の視線が行く旋回軌跡Ａ上は多少暗くなりがちで
あつた。(Problem to be solved by the invention) In a motorcycle, a turning trajectory A as shown in Fig.
When cornering, the vehicle body 1 is tilted almost without turning the steering wheel. Therefore, if the irradiation range of the headlight 2 is D 1 (d a + d b ), the range of visibility in the direction of travel due to the irradiation of the headlight 2 is d b
You will only get that part. Therefore, the turning trajectory A along which the driver's line of sight follows tends to be somewhat dark.

When the vehicle body 1 is tilted by θ 1 with respect to DL 1 and the ground is at the position of GL 2 on the drawing with respect to the vehicle body 1, the headlight 2 will also be tilted by the same angle, so the upper limit of the light distribution on the turning trajectory A will be the HL 1 line. As the visibility range decreases, the turning trajectory A
It was a good win as it got a little dark above.

れる。(Function) When cornering, the headlight rotates in the turning direction from optical axis to optical axis as shown in Figure 5 by the optical axis adjustment angle θ 2 corresponding to the turning radius obtained by the calculation means, and the irradiation range is D. It becomes 2 . Therefore,
The irradiation range d a that was wasted in the past is eliminated, and the irradiation range on the turning trajectory A indicated by diagonal lines increases by that amount, making the field of vision brighter. Further, during cornering, the headlight 2 rotates in the direction opposite to the direction of inclination by the vehicle body inclination angle θ 1 obtained by the vehicle body inclination detection means. Therefore, the upper limit of the light distribution on the turning trajectory A becomes the HL 2 line as shown in Figure 6, and the visibility is further improved only in the shaded area.

界が増大する。 In FIG. 4, the calculating means 9 includes the vehicle speed detector 1
Using the vehicle speed signal of 0 and gyroscope 7 and the vehicle body inclination signal θ 1 , the following R = 2 / tan θ 1 (1 + k) where k is a constant determined by the total vehicle weight, the height of the center of gravity, the weight equivalent to the inertia of the front and rear wheels, etc. The turning radius R is calculated from the turning radius R, and the corresponding optical axis adjustment angle θ 2 of the headlight 2 is calculated from the turning radius R. The output of the calculation means 8 is applied to the servo motor 5 via the drive circuit 11, and the servo motor 5 directs the headlight 2 to the optical axis obtained by the calculation means 9 with the vertical support shaft 6 as the center. Since it is rotated by the adjustment angle θ 2 in the turning direction, the shaded area in FIG. 5 also becomes the irradiation range, and the field of view on the turning trajectory increases.

の視界が増大する。 Further, the output of the gyro meter 7 is applied to the servo motor 3 via the drive circuit 12, and the servo motor 3 is connected to the horizontal support shaft 4 of the headlight 2.
Since the vehicle rotates in the direction opposite to the vehicle body tilt direction by the same angle as the vehicle body tilt angle θ 1 obtained with the gyroscope 7, the upper limit of the light distribution in the traveling direction is upward as shown in the HL 2 line in Figure 6. The slanted portion also becomes an irradiation range, increasing visibility in the direction of travel.
