Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control cable mounting structure. More specifically, the present invention relates to a structure for attaching a terminal or an intermediate portion of a control cable conduit to a mating member such as a vehicle panel.

[0002]

2. Description of the Related Art Generally, a control cable comprises a conduit and an inner cable slidably moving in the conduit. Then, the terminal of the conduit is locked or fixed to a panel or the like of the vehicle, and one end of the inner cable is driven to pull or push / pull the driven member connected to the other end. When locking the end of the conduit to the panel of the vehicle, etc., a bracket of a predetermined shape is fixed to the mating member in advance, and a specific terminal member corresponding to the bracket is fixed to the end of the conduit, and actual assembly is performed. In operation, it is common to attach the terminal member to the bracket with one touch.

As an attachment structure capable of easily locking the terminal of the control cable conduit to a counterpart member, there is known an attachment structure 101 of an axial insertion type as shown in FIG. The structure 101 includes a plate-shaped bracket 104 having a circular opening 102 and a communication groove 103 communicating the opening 102 with an edge, and a conduit 1.
And a cylindrical end member 106 fixed to the end of the end portion 05. The terminal member 106 is the opening 102 of the bracket 104.
Insertion part 107 which can be inserted in the
Step portion 108 which comes into contact with the periphery on the back side of
7 and an elastic claw 109 for holding the periphery of the bracket 104 between the stepped portion 108 and the stepped portion 108.

[0004] When this is attached, first, an inner cable, a rod connected to the inner cable, or a guide pipe 110 for slidably guiding the rod is positioned in the opening 102 through the communication groove 103, and then inserted. Part 107
Is axially pressed into the opening 102 of the bracket 104. As a result, the elastic claw 109 bends inward, the elastic claw 109 expands after passing, and the bracket 104 is attached to the elastic claw 10.
9 and the step 108 can be sandwiched. Thus, the structure 101 can be attached to the bracket 104 with one touch. However, at the time of removal, a tool for bending the elastic claw 109 inward is required. In the case of a push-pull cable, the tensile force applied to the conduit 105 in the axial direction is supported by the elastic claws 109. Therefore, when the load is large, large elastic claws are required, which is disadvantageous in terms of space. Therefore, it is not suitable for large loads.

On the other hand, as shown in FIG. 8, there is also known a mounting structure 111 of a so-called right-axis insertion type, which is inserted in a direction perpendicular to the axis (see Japanese Patent Application Laid-Open No. Hei 8-135645). This structure has a U-shaped notch 1
The bracket 104 includes a plate-shaped bracket 104 having an inner hole 12 and an engagement hole 113 therebelow, and a terminal member 115 locked to the bracket 104. The terminal member 115 is the bracket 1
A pair of locking flanges 116 and 117 that come into contact with the front and rear surfaces of
And the engagement groove 112 of the bracket interposed therebetween.
And an insertion portion 118 fitted from above. Therefore, guide grooves 119 are formed on both left and right sides of the front and rear locking flanges 116 and 117. Further, a frame-shaped support portion 120 extends downward from the lower end of the front locking flange 116, and the support portion 1
A locking piece 121 that elastically engages with the engagement hole 113 extends upward from 20. The front and rear locking collars 116, 1
Between the upper ends of 17, a wavy pressing portion 122 is passed.

[0006] This is the engagement flange 11 of the terminal member 115.
6, 117 are aligned with the front and rear surfaces of the bracket 104, the pressing portion 122 is pressed, and the insertion portion 118 is
04 into the engagement groove 112 from above, and
Is attached by engaging with the engaging hole 113. In this state, the locking piece 121 is locked in the engagement hole 113,
Has a retaining action. The axial force applied to the conduit 105 is firmly supported by the bracket 104 via the front and rear engagement flanges 116 and 117.

Although this structure has an advantage that it can be attached with one touch, it is difficult to set the thickness of the bracket 104 and the size of the gap between the front and rear engagement flanges 116 and 117, and if the thickness is too large, the attachment becomes difficult. If it is too thin, play will occur. In addition, when removing, it is necessary to bend the locking piece 121 with a tool to release the engagement with the engagement hole 113 and remove it.

