An indoor unit includes an indoor side switch device which is brought into a closed state at a startup time when operation starts from a standby state. In the optical scanning device, a beam incident on a scanning area of an object’s surface to be scanned and a beam incident on a synchronization signal detector are emitted by a light source but deflected from different deflecting surfaces of a beam deflector. A fiber retention subassembly crimps to one of the coaxial tubes, and an adhesive fills the fiber retention subassembly, thereby fixing the fibers therein and isolating tension from the ends of the fibers that extend from the fiber retention subassembly. A degree of offer of the drive support information is limited when the own vehicle is present within an area where an error in the positional information meets or exceeds a predetermined level. The translucent body panels can be sufficiently opaque to mask the components positioned behind the body panel when the motorcycle is viewed from a distance, but yet allow visual inspection of those components when viewed from a position adjacent the motorcycle.
