Abstract: A reflector comprises a body having a reflecting member constituting the front surface and a base member mounted on the reflecting member and a plurality of reflex reflector structures provided along the front surface of the body, while the front surface has a curved shape arched in a longitudinal section of the body and the optical axes of the plurality of reflex reflector structures are directionally constant along the overall longitudinal direction of the body.

Abstract: A headlamp for a bicycle includes an LED element, a power supply device supplying electric power to the LED element, a vibration sensor detecting vibration, a luminance detector detecting ambient illuminance, and a switching device providing ON-OFF control of electrical connection between the LED element and the power supply device in response to a result detected by the vibration sensor and a result detected by the illuminance detector. The vibration sensor has a helical spring and a central metal conductive wire passing through the helical spring, and the helical spring and the conductive wire are disposed to extend in a direction obliquely intersecting with a horizontal direction and a vertical direction when the headlamp is attached.

Abstract: A delineator easily recognized by the driver even when attached at a moderate curve of a road includes colorless transparent reflectors attached inclined by a prescribed angle with respect to an aluminum base and amber transparent reflectors attached inclined in the opposite direction. Each reflector has a reflex reflecting element, an optical axis of which is inclined in the same direction as the corresponding reflector. Thus light beams entering in a direction parallel to the surface on which the delineator is attached can also be reflected.
