The invention relates to a lighting device, which includes a light source, a pattern disc provided with a plurality of pattern sheets, a rotating shaft and a drive mechanism. The rotating shaft passes through the axial center of the pattern disc and is driven to rotate by the drive mechanism to rotate the pattern disc. The pattern sheets are then rotated in turn to a light path of the light emitted by the light source. The lighting device further includes a positioning unit for pattern disc including a Hall plate, a fixing bracket for the Hall plate and a magnet. The Hall plate is mounted on the fixing bracket for the Hall plate, and the magnet is mounted on the pattern disc. The pattern disc is rotated to bring the magnet close to the Hall plate to generate magnetic induction. According to the present lighting device using the Hall induction principle and the Hall plate, the reset and positioning of the pattern disc of the lighting device is effectively realized with less errors, and the precision of the reset positioning of the pattern disc and the artistic ambience effect of the light fixture are improved. Therefore, the lighting device is applicable to the reset and positioning of pattern discs of various kinds of light fixtures.

A step motor that drives a rotary body to rotate includes: an output shaft that outputs a rotational driving force to the rotary body, the output shaft having an insertion hole in which the rotary body is arranged so as to be integrally rotatable on an inner circumference side of a top portion of a tip end of the output shaft; a radial bearing radially supporting the output shaft from an outer circumference side; and a cover protruding from the radial bearing radially inward. The cover opposing the top portion through an axial gap at an outer circumference side of the insertion hole. The output shaft has an inner tapered portion which decreases in diameter as approaching the insertion hole radially inward from the top portion. The cover opposes the top portion through the axial gap at an outer circumference side of the inner tapered portion.

A head-mounted display device and an external adjustment module are provided. The head-mounted display device includes a body and the external adjustment module. The body has a first lens and a second lens corresponding to both eyes, and also has a driven mechanism. The first lens and the second lens are respectively coupled to the driven mechanism. The external adjustment module includes a driving element and a transmission element. The transmission element is assembled to the driving element and used for coupling to the driven mechanism. The driving element is used for driving the driven mechanism through the transmission element to adjust a distance between the first lens and the second lens.

In the case of this motor device, tip parts (230) of first protrusion sections (23), which hold a stator core (60) from inside of a first case (21) in the direction of a rotational center axis line (LO) in conjunction with a second case (22), are tapered toward the stator core (60). Also, tip parts (240) of second protrusion sections (24), which hold the stator core (60) from inside of the second case (22) in the direction of the rotational center axis line (LO) in conjunction with the first case (21), are tapered toward the stator core (60). Thus, when the protruding lengths of the first protrusion sections (23) and the second protrusion sections (24) are set somewhat long in advance, the first protrusion sections (23) and the second protrusion sections (24) hold the stator core (60) in a state in which the tip parts (230, 240) are crushed.