Japanese Patent Application Laid-Open No. 10-210634 describes another example of a mounting structure of a type which is inserted in a direction perpendicular to an axis. As shown in FIG. 9, this mounting structure includes, in addition to the bracket 104 and the terminal member 115 described above, a spacer 124 interposed between the bracket 104 and the terminal member 115 to suppress backlash in the axial direction. The spacer 124 is formed by bending a single leaf spring at the center to form a first interposed portion 125 interposed between the front engagement flange 116 on the front side of the bracket 104 and the engagement flange on the rear and rear sides of the bracket 105. And a second interposed portion 126 interposed between the two. The tongue piece 12 elastically engaged with the slit 127 of the bracket 104 is provided on the spacer 124.
8, and a locking piece 130 that engages with the recess 129 of the front engagement flange 116 is provided so that the locking piece 130 also has a retaining action.

Although no backlash is produced in the axial direction, the engagement and disengagement of the spacer 124 and the terminal member 115 and the engagement and disengagement of the spacer 124 and the bracket 104 are required. It is complicated and requires tools for it.

[0010]

SUMMARY OF THE INVENTION The present invention can be easily removed without using a tool while maintaining the advantage that the end of the control cable can be attached to a mating member with one touch, and the plate of the bracket can be easily removed. It is an object of the present invention to provide a control cable mounting structure with less play in the axial direction even if the thickness accuracy is low.

[0011]

The control cable mounting structure according to the present invention has an opening for fitting at a position distant from the edge, and is provided between the edge and the opening. A bracket having a notch with a narrow width, and a mounting member for mounting the control cable in a state where the control cable passes through the opening with respect to the bracket. An insertion portion having a width that can be inserted into the notch portion from the opening portion, a fitting step portion that fits into the opening portion, and a flange portion that engages around the opening portion are sequentially provided in the axial direction, and along the center portion. And a main body for holding the control cable, and the main body is movably provided on the main body so as to take a position close to and away from the flange portion, and engages around the opening of the bracket. And Kkupisu is characterized in that it comprises a means for constraining the lock piece in a state of being pressed to the side of the flange portion.

As the restraining means, a spring for urging the lock piece in the direction of moving the lock piece toward the flange side can be employed. In this case, it is preferable to provide a booster mechanism for increasing the urging force of the spring to press the lock piece toward the flange. Such a booster mechanism is composed of a first inclined surface that intersects at a predetermined angle with a center line of the main body formed on the main body, and a second inclined surface that slides on the first inclined surface formed on the lock piece. Can be constituted by a cam mechanism. In this case, it is preferable that the spring is provided so as to bias the lock piece to the side approaching the flange side along the inclined surface. It is further preferable that the angle between the center line of the main body and the first inclined surface is an angle that restricts movement based on an axial force away from the flange applied to the lock piece by frictional force generated between the inclined surfaces. .

Further, the restraining means may be constituted by a link mechanism comprising a lever provided rotatably with respect to the main body, and a link connecting the lever and the lock piece. In that case, it is preferable to provide the lock piece in the insertion portion of the main body so as to be slidable in the axial direction. Preferably, the link also serves as a spring for urging the lock piece toward the flange.

[0014]

The mounting structure of the present invention is different from the conventional structure of the axial fitting type and the structure of the right angle fitting type. It is an eclectic type of both which is attached by inserting into That is, when attaching the main unit with the control cable to the bracket,
The lock piece is operated in a direction away from the flange portion, and in this state, the main body to which the control cable is attached is arranged above the bracket such that the fitting step is behind the rear surface of the bracket. Next, the insertion part of the main body is inserted at right angles from between the notches of the bracket. In this state, there is a sufficient space between the lock piece and the flange portion, so that the lock piece can be easily inserted.

Then, the fitting step is fitted into the opening, and the main body is moved to the front end in the axial direction until the flange contacts the rear side of the bracket. Then, the lock piece is operated in a direction approaching the flange portion, the lock piece is pressed toward the flange side by the restraining means, and the bracket is pressed between the lock piece and the flange portion to be restrained in that state.

