Problems solved by technology

Therefore, due to the gap, even if the driver depresses the accelerator pedal, the depressing force cannot be properly increased at the beginning of depressing
As a result, the formation of gaps can impair the operating feel of the accelerator pedal

[0018] figure 1 An accelerator device according to a first embodiment of the present invention is shown. The accelerator device 10 is an input device operated by a driver to control the operating state of an engine (not shown) of the vehicle. The accelerator device 10 has an electronic configuration for transmitting electrical signals to an electronic control unit (not shown). The electrical signal indicates the amount of depression of the accelerator pedal (accelerator pedal) 40 . The electronic control unit operates the throttle valve according to the electric signal transmitted from the accelerator device 10 .

[0019] First, refer to figure 1 with figure 2 The configuration of the accelerator device 10 is described. figure 1 with figure 2 The positional relationship of the accelerator device 10 mounted to the vehicle body 100 is shown. In the following description, the up-and-down direction of the accelerator device 10 mounted to the vehicle body 100 corresponds t...

[0036] will refer to Figure 7 An accelerator device according to a second embodiment of the present invention is described. Such as Figure 7 As shown, the first friction member 90 includes a slidable portion 91 , a first latch portion 92 and a second latch portion 93 . The slidable portion 91 is annular and slidable relative to the return rotor. The first latch portion 92 and the second latch portion 93 are arranged away from each other in the rotational direction. The first latch portion 92 and the second latch portion 93 are arranged on the inner side of the slidable portion 91 in the radial direction. The first latch portion 92 and the second latch portion 93 form a fitting groove (internal space) 94 therebetween. The matching groove 94 is in the shape of a notch.

[0037] The case (support member) 95 has a rotation restricting protrusion 96 . The rotation restricting protrusion 96 is fitted in a fitting groove 94 formed between the first latch portion 92 and the se...

Abstract

An accelerator pedal is supported by a support member. A biasing member biases the accelerator pedal to the full close position. A resistance application unit increases a frictional force to increase a rotational resistance applied to the accelerator pedal, as a rotation angle of the accelerator pedal increases. A slidable portion is mounted to the support member and slidable on the accelerator pedal. A first latch portion and a second latch portion define an interspace therebetween in a rotational direction. The support member includes a rotation restrictive projection fitted between the first latch portion and the second latch portion.

Description

technical field [0001] The invention relates to an accelerator device. Background technique [0002] A known accelerator device has an electronic configuration such that a sensor detects the depression amount of an accelerator pedal and transmits an electric signal representing the depression amount to an electronic control unit. Patent Document 1 discloses an accelerator device. The accelerator device includes a friction member provided between a pedal arm of an accelerator pedal and a spring rotor. The friction member has an annular portion and a rotation restricting protrusion. The annular portion is slidable relative to the pedal arm. The rotation restricting protrusion protrudes radially outward from the annular portion. The protruding portion has a tip that fits into a recessed portion formed in a wall of the housing to limit relative displacement in the rotational direction.
