[0014] figure 1 4 shows an accelerator device according to a first embodiment of the present invention. The accelerator device 1 is an input device that is manipulated by a driver of a vehicle (for example, an automobile) to determine a valve opening degree of a throttle valve of the vehicle's internal combustion engine. The accelerator device 1 is an electronic device that transmits an electric signal indicating the amount of depression of the accelerator pedal 28 by the driver's foot of the vehicle to the electronic control device. The electronic control unit drives the throttle valve through an accelerator transmission mechanism (not shown) based on the depression amount of the pedal 28 and other information.

[0015] The accelerator apparatus 1 includes a support member 10 , a shaft 20 , a manipulation member 30 , a return spring 39 , a rotation angle sensor (serving as rotation angle sensing means) 40 , and a hysteresis mechanism 50 . In the following description, Fig...

[0061] Next, refer to Figure 5 An accelerator device according to a second embodiment of the present invention is described. In the second embodiment, the shape of the return spring at the time of full accelerator closing is different from that in the first embodiment. In the following description, components similar to those of the first embodiment will be designated by the same reference numerals, and will not be further described for simplicity.

[0062] Figure 5 A cross-sectional area of ​​the accelerator device of the second embodiment is shown.

[0063] The spring receiving portion 65 protrudes toward the front section 17 at the full closing side stopper portion 36 extending from the return raised portion 32 . The spring receiving portion 65 forms a return spring engagement surface 653 with which one end portion 691 of the return spring 69 is engaged.

[0064] While one end portion 691 of the return spring 69 is engaged with the return spring engaging surface 653 o...

Abstract

A first coil spring urges a shaft in an accelerator closing direction. A support member has a space, in which a first center line of the first coil spring is convexly curved when the shaft is rotated in an accelerator opening direction. The first center line is straight or is convexly curved toward the space when the limiting portion contacts the support member.

Description

technical field [0001] The invention relates to an accelerator device for a vehicle. Background technique [0002] The accelerator device controls the acceleration state of the vehicle based on the depression amount of an accelerator pedal (also referred to as an accelerator pedal) depressed by a driver's foot of the vehicle. The accelerator pedal is pushed in the accelerator closing direction by the spring. For example, JP2004-090755A describes an accelerator device that includes two return springs that push the accelerator pedal in the accelerator closing direction. [0003] However, in the accelerator device of JP2004-090755A, the return spring is arcuately bent to protrude in the radially outward direction of the rotation axis of the accelerator pedal when the accelerator is fully closed (ie, when the pedal is fully released). Therefore, the size of the housing of the accelerator device disadvantageously increases along the protruding direction of the return spring. ...
