PROBLEM TO BE SOLVED: To provide a shift lever device of automatic transmission capable of preventing breakage or the like by absorbing shock load applied via a shift lever with a simple constitution.SOLUTION: A guide plate 20 is pivotally supported on a lower support 1 fastened to a vehicle body, a first spring 26 and a second spring 29 compressed between the guide plate 20 and the lower support 1 are arranged and, when a shock load in the shift direction preset is applied on a stopper surface S of a guide 25 formed on the guide plate 20, the stopper surface S is configured so as to be moved in the shift direction. For example, when a shift lever 10 is subjected to shift operation without operating an operation button 19 such that a tip 16 of a guide rod 15 is brought into violent contact with the stopper surface S with an excessive shock load exceeding the preset shock load, the guide plate 20 is moved to absorb the shock load and, thereby, the shock to a constituent member of a shift lever device is reduced and the breakage of the constituent member or the like can be prevented.

    【課題】簡単な構成でシフトレバーを介して加わる衝撃荷重を吸収して破損等が防止できるシフトレバー装置を提供する。【解決手段】車体に固定される下部支持体1にガイドプレート20を軸支すると共にガイドプレート20の下部支持体1との間に圧縮付与された第1スプリング26及び第2スプリング29を配設し、ガイドプレート20に形成したガイド25のストッパ面Sに予め設定されたシフト方向の衝撃荷重が加えられた際に、ストッパ面Sがシフト方向に移動するように形動させる。例えば、操作ボタン19を操作することなくシフトレバー10をシフト操作してガイドロッド15の先端16がストッパ面Sに予め設定された衝撃荷重を上回る過大な衝撃荷重で激しく当接した際に、ガイドプレート20が移動して衝撃荷重を吸収することで、シフトレバー装置の構成部材への衝撃が減少して構成部材等の損傷が防止できる。【選択図】図2
