1. A steering wheel comprising:
a steering portion which is gripped and steered by a driver;
a boss portion which is disposed inside the steering portion and is coupled to a steering center shaft of the steering portion; and
an operation portion which is disposed adjacent to the steering portion, and is configured to be swingable with respect to the steering portion, to input an accelerator operation by being operated to swing in a first direction with respect to the steering portion, and to input a brake operation by being operated to swing in a second direction opposite to the first direction, wherein:
the operation portion is a right operation portion disposed on a right side with respect to the boss portion,
the steering wheel further comprises a left operation portion which is disposed on a left side of the boss portion, and is configured to be swingable with respect to the steering portion, to input the accelerator operation by being operated to swing in a third direction with respect to the steering portion, and to input the brake operation by being operated to swing in a fourth direction opposite to the third direction,
swing of the right operation portion in the first direction and swing of the left operation portion in the third direction are synchronized with each other, and the swing of the right operation portion in the second direction and the swing of the left operation portion in the fourth direction are synchronized with each other, by a power transmission mechanism mechanically transmitting power of one of the right operation portion or the left operation portion during swinging to other of the right operation portion or the left operation portion,
a right swing shaft, which is a swing shaft of the right operation portion, is disposed along a direction intersecting with a left-right direction at the right side of the boss portion,
a left swing shaft, which is a swing shaft of the left operation portion, is disposed substantially parallel to the right swing shaft at a position symmetrical to the right swing shaft with respect to the boss portion, and
the power transmission mechanism is a link mechanism including
a rotary member in which a rotary shaft is disposed so as to be substantially parallel to the left swing shaft at a position with substantially equal interval to each of the left swing shaft and the right swing shaft in the left-right direction,
a first link coupled to the rotary member and configured to rotate the rotary member in a first rotation direction by moving in conjunction with a swing operation of the right operation portion in the first direction, and to rotate the rotary member in a second rotation direction opposite to the first rotation direction by moving in conjunction with a swing operation of the right operation portion in the second direction, and
a second link coupled to the rotary member at a position symmetrical to a coupling position between the first link and the rotary member with respect to the rotary shaft, and configured to rotate the rotary member in the first rotation direction by moving in conjunction with a swing operation of the left operation portion in the third direction, and to rotate the rotary member in the second rotation direction by moving in conjunction with a swing operation of the left operation portion in the fourth direction.
