Abstract
A steering lock device includes a motor configured to rotate a motor shaft, a worm attached to the motor shaft of the motor, a main gear configured to rotate along with rotation of the worm, a cam member integrally provided with the main gear, and a rod including an insertion and extraction portion. The insertion and extraction portion is configured to be inserted into and extracted from an opening provided on a steering shaft side in accordance with an operation of the cam member along with rotation of the main gear. At least a part of at least one member of the worm and the insertion and extraction portion is configured to be accommodated in a circumferential region of the main gear when the main gear is viewed in a plan view along a rotation axis direction of the main gear.
Claims5
A steering lock device comprising:
- a motor configured to rotate a motor shaft;
- a worm attached to the motor shaft of the motor;
- a main gear configured to rotate along with rotation of the worm;
- a cam member integrally provided with the main gear;
- and
- a rod including an insertion and extraction portion,
- wherein the insertion and extraction portion is configured to be inserted into and extracted from an opening provided on a steering shaft side in accordance with an operation of the cam member along with rotation of the main gear, and
- wherein at least a part of the worm and at least a part of the insertion and extraction portion are configured to be accommodated within and overlapping a circumferential region of the main gear between an outer periphery of the main gear and a rotation axis of the main gear when the main gear is viewed in a plan view along a rotation axis direction of the main gear.
A steering lock device comprising:
- a motor configured to rotate a motor shaft mounted on a frame member and extending along a planar portion of the frame member;
- a worm attached to the motor shaft of the motor;
- a two-stage gear configured to rotate along the planar portion and including a first gear engaged with the worm and a second gear having a second rotation axis that is coaxial with a first rotation axis of the first gear;
- a main gear configured to rotate along the planar portion and including internal teeth engaged with the second gear of the two-stage gear;
- and
- a rod configured to transition between two states along with rotation of the main gear,
- wherein the two states are a restriction state that rotation of a steering shaft is restricted and a cancel state that the restriction is canceled.
