    • A focus detecting apparatus is provided with a plurality of pattern forming lenses for forming light patterns whose relative positional relation varies in conformity with the focus adjusted state of an objective optical system from lights passed through different areas on the pupil of the objective optical a sensing device is included for sensing the light patterns and producing a signal regarding the relative positional relation between the light patterns. A light divider is inclined along an optical path passing through the areas on the pupil and has a light-transmitting area through which light is refracted and transmitted. The light divider is disposed between the objective optical system and the pattern forming lenses. The pattern forming lenses are different in shape and are formed asymmetrically with respect to the optic axis of the objective optical system to correct the destruction of the light patterns caused by the light divider.

    • In a steering system that includes: an intermediate shaft on a steering wheel side; a pinion shaft on a steered wheel side; and a cross joint by which the intermediate shaft and the pinion shaft are rotatably connected to each other on a plane intersecting with each of the shafts, and that steers steered wheels by transmitting steering torque of a steering wheel from the intermediate shaft to the pinion shaft, a weakened portion is formed in a joint spider of the cross joint. The weakened portion can be identified in advance as a portion that breaks first. This makes it possible to realize a failure mode in which a vehicle is able to run by itself for a certain period of time after a failure.