As described above, in the mounting structure of the present invention,
The control cable can be attached to the bracket with one touch. Then, once attached, the main body does not come out upward because the fitting step is larger than the notch. In addition, the fitting step portion and the opening do not fall down and left and right. Also, since the bracket is inserted between the lock piece and the flange part of the main body that holds the control cable, it does not move in the axial direction,
In addition, even if the accuracy of the thickness of the bracket is low, there is no backlash in the axial direction.

Conversely, when removing the control cable from the bracket, the pressing of the lock piece by the lock piece by the restraining means is released, and the lock piece is moved in a direction away from the bracket (forward). As a result, the main body is movable in the axial direction, so that the main body is retracted until the fitting step is disengaged from the opening. Then, the insertion portion is pulled out in a direction perpendicular to the axis while passing through the notch portion.

As described above, in the mounting structure of the present invention, since the main body is provided with the flange portion and the lock piece which can be approached / separated from the flange portion, the constraint of the lock piece to the bracket can be achieved without using a tool. Just release it and you can easily remove the body from the bracket.

When a spring that urges the lock piece in the direction of moving the lock piece to the flange side is employed as the restraining means, the restraining force can be maintained for a long period of time. When the urging force of the spring is increased by the booster mechanism, a small spring can be used and the design can be made compact. When a predetermined cam mechanism is used as the booster mechanism, the operation force for moving the lock piece to the side opposite to the flange against the urging force of the spring is small, so that the main body can be more easily attached to and detached from the bracket. When the angle of the inclined surface is smaller than the predetermined angle, the movement of the lock piece along the inclined surface can be restricted by the frictional force based on the axial force applied to the lock piece. Therefore, the restraining action is further ensured.

When a predetermined link mechanism is used as the restraining means, the attachment / detachment is facilitated by the boosting action of the link mechanism. Further, when the lock piece is provided in the insertion portion so as to be slidable in the axial direction, the positioning of the lock piece becomes easy. When the link of the link mechanism is also used as a spring for urging the lock piece toward the flange, the restraint can be further ensured.

The mounting structure A shown in FIG. 1 has a mounting member 2 fixed to an end of a conduit 1 of a control cable.
And a bracket 3 to which the attachment member 2 is attached. The mounting member 2 includes a main body 4, a lock piece 5 slidably mounted on the main body in an oblique direction, and a spring 6 for urging the lock piece 5 upward.

An end of a casing cap 7 fixed to one end of the conduit 1 is locked inside the front side of the main body 4. Inside the rear portion, one end of a guide pipe 8 is swingably supported, and a rod 10 to which an end of an inner cable 9 is fixed is accommodated in the guide pipe 8 so as to be slidable in the axial direction. I have. The casing cap 7 is attached to the main body 4.
Alternatively, the entirety to which the guide pipe 8 is attached can be considered as the main body. The conduit 1 and the inner cable 9 slidably accommodated therein constitute a push-pull control cable. The guide pipe 8 and the rod 10 are known as a cable end connecting member on the operating side or the operated side of the push-pull cable.

The bracket 3 is a plate-shaped member and has a circular opening 12 at a position distant from the upper edge, and a notch 13 continuous to the upper edge of the bracket 3 is provided at the upper end of the opening. Is formed. The opening 12 may be rectangular or the like. The width of the notch 13 is smaller than the inner diameter of the opening 12, so that a hook portion 14 is left above the inner edge of the opening 12. In addition, the upper end of the inner edge of the notch 13 is notched obliquely so that the mounting member 2 can be easily inserted.

The main body 4 of the mounting member 2 has a rectangular parallelepiped conduit holding portion 16 and a flange portion 17 provided at a rear end thereof. The flange portion 17 is square, but may be circular. The left and right widths of the conduit holding part 16 are smaller than the vertical dimension, and are substantially matched with the width of the notch 13 of the bracket 3. The width and height of the flange 17 are larger than the inner diameter of the opening 12 so that the flange 17 can come into contact with the back surface of the bracket 3. The lower surface 18a near the rear end of the conduit holding portion 16 has a cylindrical surface so as to match the inner surface shape of the opening 12 of the bracket 3 (see FIG. 3B). A portion of the conduit holding portion 16 near the rear portion having the cylindrical surface is cut out from the notch 13 of the bracket 3 to the opening 12.
The insertion portion 18 can be inserted in a direction perpendicular to the axis (downward in FIG. 1).

