Abstract
A pedal device includes a pedal, a connecting rod, a reaction force generating mechanism, a housing having a housing hole for allowing the connecting rod to pass therethrough when the pedal is stepped on by an operator, and a cover member. The cover member includes a first connecting portion and a covering portion. The first connecting portion is connected to a housing end portion of the housing forming a housing hole. The covering portion is arranged at a position between the first connecting portion and a back surface of the pedal and is connected to the first connecting portion to cover the housing hole.
Claims16
A pedal device comprising:
- a pedal configured to rotate about a rotation axis when stepped on by an operator;
- a connecting rod connected to a back surface of the pedal, opposite to a stepping surface stepped on by the operator, to rotate with the pedal about the rotation axis;
- a reaction force generating mechanism configured to generate a reaction force against a stepping force of the operator applied to the pedal by receiving a force from the pedal through the connecting rod and by an elastic deformation when the pedal is stepped on by the operator;
- a housing having a housing hole through which the connecting rod passes when the pedal is stepped on by the operator, and accommodating the reaction force generating mechanism;
- and
- a cover member including
- a housing connection portion connected to a housing end portion which is an end portion defining the housing hole in the housing, and
- a covering portion that is arranged at a position between the housing connection portion and the back surface of the pedal, and is connected to the housing connection portion, to cover the housing holes,
- the housing includes a first housing including the housing end portion, and a second housing,
- the first housing is provided with an opening at a position different from the housing hole, and a housing space communicating with the housing hole and the opening,
- the second housing is configured to close the opening of the first housing,
- a breathing hole is provided as a space between an opening-side end of the first housing and the second housing,
- the breathing hole is configured to discharge air in the housing space to an outside of the housing space after passing through the breathing hole, when the air in the housing space is compressed by receiving force from the pedal due to a stepping on of the pedal by the operator, and
- the breathing hole is configured to introduce air outside the housing space into the housing space through the breathing hole, when a force from the pedal is released due to stop of stepping on of the pedal subsequent to stepping on of the pedal by the operator to cause air in the housing space to expand.

- a cover member including
- a housing connection portion connected to a housing end portion which is an end portion defining the housing hole in the housing, and
- a covering portion that is arranged at a position between the housing connection portion and the back surface of the pedal, and is connected to the housing connection portion, to cover the housing hole;
- and
- a protection portion extending from the back surface of the pedal toward the housing to partially overlap with at least a part of the connecting rod and the cover member in an extending direction of the rotation axis, wherein
- a first region and a second region are provided at a position between the back surface of the pedal and the housing when the pedal is rotated to a farthest by the step-on operation of the operator,
- in a direction orthogonal to the pedal back surface, a distance from the back surface of the pedal to the housing in the second region is longer than a distance from the back surface of the pedal to the housing in the first region, and
- the protection portion is configured without covering the second region, to open the second region toward at least one direction of an extension line of the rotation axis, on which the protection portion is arranged.
