Abstract

A reaction force applying device includes an actuator housing, an actuator, a lever, a connected part, and a connecting part. The actuator housing is attachable to a vehicle. The actuator is provided in the actuator housing. The lever is provided in the actuator housing to be rotatable by receiving a driving force from the actuator, to contact an arm that rotates with a pedal, and to be capable of applying a reaction force to the pedal against a driver's stepping force. The connected part is provided in a pedal housing, and the connecting part is provided in the actuator housing and connected to the connected part.

Claims (34)

1. A reaction force applying device configured to apply, against a stepping force of a driver, a reaction force to a pedal of an accelerator device that includes: the pedal to be stepped by the driver; and a pedal housing provided to rotatably support the pedal and to be attached to a vehicle, the reaction force applying device comprising:

an actuator housing to be attachable to the vehicle;

an actuator provided in the actuator housing;

a lever provided at the actuator housing, to be rotatable by receiving a driving force from the actuator, to contact the pedal or an arm rotating with the pedal, and to apply the reaction force to the pedal with respect to the stepping force of the driver;

at least one connected part provided in the pedal housing; and

at least one connecting part provided in the actuator housing and directly connected to the at least one connected part without through the lever and the arm,

wherein the actuator housing is attached to the vehicle at a position away from the pedal housing by a predetermined distance.

2. The reaction force applying device of claim 1 , wherein

the at least one connected part is comprised of a plurality of connected parts, and

the at least one connected part is comprised of a plurality of connecting parts.

3. The reaction force applying device of claim 1 , wherein

a cross-sectional shape of the at least one connected part is a non-perfect circular shape, and

a cross-sectional shape of the at least one connecting part is a non-perfect circular shape.

4. The reaction force applying device of claim 1 , further comprising:

a bolt that fastens the at least one connected part and the at least one connecting part together.

5. The reaction force applying device of claim 1 , wherein

the at least one connected part and the at least one connecting part are connected by press fitting.

6. The reaction force applying device of claim 1 , wherein

the at least one connected part and the at least one connecting part are connected by snap fitting.

7. A reaction force applying device to apply a reaction force to a pedal of a vehicle against a pedal stepping force of a driver, the reaction force applying device comprising:

an actuator housing to be attached to the vehicle;

an actuator provided in the actuator housing;

a lever provided at the actuator housing, to be rotatable by receiving a driving force from the actuator, to contact the pedal or an arm rotating with the pedal, and to apply the reaction force to the pedal with respect to the stepping force of the driver;

a first connection part provided in a pedal housing in which the pedal is provided; and

a second connection part provided in the actuator housing and directly connected to the first connection part without through the lever and the arm,

wherein the actuator housing is attached to the vehicle at a position away from the pedal housing by a predetermined distance.

8. A reaction force applying device configured to apply, against a stepping force of a driver, a reaction force to a pedal of an accelerator device that includes: the pedal to be stepped by the driver; and a pedal housing provided to rotatably support the pedal and to be attached to a vehicle, the reaction force applying device comprising:

an actuator housing to be attachable to the vehicle;

an actuator provided in the actuator housing;

a lever provided at the actuator housing, to be rotatable by receiving a driving force from the actuator, to contact the pedal or an arm rotating with the pedal, and to apply the reaction force to the pedal with respect to the stepping force of the driver;

at least one connected part provided in the pedal housing; and

at least one connecting part provided in the actuator housing and connected to the at least one connected part,

wherein the actuator housing is attached to the vehicle at a position away from the pedal housing by a predetermined distance, and

a bolt that fastens the at least one connected part and the at least one connecting part together.
