Purpose of the invention (1) Industrial application field The present invention is a push-pull operation wire used to transmit the movement of a gear shift lever in an automobile to a change mechanism of a transmission. The present invention relates to a connection structure, and more particularly, to an improvement in a push-pull operating wire in which both ends of the inner wire are connected to an operating member and an operated member, and both ends of the outer wire of the operating wire are connected to a stationary part.

Structure of the invention (1) Means for solving the problems In order to achieve the above object, the invention provides the following features: one end of the inner wire and the operating member, the other end of the inner wire and the operated member, one end of the outer wire and the stationary part, An elastic member is interposed in at least one connection between the other end of the outer wire and the stationary part, and the elastic member includes a bottom spring constant part that receives a load when the inner wire is pulled, and a high spring constant part that receives a load when the inner wire is pushed. It is characterized by providing a spring constant part.

However, during the push operation, the high spring constant of the elastic member Since the load acts on the high spring constant section, the deformation of this high spring constant section is relatively small. As a result, even if the stiffness of the inner wire itself is lower on the push side than on the pull side, the stiffness of the entire operating force transmission system from the operating member to the operated member is equalized on the pull side and the push side.

された歯車列を確立させる。 To explain the operation of this embodiment, first,
If you turn the gear shift lever 3 in the selection direction Se,
The interlock lever 4 rotates to pull or push the inner wire Wi of the operating wire W2, which causes the select lever 8 to rotate and select a desired gear train of the transmission M. Next, when the gear shift lever 3 is rotated in the shift direction Sh, the lever 3 is connected to the operating wire W.
Directly pull or push the inner wire Wi of 1,
This rotates the shift lever 9 to establish the previously selected gear train.

縮変形が生じる。 By the way, when the inner wire Wi of the operating wire W2 is pulled by the interlocking lever 4, for example, a compressive force is applied to the low spring constant portion 16a of the elastic member 16 between the inner connecting ring 15 and the outer connecting ring 14.
In addition, since compressive force is applied to the low spring constant portion 24a of the elastic member 24 between the inner cylinder 19 and the outer cylinder 20 due to the reaction to the pulling of the inner wire Wi, a relatively large compressive deformation occurs in the low spring constant portions 16a and 24a. .

形は比較的小さい。 On the contrary, when the inner wire Wi is pushed by the interlocking lever 4, a compressive force is applied to the high spring constant part 16b of the elastic member 16, and a compressive force is also applied to the high spring constant part 24b of the elastic member 24. Compressive deformation of the spring constant portions 16b, 24b is relatively small.

その結果、インナワイヤWi自体の剛性におい

剛性は、引き側と押し側で均等化される。 As a result, even if the stiffness of the inner wire Wi is lower on the push side than on the pull side, the interlocking lever 4
The rigidity of the entire operation force transmission system from the select lever 8 to the select lever 8 is equalized on the pull side and the push side.

一方の弾性部材を省略することも可能である。 In addition, if the spring constants of the low spring constant part and the high spring constant part of the elastic member 16 or 24 are appropriately selected,
It is also possible to omit one of the elastic members.

Effects of the invention As described above, according to the invention, at least one connection portion between one end of the inner wire and the operating member, the other end of the inner wire and the operated member, one end of the outer wire and the stationary part, and the other end of the outer wire and the stationary part. The elastic member is provided with a low spring constant part that receives the load when the inner wire is pulled, and a high spring constant part that receives the load when the inner wire is pushed. It is possible to create a difference in the amount of deformation of the elastic member when pushing and pulling, and to equalize the pulling rigidity and pushing rigidity of the operating force transmission system from the operating member to the operated member,
Therefore, the operating feeling of the operating member can always be stabilized.
