Abstract: In a steering column device, a locking shaft is disposed on a vehicle front side relative to an operating shaft for an operating lever in parallel to the operating shaft. On the locking shaft, a cam member is disposed which is configured to press a locking member against a locked member via a guiderail in such a direction as to engage the locking member with the locked member. On the other hand, on the operating shaft, a linking member is disposed which is configured to bring the cam member into a state where the locking member and the locked member are disengaged from each other when the operating shaft is moved to an unlock position.

Abstract: On the outer peripheral surface of a part of a tilt operation shaft between sidewalls of a steering column, a pair of left and right protrusions are disposed opposite to each other which protrude outward in the radial direction. The pair of protrusions include mutually facing side surfaces formed as slanted parts defining a truncated V shape in a plan view such that the slanted parts get closer to each other as extending in the circumferential direction of the tilt operation shaft. When the tilt operation shaft is rotated, parts of a spring come into contact with the slanted parts of the protrusions and become elastically deformed, thereby pulling hold end parts of the spring out of tilt holes in wall surface parts of a tilt bracket.

Abstract: A vehicular shift apparatus includes an operation member configured to be put in five shift positions including a home position, a drive position, a reverse position, a drive-side neutral position, and a reverse-side neutral position. Nine sensing elements are provided to sense a magnet moved by movement of the operation member.

Abstract: In a steering column device, a small-diameter part of an operating shaft on one side of a step part on the operating shaft between a pair of clamp parts penetrates through an impact absorbing slot along a laminating direction. By operating an operating lever, the dimension of cam mechanism in the direction of the operating shaft is increased. Consequently, between the step part and an inner face of the other clamp part, a movable-side friction plate is brought into pressure contact with a stationary-side friction plate to be held. In this situation, when a load exceeding a set value is applied to the steering column device, the movable-side friction plate slides on the stationary-side friction plate to absorb the impact.