Further, on the left and right side surfaces of the base of the conduit holding portion 16, fitting steps 19 rising from the front surface of the flange portion 17 are provided. The side peripheral surface of the fitting step 19 is formed in an arc shape so as to fit with the inner periphery of the opening 12 of the bracket 3, and is continuous with the cylindrical lower surface 18 a of the insertion portion 18. The thickness of the fitting step 19 is smaller than the thickness of the bracket 3. However, it may be thicker than the thickness of the bracket 3, in which case a relief is formed in the lock piece 5.

A guide ridge 20 for guiding the lock piece 5 is provided on the front side surface of the conduit holding portion 16. The guide ridge 20 is inclined at a small angle, for example, 5 to 25 degrees (85 to 65 degrees with respect to the center line) with respect to a plane perpendicular to the axis of the main body 4 so that the upper part is rearward. The tangent of the angle is the lock piece 5
It is preferable that the friction coefficient be smaller than the coefficient of friction between the body and the body 4. The front of the guide ridge 20 is the conduit holding portion 1.
6 are inclined to the side and perpendicular to the rear side. Thereby, when the lock piece 5 is pushed in the axial direction from the rear, the lock piece 5 is locked by the frictional force, and when it rises by the urging force of the spring 6, it slides smoothly. However, in the present invention, the cross-sectional shape of the guide ridge 20 is not particularly limited, and may be rectangular, triangular, arc-shaped, or the like.
Other shapes are also possible. The rear part of the upper end of the guide ridge 20 is notched to accommodate the lower end of the spring 6.

The lock piece 5 is connected to the conduit holding portion 16 of the main body 4.
And left and right side walls 21 arranged on the sides of the top plate, and a top plate 22 connecting their upper ends to each other. A guide groove 23 which slidably fits with the guide ridge 20 is provided on the inner surface of the side wall 21.
Are formed. Locking projections 24 are formed on the left and right inner surfaces of the lower portion of the side wall 21 so as to be engaged with the lower surface of the conduit holding portion 16 when assembled to the main body 4 (see FIG. 3B). The height of the lock piece 5 is such that a gap corresponding to a stroke is formed between the top plate 22 and the conduit holding portion 16 with the locking projection 24 engaged with the lower surface of the conduit holding portion 16 as shown in FIG. . The length of the guide groove 23 is also set to have a gap corresponding to the stroke between the guide groove 23 and the upper end of the guide ridge 20, as shown in FIG. 2B. As shown in FIG. 2B, the rear portion of the guide groove 23 is further extended upward, thereby securing a space for accommodating the upper end of the spring 6. In the present embodiment, a thin step 25 that fits into the opening 12 of the bracket 3 is provided on the back side of the lock piece 5.
(See FIGS. 2a, 2b and 3b). The upper and lower portions of the thin step 25 are cut out so as to smoothly enter the opening in step S3 in FIG.

The internal structure of the main body 4 is basically the same as the conventional one. That is, as shown in FIG.
A space is formed in the inside of the conduit holding portion 16, and the bearing member 26 is accommodated in the space. The end of the casing cap 7 fixed to the end of the conduit 1 is accommodated in front of the bearing member 26 (left side in FIG. 3A), and the spherical end of the guide pipe 8 is rotatable around two axes at the rear. Are provided. The casing cap 7 is made of metal, and includes a cylindrical portion 7a that is caulked around the end of the conduit 1, and a flange portion 7b at the tip thereof. A through hole 7c for passing the inner cable 9 is provided at the center of the flange 7b. Generally, the flange portion 7b is formed in a disk shape, but in the present embodiment, the width of the conduit holding portion 16 is
3b, the flange portion 7b is formed in a disk shape with left and right cutouts as shown by the broken line in FIG. 3B.

