Reaction force application device

A reaction force application device configured to apply a reaction force against a pedal force of a human driver to a pedal of an accelerator device to be depressed by the human driver, the reaction force application device comprising:

• an actuator that is configured to generate a drive force in response to energization of the actuator;
• a lever that is configured to be rotated by the drive force transmitted from the actuator to apply the reaction force to one of the pedal and an arm, wherein the arm is configured to be rotated integrally with the pedal;
• and
• a contact member that is provided to the lever, wherein the contact member is configured to be brought into contact with or separated from the one of the pedal and the arm, wherein:
• the lever includes:
• a lever main body that is shaped in a rod form;
• a one-side lever end portion that is formed at one end of the lever main body and is configured to receive the drive force transmitted from the actuator;
• and
• an other-side lever end portion that is formed at another end of the lever main body, which is opposite to the one end of the lever main body;
• the contact member is made of resin and has:
• a contact member main body that is shaped in a tubular form;
• a contact surface portion that is formed in a specific range of an outer peripheral surface of the contact member main body and is configured to contact the one of the pedal and the arm;
• and
• a specific shape portion that is shaped in a form of a projection or a recess and is formed on the contact member main body at a time of molding the contact member, wherein the contact member is provided to the lever such that the other-side lever end portion is inserted through an inside of the contact member main body;
• the specific shape portion is formed on the contact member main body at a corresponding location that is different from the contact surface portion;
• the contact member has a slidable surface portion that is formed in a specific range of an end surface of the contact member main body, which faces in an axial direction of the contact member main body, wherein the slidable surface portion is configured to rotate relative to the other-side lever end portion and is slidable relative to another member;
• and
• the specific shape portion is formed on the contact member main body at the corresponding location that is different from the slidable surface portion.
