Problems solved by technology

In such a bearing structure, generally, a predetermined gap (play) is provided in the radial and axial directions in consideration of the dimensional error caused by the machining deviation of the component parts, so that the pedal will step in. The hub part of the rotating part (vehicle pedal, etc.) is loosened or tilted relative to the support part due to the unbalanced load during operation, resulting in abnormal noise

Abstract

The present invention suppresses the occurrence of abnormal sounds and backlash caused by gaps between each section in a vehicle pedal device in which a flanged bushing is disposed between a support member and a boss. The two ends in the axial direction of the cylindrical section (46) of the flanged bushing (42, 44) are both contacted to the inner peripheral surface of the boss (40), and meanwhile a drum shaped section (54) is provided to the intermediate portion in the axial direction of the cylindrical section (46) and at least the minimum diameter section of the drum shaped section (54) is elastically contacted to the outer peripheral surface of a collar (26), and so the drum shaped section (54) is compressed and bent / deformed in the radial direction between the inner peripheral surface of the boss (40) and the outer peripheral surface of the collar (26). Consequently, the support rigidity of the boss (40) is secured by the reaction force resulting from the bending deformation of the drum shaped section (54), and so abnormal sounds, tilting, and backlash in the radial direction of the boss (40) are suppressed.

Description

technical field [0001] The present invention relates to a structure of a bearing portion of a pedal device for a vehicle, and more particularly to an improvement of a flanged bush disposed between a support member and a boss. Background technique [0002] A bearing portion structure of a pedal device for a vehicle is known in which a support member having a cylindrical outer peripheral surface is integrally arranged substantially horizontally on the pedal bracket, and the hub portion of the rotating member passes through a support member provided with a flange portion at one end of the cylindrical portion. A pair of resin flanged bushes are arranged on the outer peripheral side of the support member so as to be rotatable around the axis. In such a bearing structure, generally, a predetermined gap (play) is provided in the radial and axial directions in consideration of the dimensional error caused by the machining deviation of the component parts, so that the pedal will step...
