Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a cable mounting structure that links a throttle valve of an automatic transmission and a throttle valve of an engine.

2. Description of the Related Art Conventionally, as an example of a link structure using a cable, an automatic transmission is provided with a throttle valve that adjusts a line pressure by being linked to a throttle valve of an engine via a cable. Then, a clutch engagement pressure according to the engine output is required. For example, when the engine output is low, the shift shock increases when the clutch engagement pressure is high, so that the throttle valve of the engine and the throttle valve of the automatic transmission are tightly closed. It is necessary to perform an operation linked to.

For this purpose, as a coordination mechanism between the two, for example, JP
As disclosed in Japanese Patent Publication No. -30534, the accelerator pedal and the throttle lever of the automatic transmission are connected by a cable, and the throttle lever and the throttle cam for driving the throttle valve of the engine are connected by another cable. Known structures are known.

(Problems to be Solved by the Invention) However, in the connection structure using the above-described cables, when adjusting the mounting position of the outer cable with respect to the inner cable to improve the accuracy of the synchronous operation in the connection between the operation members, the outer connection is simply performed. In the mounting structure in which the end of the cable is fixed by adjusting the tightening position of the adjusting screw in the axial direction, it is difficult to secure sufficient accuracy by a simple mounting and adjusting operation.

In other words, even if the position of the outer cable is adjusted so that there is no slack in the inner cable, and the outer cable is in the predetermined tension state, if it is actually tightened to fix it, it will move in the axial direction and the accuracy of the position adjustment will deviate. become. In the case where the adjustment accuracy is obtained by dimensional control, for example, the reference point is determined by setting the operating member of one throttle valve to a fully closed or fully open state, and the protrusion amount of the inner cable with respect to the outer cable is dimensionally controlled. In the case of mounting in a range, the error in the actual tension state may be large and the adjustment accuracy may be low.

In view of the above circumstances, the present invention considers the first operating member and the second operating member.

While being connected to the operating member, one end of the outer cable is fixed to a fixed portion near the first operating member, and the other end of the outer cable is detachably held by a mounting bracket attached to the fixed portion near the second operating member. A holding device which is adjustably mounted via a member and has a mounting portion which can be fixed to a mounting bracket and a holding portion having a U-shaped cross section for supporting an outer cable so as to be slidable in the axial direction of the cable. The member, the elastic member for stretching the outer cable and the inner cable with a predetermined load relatively, and the sliding of the outer cable and the holding portion caused by the elastic force of the elastic member by loosening are allowed and tightened. Fastening means consisting of bolts and nuts for restricting the sliding against the elastic force. The holding member is attached to the mounting bracket with the fastening means loosened. By the elastic member put is characterized in that fixed to the holding portion outer cable by tightening the fastening means in a state where tension is applied to the outer cable and inner cable.
