A method to manufacture electric power steering systems is proposed. First, an electric motor having a drive shaft, a coupling device, and a worm gear having a worm shaft are provided. Then, an adjusting sleeve is provided, and an individual axial position of each adjusting sleeve in its associated opening is determined in order to achieve a specific axial preloading force on the worm shaft. The adjusting sleeve is press-fitted into the axial opening in the determined axial position, and a spring element is installed in the adjusting sleeve so that the spring element is supported on one end axially on the drive shaft and on its other end it is supported axially on the adjusting sleeve, and said spring element acts upon the worm shaft with the preloading force in the axial direction via the adjusting sleeve.

Provided are a winding device and a motor A nozzle that feeds out a coil has: a nozzle hole from which the coil is fed out; an inner-diameter round chamfered part formed on an opening edge of a tip of the nozzle; an outer-diameter round chamfered part formed on the outer peripheral edge of the tip of the nozzle. When the wire diameter of the coil is defined as Φc, the inner diameter of the nozzle hole is defined as Φin, the radius of curvature of the inner-diameter round chamfered part is defined as Rin, and the radius of curvature of the outer-diameter round chamfered part is defined as Rout, they satisfy 1.2Φc≤Φin≤1.4Φc, 0.5Φc≤Rin≤Φc, and 0.25Φc≤Rout≤0.5Φc.

A motor includes: a rotating shaft; a motor portion; a circuit board; a case having a circuit housing recess portion for housing the circuit board; and a cover made of a synthetic resin and sealing the opening portion of the circuit housing recess portion. The cover has an outer circumference rib and an inside rib. The outer circumference rib is located on the outer circumferential side from the opening end surface of the circuit housing recess portion and projects from the outer circumferential edge of the cover toward the front surface side of the cover and the rear surface side of the cover. The inside rib is located inside from the opening end surface and projects at least either on the front surface side of the cover or on the rear surface side of the cover.

Disclosed are a head-up display for a vehicle and a method of controlling the same. The head-up display may include a casing unit, a hinge unit rotatably mounted on the casing unit, a holder unit mounted on the hinge unit, wherein a combiner is positioned on the holder unit, an actuation unit coupled to the hinge unit and configured to rotate the hinge unit, a detection unit configured to detect an initial location of the hinge unit, and a controller configured to receive a detection signal of the detection unit and drive the actuation unit. Accordingly, precise control of the combiner may be possible although only the initial location of the hinge unit is detected.

An electronic device is provided. The electronic device includes a function module, a body, and a motor assembly. The body includes an accommodation space for accommodating the function module. The motor assembly includes a drive motor, a gear, a rotation output shaft, a displacement mechanism, and a latch. The drive motor includes a shaft. The gear is fixedly attached to the shaft. The rotation output shaft includes a gear teeth portion. The gear teeth portion is coupled to the gear. The rotation output shaft is connected to the function module and is configured to drive the function module to rotate. The displacement mechanism synchronizes with the shaft and is separated from the rotation output shaft. The displacement mechanism includes a linear motion component. The latch is connected to the linear motion component, and is configured to engage the function module.

A method for attaching a plastic barrel configured to guide an output shaft of a mechanical device to a housing for the mechanical device is disclosed. The housing includes a chimney delimited by an upper edge and a base, the chimney being arranged to partially surround the output shaft, the plastic barrel having a lateral protuberance. The method involves at least the following steps: inserting a first end of the plastic barrel into the chimney of the housing until the lateral protuberance axially abuts against the upper edge of the chimney, and at least partially deforming the first end of the plastic barrel in order to form an axial counter-abutment.

The rotating device includes a housing, a motor, a gear transmitting rotation of the motor to an outside, a sensor, a connection terminal electrically connected to the outside, and a wiring board. The wiring board electrically connects the motor, the sensor, and the connection terminal. The wiring board is formed of a film having a flexiblity. A rotation speed or a rotation angle of the gear is detectable by the sensor. An electronic component controlling the motor is mounted at the wiring board. A part of the wiring board includes a bent part or a curved part and surrounds a part of the electronic component.
