Description

[Detailed description of the invention] This invention relates to an improvement in the connection structure of cable terminals of control cables in automatic transmissions of automobiles, and is particularly concerned with facilitating the position adjustment of cable terminals in narrow connection areas and improving assembly workability. The purpose is to improve.

In automobiles equipped with an automatic transmission, the transmission and the shift lever of each range switching shift lever device mounted on the floor of the vehicle body are usually connected by a flexible cable of a predetermined length consisting of an inner cable and an outer cable. The shift lever operation is transmitted to the transmission via an inner cable to switch to each range. However, due to installation errors in the transmission and shift lever device, the dimensions between the two did not match the expected dimensions, resulting in slight variations. For this reason, when connecting the cables, the length of the cables is adjusted via a turnbuckle or the like, or the connection position of the cable terminal on the shift lever side is adjusted to absorb attachment errors.

For example, when adjusting the mounting position of a cable terminal on the shift lever side and connecting them, conventionally, a mounting hole is formed in a bracket that is integrally mounted to the shift lever, and a washer, bushing, grommet, etc. is inserted into the mounting hole. The connecting bolt is protruded to allow slight rotation, and a cotter pin is fitted into the end of the connecting bolt to prevent it from coming off from the mounting hole.On the other hand, a long hole is formed in the inner cable terminal to prevent the cable from coming off when connected. After loosely fitting the long hole of the terminal into the protrusion of the connecting bolt and adjusting the position by moving the cable terminal back and forth, hold this state and tighten the nut using the washer to attach the cable terminal to the connecting bolt. It was strongly connected.

However, although the connection structure described above allows adjustment of the connection position of the cable terminal, it requires a large number of parts.
It takes time to assemble, and the shift lever device has a moderation mechanism to prevent malfunction of the hydraulic valve of the transmission in each range. A moderation mechanism that provides a sense of moderation, a position indicator that indicates the shift position of the shift lever, and a neutral safety switch are integrated and incorporated, and the space around the bracket that connects the cable terminal is It's so narrow that you can barely fit your finger into it. Therefore, it is extremely difficult to assemble each component within such a narrow space, resulting in poor workability. Another drawback was that the cable terminal connection part became loose due to the installation of the connecting bolt, which impaired the feel of operating the shift lever.

This invention is an improvement and elimination of the above-mentioned conventional drawbacks. Namely, in a shift lever device of an automatic transmission, a shift lever is pivotably mounted on a casing fixed to a stationary member of the vehicle body. is integrally attached to the lever and the lower part of the shift lever,
A cable connecting bracket having a long hole along the cable connecting direction in a part thereof, and a cable connecting bracket that is attached to the bracket so as to be slidable in the direction of the long hole, and a bolt insertion hole and the bolt insertion hole at a position corresponding to the long hole. The holder has a projection nut fixed to the outside of the holder, and has a threaded part at the tip that is screwed into the projection nut of the holder, and has a larger diameter than the threaded part and has a loose end to the eye of the cable terminal. It consists of a stepped bolt that has a step that can be fitted into the rear end, and the stepped bolt and the projection nut of the holder connect the cable terminal to the shift lever.
The bracket can be connected at any position within the elongated hole.

A pressing member (not shown) attached to the shift lever 2 is always in elastic contact with the wave toothed portion 6 at a moderation position corresponding to the shift position of the shift lever 2, and as the shift lever 2 is operated to change the shift position, , it is configured to overcome the wave portion and enter the adjacent moderation position, giving a sense of moderation when switching. 7 is a cable terminal mounting bracket integrally welded and fixed to the lower part of the shift lever 2, and as shown in FIGS. 2 and 3, a long hole 8 is formed in the center of the tip along the longitudinal direction; The width is narrowed by notching the lower edge from the center to the tip.
In addition, bulges 9, 9 are formed on the upper and lower edges of the tip.
Reference numeral 10 denotes a holder slidably attached to the bracket 7. The upper and lower ends are bent in the same direction into a U-shape to form guide grooves 11, 11 facing each other, and a bolt insertion hole 12 is formed in the center to accommodate the bolt. A projection nut 13 is welded and fixed to the back side of the insertion hole 12. The dimension between the guide grooves 11, 11 of the holder 10 is set to a dimension that allows the holder 10 to fit loosely into the bracket 7 without interfering with the bulges 9, 9 of the bracket 7. Also, the upper and lower end surfaces 10a and 10b of the holder 10
A part is cut and raised inward, and guide grooves 11, 11 are formed from the insertion side to the bracket 7 to the opposite side.
Inwardly protruding tongue pieces 14, 14 are formed. Therefore, when attaching the holder 10 to the bracket 7,
The tongue pieces 14, 14 can be attached by bending outward along the bulges 9, 9 of the bracket 7, and once attached,
The tongue pieces 14, 14 protrude into the guide grooves 11, 11, and their end surfaces abut against the bulges 9, 9 to prevent the holder 10 from being pulled out. Reference numeral 15 denotes a stepped bolt that connects the cable terminal 19 of the inner cable 18. The threaded end portion 16 of the stepped bolt 15 is inserted into the elongated hole 8 of the bracket 7, and the holder 10 is secured to the bracket 7 by tightening it to the projection nut 13 of the holder 10. Secure in place. Then, the eye part 20 of the cable terminal 19 is attached to the stepped part 17 of the stepped bolt 15.
are rotatably fitted and connected. The width of the stepped portion of the stepped bolt 15 is formed to be slightly longer than the width of the eye portion 20 of the cable terminal 19,
