Abstract: A steering column device includes a coupling mechanism that couples an auxiliary restricting member with an inner column when a lock mechanism is in a locked position.

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.

Abstract: A magnetic head includes a microwave-generating element connected to a ground line. The ground line is made shorter by connecting the ground line to a conductive slider substrate so that the microwave-generating element is in a nearly short-circuited end condition. This allows a microwave excitation current to be efficiently supplied to the microwave-generating element, thus enabling effective microwave-assisted recording.