In the above-mentioned bearing member 26, the central portion 26a in the longitudinal direction has a large diameter for accommodating the flange 7b, and the front portion 26b and the rear portion serving as the socket 27 have small diameters. Further, in the present embodiment, the left and right sides of the central portion 26a are cut out as shown by broken lines in FIG. Casing cap 7
Front part 26b and socket 27 surrounding the periphery of the cylindrical part 7a
The rear part that constitutes remains cylindrical.

The aforementioned guide pipe 8 has a spherical end 3 at its base end.
The inner cable 9 and a rod 10 connected to an end thereof are accommodated therein so as to be slidable in the axial direction. The inner surface on the rear side of the main body 4 includes an open end to allow rotation of the guide pipe 8 around two axes, that is, swinging motion, including the flange portion 17 and the cylindrical projection 31 for holding the bellows boot. It expands in a tapered shape toward.

The main body 4 is usually formed of a hard synthetic resin, and the guide pipe 8 is formed by outsert molding of a synthetic resin at the end and inner periphery of a metal pipe. After arranging the casing cap 7 and the guide pipe 8 in the main body 4, the bearing portion 26 is formed by injecting a soft synthetic resin, curing the resin, and curing the resin. However, the material of each member and the assembling method are not particularly limited thereto.
It can be manufactured in other ways. The lock piece 5 is also usually formed of a hard synthetic resin, but may be made of another material.

In the mounting structure A configured as described above, the mounting member 2 can be easily mounted on the bracket 3 as shown in step S1 in FIG. That is, first, the top plate 22 of the lock piece 5 is
The lock piece 5 is pressed down with a finger or the like diagonally along the guide ridges 20 against the urging force of. As a result, the gap between the lock piece 5 and the flange portion 12 of the main body 4 increases, and the gap between the front surface of the fitting step 19 and the rear surface of the lock piece 5 becomes wider than the thickness of the bracket 3.

In this state, the front and rear positions are adjusted so that the bracket 3 is located between the fitting step 19 and the lock piece 5, and the insertion portion 18 of the main body 2 is inserted into the notch 1 of the bracket 3.
3, and the lower surface 18a of the insertion portion 18 is brought into contact with the inner peripheral surface of the opening 12 (see step S2 in FIG. 4).

Then, when the finger pressing the lock piece 5 is released, the lock piece 5 is raised obliquely along the guide ridge 20 by the urging force of the spring 6. Thereby, the bracket 3 is sandwiched between the lock piece 5 and the flange portion 17 from the front and rear. In this case, since the lower surface 18a of the insertion portion 18 and the lower surface side of the fitting step 19 are continuous, the fitting step 19 is fitted into the opening 12 naturally. The shallow step 25 of the lock piece 5 is also fitted into the opening 12 (step S3 in FIG. 4). This completes the mounting operation.

As described above, the operation of attaching the main body 2 holding the control cable to the bracket 3 can be performed as easily as the case of the conventional attachment structure or more easily. In this state, since the fitting step 19 having a width larger than that of the notch 13 is fitted to the opening 12, it does not come off to the upper part. Further, the pulling force (leftward force in FIG. 4) applied to the conduit 1 of the control cable is firmly supported by the direct engagement between the bracket 17 and the flange portion 17 of the main body 2. On the other hand, the force in the pushing direction is transmitted to the lock piece by the contact between the guide protrusion 20 and the inclined surfaces of the guide grooves 23 of the lock piece 5. In this case, the axial force is divided into a component force along the inclined surface and a component force perpendicular to the inclined surface, but the component force along the inclined surface is reduced by the wedge action (cam action) of the inclined angle. The spring 6 is sufficiently supported by the urging force of the spring 6 and the frictional force between the inclined surfaces. Conversely, the urging force and the frictional force of the spring 6 increase due to the boosting action of the inclined surface and oppose the axial force. Therefore lock piece 5
Does not move down along the guide ridge 20 and is locked in its original position. Since the lock piece 5 is engaged with the front surface of the bracket 3, the force in the pushing direction of the conduit 1 is firmly supported by the bracket 3.

