Energy absorbing steering devices may include an outer cylindrical member (OU) that is press-fited around an inner shaft member (IN). The outer shape of the inner shaft member and the inner shape of the outer cylindrical member have a circular cross-section and the diameter of the inner shape of the outer cylinder member is larger than the diameter of the outer shape of the inner shaft member. A plurality of fine members (W) is disposed along the axial direction between the circular cross-sectional outer shape and the circular cross-sectional inner shape in order to provide a clearance (G) between the inner shaft member and the outer cylindrical member. The arrangement of the fine members may be modified in order to adjust the rigidity of relative movement along the axial direction of the outer cylindrical member and the inner shaft member.

Energy absorbing type steering device, and method and device for assembling the steering device

A support mechanism of a steering system that supports a steering column to a part of a vehicle body includes an energy absorbing member mounted on the side of a steering column or the vehicle body, a support pin mounted on the side of the vehicle body or the steering column, that deforms the energy absorbing member when the steering column moves relative to the vehicle body, and an actuator mounted on the side of the steering column or the vehicle body, that changes deformation characteristics of the energy absorbing member.

Support mechanism of steering system

A keyhole is formed on an operating knob installed on the front surface of a rotary switch. The rotary switch can therefore be operated by inserting into the keyhole an electronic key having a long and narrow shape and then turning the operating knob. As a result, operations for an engine start using the electronic key are the same as those using a conventional key.

Vehicle electronic key system

An actuator portion,provided separately from an operating portion includes a lock member,for locking a steering shaft,, a motor,, and a lock control mechanism,. The lock control mechanism,has a driven body,rotated by the motor,through a gear mechanism,, a cam member,for moving the lock member,, and an unlock spring member,constituted by a torsion coiled spring and disposed between the driven body,and the cam member,. When the motor,is subjected to an unlocking operation in the condition that handle torque acts on the lock member,, the spring force of the unlock spring member,is accumulated while the unlock spring member,absorbs the rotational displacement of the driven body
