Abstract: To radiate light with uniform color and illuminance in a longitudinal direction, this vehicle light guide is rod-shaped and is disposed at a front portion of a vehicle. The vehicle light guide includes a base portion having a curved portion curved rearward from a front toward a side of the vehicle and guiding light from a light source so as to be emitted from an emission face at a front side of the vehicle, a plurality of prism portions arrayed in a longitudinal direction along a back face of the base portion and that reflect light forward, and a diffusing portion positioned in at least the curved portion in the longitudinal direction of the base portion and provided in a strip form on a bottom face side of the prism portions, and that diffuses light.

Abstract: A fixed-side support arm (17) of a torsion coil spring (10) is provided with a locking portion (17a) and a pressing portion (17c). The locking portion (17a) is housed in a recessed spring housing portion (22) provided in a lever (9), and an engaging portion (22a) abuts against the locking portion (17a) to lock a biasing force of the spring. A pressing force (F) is applied to the pressing portion (17c) to remove the locking portion (17a) from the spring housing portion (22), thereby releasing the locking by the engaging portion (22a).

Abstract: A back face of each inner link plate of the chain is curved convexly. Heights from a pitch line connecting centers of pin holes of inner and guide link plates to the convex apex portion of the inner link plate and to an apex portion of the guide link plate are equalized. The convex apex portions are brought into contact with a guide face of the chain guide per every pitch and the ear apex portions are brought into contact with the chain guide per every pitch while being shifted by a half pitch from the convex apex portions.