The friction force on the inclined surface is the product of the component force perpendicular to the inclined surface and the friction coefficient, and increases in proportion to the axial force. Therefore, when the tangent of the angle of the inclined surface is smaller than the coefficient of friction, even if the compressive force applied to the conduit 1 increases, the frictional force increases accordingly, and consequently opposes the axial compressive force. Will be locked. When the coefficient of friction is small and the angle of the inclined surface cannot be made sufficiently small, a spring 6 that generates a sufficiently large urging force may be used.

Next, when disconnecting the control cable from the bracket 3, the procedure is reversed. That is, first, the lock piece 5 is pushed downward against the urging force of the spring 6 from the state of step S3 in FIG. Thereby, the interval between the lock piece 5 and the flange 17 is increased. Next, the mounting member 2 is retracted to some extent, and then the fitting step 19 and the opening 12 are disengaged and pulled upward. Thereafter, when the lock piece 5 is released, the lock piece 5 rises again by the urging force of the spring 6, and the locking projection 24 engages with the lower surface of the main body 4 and stops.

When the mounting structure A is used as described above, not only the mounting is simple, but also the removal is extremely simple, and it is not necessary to use a tool. In addition, since both the work of attachment and the work of removal only require pushing the lock piece 5 from the upper side, the work is easy. Further, since the bracket 3 is sandwiched between the lock piece 5 and the flange portion 17, the accuracy of the thickness of the bracket 3 does not need to be so high.

Next, the mounting structure B shown in FIG. 5 will be described. 5 includes a mounting member 2 and a bracket 3. The bracket 3 is the same as in the embodiment of FIG. The mounting member 2 is a cylindrical main body 4
And a plate-shaped lock piece 5 slidably provided on the outer periphery of a casing cap 7 attached to the main body 4, and for moving the lock piece 5 toward and away from the main body 4 side, and And a link mechanism for maintaining the pressed state. The link mechanism includes a lever 41 rotatably provided on the main body 4, a lock piece 5 and a lever 41.
And a link 42 connecting the middle of the process.

In this embodiment, the lock piece 5 is slidably provided on the casing cap 7, and the lock piece 5 is provided on the front end face 4 of the main body 4.
3 is configured to approach or move away. Therefore, the whole of the main body 4 and the casing cap 7 is the main body of claim 1, the casing cap 7 is an insertion portion, and the front end surface 43 of the main body 4 is a flange portion. An annular fitting step 19 is formed on the front end face 43. It should be noted that the fitting step 19 can also be used as the end of the bearing member 26 shown in FIG. 3A. The inner diameter of the opening 12 of the bracket 3 matches the outer diameter of the fitting step 19, and the width of the notch 13 matches the outer diameter of the casing cap 7 serving as the insertion portion.

The lever 41 is provided with pins 44 on the left and right sides of the main body 4.
The arm 45 includes left and right arms 45 rotatably supported by a lever, and a knob 46 for connecting the free ends of the arms 45 to each other. Each arm 45 is bent forward (left side in FIG. 5) at its free end so that the knob 46 does not interfere with the guide pipe 8 when it is tilted down as in the second step S5 in FIG. . Further, at the rear upper end of the main body 4, an engagement piece 47 that elastically engages with the knob piece 46 of the lever 41 in the state of being tilted to prevent the counterclockwise rotation is protruded.
A leaf spring-shaped clip 48 is attached to the back surface of the lock piece 5 so as to elastically contact the bracket 3. An opening through which the casing cap 7 freely passes is formed at the center of the clip 48.

In the present embodiment, the link 42 is formed by bending a single wire. Basically, each arm 45 of the lever 41 and the side end of the lock piece 5 are connected to each other to substantially form the link. It is formed in a substantially U-shape in plan view from left and right side portions 42a that exert an action and a central portion 42b that connects the ends on the lever 41 side. In addition, the left and right side portions 42a are bent in a substantially U-shape protruding upward in a side view so as to exert the action of a tension spring.
The front end of the side surface portion 42a is bent inward and used as a pin that is rotatably engaged with the lock piece 5.
Also, for the central portion 42b, each arm 4 of the lever 41
5 and the link 42 and the lever 41
The function of a pin for rotatably connecting the pins is achieved. The central portion 42b is curved so as not to interfere with the main body 4 when the lever 41 is tilted as in the second step S5 in FIG.

