The holes provided in the sliding blocks 302R and 302L through which the guide bars 304R and 304L penetrate are not threaded, and the guide bars 304R and 304L are not threaded either.

The lower ends of the male screw bolts 303R and 303L are connected to the motor shafts 306R and 306L of the motors 305R and 305L, respectively.

The lower ends of the guide bars 304R and 304L are fixed to the fixing blocks 307R and 307L, respectively.

The motors 305R and 305L and the fixed blocks 307R and 307L are fixed to the right side surface portion 314R and the left side surface portion 314L of the housing portion 101, respectively.

In the linear actuator mechanism units 301R and 301L having the above configuration, when the motor shafts 306R and 306L of the motors 305R and 305L rotate counterclockwise, respectively, the male screw bolts 303R and 303L also rotate counterclockwise. As a result, the male screw bolts 303R and 303L mesh with the female screws in the sliding blocks 302R and 302L, respectively, so that the sliding blocks 302R and 302L slide downward.

Conversely, when the motor shafts 306R and 306L of the motors 305R and 305L rotate clockwise, respectively, the male screw bolts 303R and 303L also rotate clockwise. As a result, the male screw bolts 303R and 303L mesh with the female screws in the sliding blocks 302R and 302L, respectively, so that the sliding blocks 302R and 302L slide upward.

In the sliding blocks 302R and 302L, the housing portion side holding members 308R and 308L, which are the constituent members of the head-mounted display holding portions 103R and 103L, respectively, are firmly bolted to the sliding blocks 302R and 302L.
