Description

  The present invention relates to a control cable, and more particularly to a control cable that transmits an operation applied to an operation member of a vehicle to a driven member.

  Generally, the control cable has an inner cable and an outer casing into which the inner cable is inserted. The inner cable has flexibility, one end is connected to the operation member, and the other end is connected to the driven member. That is, the driven member is operated by operating the operating member to operate the inner cable. The outer casing has flexibility, one end is fixed near the operation member, and the other end is fixed near the driven member. In the outer casing, in order to avoid the intermediate portion between one end and the other end from interfering with other members such as the vehicle body, the routing path of the intermediate portion is curved.

  When one end of the inner cable that is inserted into the curved outer casing and is in a curved state is pulled, the inner cable tends to be in a straight state. The force that makes the curved inner cable straight is transmitted to the outer casing as a force that tries to make the curved outer casing straight. Since the outer casing has flexibility, when only the both ends are fixed and the intermediate portion is in a freely movable state, the routing route of the outer casing changes due to the force that makes the inner cable straight. By changing the routing path of the outer casing, the outer casing may interfere with other members such as the vehicle body even if the routing path initially avoids interference with other members.

  A bracket that holds the position of the outer casing is used in order to prevent the routing route of the outer casing from being changed by the force of the inner cable being in a straight state and the outer casing from interfering with other members such as the vehicle body. The bracket has an outer casing fixing portion to which the outer casing is fixed and a vehicle body fixing portion to be attached to the vehicle body. For example, in Patent Document 1, the clip 8 corresponds to the bracket described above. More specifically, the support portion 8c of Patent Literature 1 corresponds to the above-described outer casing fixing portion, and the mounting portion 8a of Patent Literature 1 corresponds to the above-described outer casing fixing portion. A bracket is manufactured from materials, such as a metal and a hard synthetic resin, so that the force which an inner cable tends to become a linear body can be supported. One outer casing is provided with a plurality of brackets having different shapes in order to securely hold the position of the outer casing.

  The bracket is easy to attach to the vehicle body if the bracket is fixed at an angle to the outer casing so that it matches the angle of the bracket with respect to the outer casing when the vehicle body attachment part is attached to the vehicle body. Therefore, it is preferable.

  However, when the bracket is fixed to the outer casing by caulking, it is necessary to set the caulking angle so that the portion other than the portion to be caulked of the bracket and the caulking machine do not come into contact with each other. However, since the angle of the bracket with respect to the outer casing when the vehicle body attachment portion is attached to the vehicle body is different for each bracket, it is complicated to fix the bracket to the outer casing.

  An object of this invention is to provide the control cable provided with the bracket easy to fix to an outer casing.

  The control cable of the present invention includes a main body having an outer casing fixing portion fixed to the outer casing, and a control unit including a plurality of brackets having a vehicle body attachment portion attached to the vehicle body and having an attachment body joined to the main body. It is a cable, Comprising: The main body and the attachment body are comprised so that joining is possible, after fixing the outer casing fixing | fixed part of a main body to an outer casing.

  (1) Since the bracket has a main body and an attachment body, and the attachment body can be joined to the main body after the main body is fixed to the outer casing, the control cable of the present invention has only the main body first. The bracket can be easily fixed to the outer casing.

  (2) When the attachment body has a shape that determines the position of the outer casing relative to the vehicle body for each main body, the shape of the main body can be simplified, and the bracket can be more easily fixed to the outer casing.
