Straddled vehicle equipped with eps

A straddled vehicle equipped with electric power steering (EPS), the straddled vehicle comprising:

• a front steerable wheel;
• a steering mechanism, including:
• a handlebar configured to be manipulated by a rider of the straddled vehicle,
• a steering shaft extending in an up-down direction of the straddled vehicle,
• the steering mechanism being configured such that the manipulation of the handlebar by the rider is mechanically transmitted to steer the front steerable wheel;
• and
• an EPS actuator configured to apply an auxiliary steering force corresponding to the manipulation of the handlebar to the front steerable wheel, the EPS actuator including a motor, and a transmission gear part configured to transmit an output of the motor to the steering shaft, wherein
• the motor includes:
• a rotor shaft arranged rotatably about an axis line extending in the up-down direction of the straddled vehicle,
• a rotor gear part provided to the rotor shaft, the rotor gear part being meshed with the transmission gear part, each of the rotor gear part and the transmission gear part having a tooth space thereof extending in the up-down direction,
• an upward dynamic thrust load attenuation elastomer member disposed to allow the rotor shaft to move in an upward direction of the straddled vehicle, and to receive and attenuate a first dynamic thrust load that is produced as the straddled vehicle travels and is applied in the upward direction, and
• a downward dynamic thrust load attenuation elastomer member disposed to allow the rotor shaft to move in a downward direction of the straddled vehicle, and to receive and attenuate a second dynamic thrust load that is produced as the straddled vehicle travels and is applied in the downward direction;
• the upward dynamic thrust load attenuation elastomer member is configured to compress in the upward direction in response to the first dynamic thrust load, so as to attenuate the first dynamic thrust load, a maximum compression amount of the upward dynamic thrust load attenuation elastomer member at a time of receiving the first dynamic thrust load being less than a height of an upward movement allowance space provided to allow the rotor shaft to move in the upward direction when the first dynamic thrust load is received;
• the downward dynamic thrust load attenuation elastomer member is configured to compress in the downward direction by receiving the second dynamic thrust load, so as to attenuate the second dynamic thrust load, a maximum compression amount of the downward dynamic thrust load attenuation elastomer member at a time of receiving the second dynamic thrust load is less than a height of a downward movement allowance space provided to allow the rotor shaft to move in the downward direction when the second dynamic thrust load is received;
• and
• a sum of the maximum compression amount of the upward dynamic thrust load attenuation elastomer member and the maximum compression amount of the downward dynamic thrust load attenuation elastomer member is shorter than a length of the rotor gear part or that of the transmission gear part, whichever is longer, in the up-down direction.