In the mounting structure B configured as described above, when the lever 41 is turned and raised in the counterclockwise direction as in the first step S4 of FIG. The space between the surface 43 expands. In this state, the casing cap 7 between the lock piece 5 and the body 4
Through the notch 13 of the bracket 3 and positioned at the center of the opening 12. Then, as in the second step S5, the fitting step 19 is fitted into the opening 12 of the bracket 3, and the lever 41 is tilted clockwise. As a result, the link 42 rotates clockwise around the base end (the connection with the lock piece 5) while the distal end (the connection with the lever 41) of the link 42 is pulled backward. As a result, the lock piece 5 is pulled toward the main body 4, and the bracket 3 is sandwiched between the lock piece 5 and the front surface 43 of the main body. Further, in this state, the knob 46 of the lever 41 is elastically engaged with the engagement member 47 at the rear of the main body 4.

After being sandwiched in this manner, the fitting step 19
Are fitted into the opening 12 of the bracket 3, so that they do not come out upward. Further, since the movement of the lock piece 5 toward the main body 4 is restricted, the link 42 is elastically somewhat stretched. Thereby, the lock piece 5 and the front surface 43 of the main body 4 elastically sandwich the bracket 3.

When the lever is turned, the turning angle of the link 42 is smaller than the turning angle of the corresponding lever 41. Therefore, the lever mechanism itself has a boosting action. Further, since the knob 46, which is the point of action of the lever 41, is located outside the connecting portion of the link 42, there is a boosting action by leverage. Therefore, the clamping action of the bracket 3 by the lock piece 5 and the main body 4 is extremely large. When the lever 41 is further lowered, the base end of the link 42, the lever 4
The three points of the center of rotation 1 and the tip of the link 42 are substantially aligned. Therefore, even if a force in the axial direction is applied to the lock piece 5, there is no component force for rotating the link 42, and the engagement between the knob 46 and the engagement piece 47 is provided. Has a large effect of restraining the bracket 3.

When removing the control cable attached to the bracket 3 as described above, the knob 46 of the lever 41 is pulled up, and the engagement between the knob 46 and the engagement member 47 is released. When the lever 41 is further rotated counterclockwise, the distance between the lock piece 5 and the main body 4 is increased. Therefore, after that, the fitting of the fitting step 19 and the opening 12 of the bracket 3 may be released by moving the main body 4 backward, and then the body 4 may be removed.

The clip 48 provided on the back side of the lock piece 5 elastically deforms flat when the bracket 3 is clamped between the lock piece 5 and the main body 4. Therefore, the locking action is maintained by the repulsion action. The repulsive force of the clip 48 is particularly effective when the elasticity of the link 42 or the lever 41 is low.
Conversely, when the elastic deformation of the link 42 or the lever 41 is large to some extent, it is not necessary to provide the clip 48 in particular.

Further, in the embodiment shown in FIG.
Is slidably provided on the casing cap 7, but the lock piece 5 is turned upside down as in the embodiment of FIG.
If it is formed in a letter shape to avoid interference with the casing cap 7, the casing cap 7 can be made free.

In the embodiment shown in FIG. 1, a boosting mechanism is constituted by a cam mechanism formed by fitting the guide ridge 20 and the guide groove 23. In the embodiment shown in FIG. 5, a boosting mechanism is constituted by a link mechanism and a lever. I have. However, the structure of the present invention is not limited thereto, and the lock piece may be urged toward the main body using another boosting mechanism such as a screw. Further, a mechanism for urging the booster mechanism and the lock piece with a cam mechanism or a link mechanism other than the above-described embodiment may be configured. Further, in the above embodiment, the mounting structure is applied to the end of the control cable conduit.
It may be in the middle of the conduit. In addition to the push-pull cable, it can also be used for a pull cable. Further, the conduit may be attached to the main body so as to extend toward the flange.
