Problems solved by technology

[0016] In the structure of the cam part 12' of the reset cam structure 10', there is the following problem: the above-mentioned steering lever is rotated to the left turn indicating position L (or right turn indicating position R), so that the reset cam side end 24 When in contact with the cam portion 12 ′, the contact sound (impact sound) between the cam portion 12 ′ of the reset cam structure 10 ′ and the reset cam side end 24 of the pawl 20 is loud, which is harsh to the driver.

Abstract

Provided are a cancel cam structure and a rotary connector device which are capable of reducing contact sound (hitting sound) of the cancel cam structure and a ratchet. Cam sections (12) are configured by outer peripheral cam walls (13a) allowing slide of a ratchet (20), inner walls (13b) radially inside than the outer peripheral cam walls (13a), and connecting cam walls (13c, 13d) connecting both ends of the outer peripheral cam walls (13a) and the inner walls (13b), the outer peripheral cam walls (13a), the inner walls (13b), and the connecting cam walls (13c, 13d) are formed in the direction parallel to the axial direction (X) of a steering shaft, surrounding spaces (S) surrounded by the outer peripheral cam walls (13a), the inner walls (13b), and the connecting cam walls (13c, 13d) are configured, and dividing walls (14, 140) dividing the surrounding spaces (S) are provided.

Description

technical field [0001] The invention relates to a reset cam structure and a rotary connector device. The reset cam structure and the rotary connector device rotate a steering lever indicating a turning direction of a vehicle from a left-turn indicating rotating position or a right-turn indicating rotating position through the rotation of a steering wheel. Return to the neutral position. Background technique [0002] When the vehicle driver is turning left, right or changing lanes, turn the steering joystick counterclockwise (turning left indicates the turning direction) or clockwise (turning right indicates the turning direction) to indicate the turning direction of the vehicle. Turn the steering wheel in the direction of turning in the neutral position. [0003] After that, when the vehicle completes a right turn, a left turn, or a lane change, the driver turns the steering wheel in the opposite direction of the above turning operation to return to the neutral position. A...
