a cam 23 is turned by a driving source, thereby making it possible to suppress the occurrence of the increase of the rotatory torque and the deficiency of clutch capacity for transmitting the driving force to the cam shaft.

Abstract: A belt driving device includes an endless belt, a tension roller, a shaft member, deviation transfer members, and biasing members. The deviation transfer members are fitted over the shaft member in such a manner as to adjoin respective of opposite ends of the tension roller in an axial direction of the tension roller. Of the deviation transfer members, at least that deviation transfer member which is located on a downstream side in a deviation direction along the axial direction is movable together with the endless belt along the shaft member. Each of the biasing members has an acting end pivotally supported on an associated one of the deviation transfer members and a base end pivotally supported on an associated one of apparatus frames at a predetermined position.

Abstract: A printer with a printhead pressure adjusting mechanism including a thermal head, a platen drum, an adjusting mechanism, a detection device [e.g., switch(es)] and a control unit. The thermal head transfers ink of an ink ribbon onto recording paper by heat generation. The platen drum sandwiches the ink ribbon and the recording paper under pressure together with the thermal head. The adjusting mechanism adjusts the pressure being applied to the thermal head when pressing the thermal head. The detection device detects the size of the recording paper. The control unit controls the adjusting mechanism in order to adjust the pressure being applied to the thermal head in accordance with the detected size of the recording paper.
