１ａの上端に螺合されたシフトノブである。A similar gear shift lever of this type, for example, has been proposed by the present applicant in Japanese Patent Application No. 57-86755. According to Japanese Patent Application No. 57-86755, a cylindrical anti-vibration rubber 2 is interposed between a tubular upper lever 1a and a lower lever lb as shown in FIG. By forming a plurality of circumferential grooves 3a, 3b, and 3c in the upper lever 1a, an annular space R is formed between the upper lever 1a and the inward surface of the upper lever 1a. In addition, 4 is upper, <-
This is a shift knob screwed onto the upper end of 1a.

けるという不具合がある。Although this configuration can improve the vibration and sound insulation effects by keeping the spring constant of the anti-vibration comb 2 low, it also poses problems such as fatigue strength in the limit range, which is not a problem in practice. In this case, the fear of the vibration isolating rubber 2 against the operating force during the shift/select operation is due to the large diameter portion 2b on the lower end side.
As a result, there is a problem that the anti-vibration function of the large diameter portion 2b deteriorates and breaks due to changes over time, resulting in a lack of durability.
この発り１の目的とするところは、通常使用状態におけ
る防振・纒音効果を損９ことなく、その耐久性の向上を
図ったギヤシフトレバ−の構造を提供することにある。The purpose of this invention is to provide a gear shift lever structure that improves its durability without sacrificing vibration-proofing and noise-reducing effects in normal use.

いる。According to No. 11 of the present invention, a ring-shaped stopper is fixed to one of the upper lever and the lower lever near the lower end of the upper lever, which does not contact the other lever in normal conditions. There is.
以丁、この発明のよシ具体的な実施例を図面に基づき説

一符号を付すものとする。Hereinafter, more specific embodiments of the present invention will be described based on the drawings. However, the same parts as in the conventional example described above are given the same reference numerals.

／（−１ｂとストッパー５とが非接触で両者の間に所足
の隙間Ｓが存在するようにしである。FIG. 2 is a diagram showing a first embodiment of the invention. As shown in the figure, below the vibration isolating rubber 2, a ring-shaped stopper 5 made of, for example, hard rubber or synthetic resin is fixed to the inner periphery of the lower end of the upper lever 1a by adhesive, and the inner diameter of the stopper 5 is It is set larger than the diameter of the lower lever 1b. By the way, upper lever 1a
In a normal state in which no operating force is applied to the lower plate/(-1b) and the stopper 5, there is a sufficient gap S between them without contact.
尚、ロアレバー１ｂと防振ゴム２とは加硫接着等の常法
手段によシその全周面について固定されているものの、
アッパーレバー１ｍと防振コム２とはその大径部２ａ、
２ｂのみが接着されている。Although the lower lever 1b and the vibration isolating rubber 2 are fixed on their entire circumferential surface by conventional means such as vulcanization adhesive,
The upper lever 1m and the anti-vibration comb 2 have a large diameter part 2a,
Only 2b is glued.

防振ゴム２全体としてのはね定数ｉＬ低く＆す、）ラン

よび金属音が上記の接触部位にて吸収されて本来の機能
を発揮する。According to the above configuration, only the portions excluding the circumferential grooves 3m, 3b, and 3c are in contact with the inner circumference of the upper lever 1m.
The spring constant iL of the vibration isolating rubber 2 as a whole is low, and the minute vibrations and metallic sounds transmitted from the transmission to the lower lever lbK are absorbed at the above contact area to perform its original function.

ことになる。In addition, if an excessive operating force is applied when operating the gear shift lever, the vibration isolating rubber 2 will become stiff around the large diameter portion 2b, but it is possible for the large diameter portion 2b to bend to near its limit. Since the lower lever 1b and the inner periphery of the stopper 5 first come into contact and exert a so-called stopper effect, the large diameter portion 2b
will not bend any further. By limiting the amount of deflection of the large diameter portion 2b using the stopper 5, extreme deflection of the large diameter portion 2b is prevented and its durability is improved.

The upper lever 1a is fixed to the side, and a sufficient gap S is formed between the stopper 5A and the upper lever 1a in a normal state.
