Description

  The present invention relates to a motorcycle including first and second linear members, such as a hydraulic hose and a wire harness, one end of which is connected to an engine mounted on a body frame, and more specifically, the linear member. It relates to the improvement of the fixed structure.

  In a motorcycle, for example, the temperature and pressure of engine lubricating oil are detected by a sensor, and the detected data is transmitted to a control unit via a wire harness or the like, and the engine operating state and each actuator are controlled by the control unit. It may be configured as follows.

  When wiring such a wire harness or the like, if the wire harness or the like is relatively long, it is common to fix the midway portion with a clamp or the like.

As this type of clamp structure, there is disclosed a structure in which an elastic holding portion constituting a holding recess is formed so that one side and the other side locking projections are stepped up and down (for example, see Patent Document 1). .
Japanese Patent Publication No. 3497105

  By the way, the conventional structure described in the above-mentioned conventional publication is based on the premise of fixing a so-called self-supporting cable in which the cable main body portion and the support wire portion are integrally formed, so that the two linear members are separated. If it is, there is a problem that it cannot be adopted.

  Further, in the above clamp structure, the clamp is separate from the attached member to which the cable is attached. Therefore, a structure for fixing the clamp to the attached member is necessary, and the structure is complicated and the number of parts is reduced. Increase problems are likely to occur.

  The present invention has been made in view of the above-described conventional problems. The first and second linear members configured separately can be clamped with a simple structure, a small number of parts, and high workability. It is an object to provide a motorcycle having a structure.

The present invention is a motorcycle comprising a body frame, an engine mounted on the body frame, and a first linear member and a second linear member having one end connected to the engine, A cover member is detachably attached to the side wall of the engine, and a clamp portion is formed on the cover member. The clamp portion includes a first support portion that supports the first linear member, and the second wire. And a second support part for supporting the shaped member.

  According to the present invention, since the first support part for supporting the first linear member and the second support part for supporting the second linear member are integrally formed in one clamp part, they are formed separately and independently. The first and second linear members can be simultaneously supported by one clamp portion. In this case, for example, the work of binding the first and second linear members with a wire or the like is unnecessary, so that the fixing workability of the first and second linear members can be improved.

  Further, since the clamp part is integrally formed with the cover member, a structure and work for fixing the clamp part to the member to be attached are unnecessary, so that the structure can be simplified and the fixing workability of the linear member can be improved.

  Furthermore, since the clamp part is integrally formed with a cover member that is detachably mounted on the engine side wall, the manufacture of the clamp part is easier than when the clamp part is directly formed on the engine side wall. If the clamp part is damaged due to a fall or the like, only the cover member with the clamp part needs to be replaced, and the repair cost can be reduced.
