Claims

[Claims for Utility Model Registration] A fixing bracket that fixes to a part of the vehicle body a column tube that rotatably supports a lower shaft connected to a gear box, and a steering wheel that is connected to the lower shaft so as to be tiltable in the vertical direction. A rotating bracket is provided on a column tube that rotatably supports an upper shaft that supports a wheel, and is pivotally connected to the fixed bracket so as to be tiltable in the vertical direction; A ratchet having a pair of arcuate teeth on opposing parts, a part of an arcuate cover covering one of the arcuate teeth of the ratchet, and a part of the arcuate cover that is removably engaged with the arcuate teeth on its inner periphery. 2. A pivoting portion of both brackets on one side of the ratchet. A pair of cover plates are assembled to be rotatable and movable in the radial direction, and the cover plates are locked by releasably engaging with a retaining portion provided on a portion of the outer periphery of each cover plate. a pair of first operating levers each having an engaging portion and rotatably attached to the fixed bracket or a part of the vehicle body and resiliently abutting on the outer periphery of a portion of the cover of the cover plate; a second operating lever rotatably assembled to the pivot joint and held in a neutral position by a spring force; and a second operating lever provided between the second operating lever and each of the cover plates. a pair of first cam mechanisms that selectively separate the respective cover plates that engage with the ratchets from the ratchets by a rotational operation; A pair of second cam mechanisms are provided for selectively separating the first operating lever that contacts the cover plate on the side that engages with the ratchet from the cover plate by rotating the second operating lever.
