Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting an air cleaner for an internal combustion engine on the internal combustion engine. 2. Description of the Related Art Japanese Patent Laid-Open Publication No. 4-55556 discloses a prior art in which an air cleaner is provided between an internal combustion engine and a throttle body attached to an intake manifold of the internal combustion engine. In addition, it is proposed that the clean side chamber of the air cleaner is mounted so as to communicate with the inside of the throttle body, and is detachably attached to these. In this prior art, the air cleaner is detachably attached to the throttle body by a flange portion integrally provided so as to project outward from the throttle body. In this configuration, the integrally provided flange portion is fastened by bolts. However, when the air cleaner is detachably attached to the throttle body as described above, the mounting flange portion protrudes from the side surfaces of the throttle body and the air cleaner. When narrowing, the flange portion protruding from the side surfaces of the throttle body and the air cleaner as described above not only greatly hinders the narrowing of the engine room, but also a bolt fastening tool is provided at this flange portion. There is a problem that the air cleaner is difficult to enter, and the maintainability of the air cleaner is low. An object of the present invention is to solve these problems. [0005] In order to achieve this technical object, the present invention provides an air cleaner having an upper surface of an internal combustion engine and an upper surface of a throttle body which is mounted on an intake manifold of the internal combustion engine so as to face upward. A clean side chamber of the air cleaner is mounted so as to communicate with the inside of the throttle body, and a lever body rotatably connected to the air cleaner or the throttle body is provided at the tip of the throttle body or the air cleaner. The other end of the clamp body provided with a hook engaged with the engaging portion is moved toward the air cleaner or the throttle body side of the lever body so that the other end of the clamp body approaches the air cleaner or the throttle body. The lever body moves away from the air cleaner or the throttle body. The other end of the clamp body is rotatably connected so as to move away from the air cleaner or the throttle body. "
It was configured to say. In this configuration, the air cleaner is mounted between the upper surface of the internal combustion engine and the upper surface of the throttle body, and in this state, the air cleaner is pivotally mounted on the air cleaner or the throttle body. By rotating the lever body once away from the air cleaner or throttle body,
After the hook at the tip of the clamp body rotatably connected to the lever body is engaged with the engagement portion provided on the throttle body or the air cleaner, the lever body is rotated toward the air cleaner or the throttle body. . [0007] Then, the other end of the clamp body moves closer to the air cleaner or the throttle body by the rotation of the lever body toward the air cleaner or the throttle body, so that the air cleaner can be fastened to the throttle body. It is. Further, the other end of the clamp body moves away from the air cleaner or the throttle body by rotating the lever body in the opposite direction, that is, on the side away from the air cleaner or the throttle body. Can be released. That is, according to the present invention, the air cleaner is attached to or released from the throttle body by rotating the lever body.
Compared with the conventional method in which an outwardly protruding flange portion is bolted, mounting and dismounting can be performed more easily, and the size of the protrusion from the air cleaner and the throttle body can be reduced. Without lowering the maintainability of
This has the effect that the engine room can be narrowed. An embodiment of the present invention will be described below with reference to FIGS. In this figure, reference numeral 1 denotes an internal combustion engine, reference numeral 2 denotes a throttle body mounted upward on an intake manifold (not shown) mounted on a side surface of the internal combustion engine 1, and reference numeral 3 denotes the internal combustion engine. 1 shows an air cleaner for each. The air cleaner 3 is mounted between the upper surface of the internal combustion engine 1 and the upper surface of the throttle body 2 such that the clean side chamber 3a of the air cleaner 3 communicates with the inside of the throttle body 2. ing. In this case, the portion of the air cleaner 3 that rides on the upper surface of the internal combustion engine 1 is detachably attached to the internal combustion engine 1 with bolts 5 inserted through grommets 4 made of a soft elastic body. . When attaching and connecting the air cleaner 3 to the throttle body 2 with a gasket 6 interposed therebetween, a spring wire is formed in a U-shape on the outer surface of the air cleaner 3. The base end of the lever body 7 is rotatably pivoted, and a loop part 7a is provided in the middle part of the lever body 7, while an engaging part 8 is integrally formed on the outer surface of the throttle body 2. And the other end of a clamp body 9 formed by bending a spring wire into a U-shape so as to provide a hook 9a for engaging with the engaging portion 8 at the end thereof, with respect to a loop portion 7a of the lever body 7. The air cleaner 3 indicated by the solid arrow A of the lever body 7
The other end of the clamp body 9 moves closer to the air cleaner 3 by turning to the side, and the other end of the clamp body 9 turns to the air cleaner by turning the lever body 7 away from the air cleaner 3 indicated by the dotted arrow B. 3 so as to be rotatable apart from each other. In this configuration, the air cleaner 3 is mounted between the upper surface of the internal combustion engine 1 and the upper surface of the throttle body 2, and in this state, the lever 7 pivotally attached to the air cleaner 3 is once rotatably mounted. By pivoting away from the air cleaner 3, the hook 9 a at the tip of the clamp body 9 rotatably connected to the lever body 7 is engaged with the engaging portion 8 provided on the throttle body 2. Thereafter, the lever body 7 is turned toward the air cleaner 3 as shown by a solid arrow A. Then, the other end of the clamp body 9 moves closer to the air cleaner 3 by the rotation of the lever body 7 toward the air cleaner 3, so that the air cleaner 3 is moved to the throttle body 2 as shown in FIG. It can be concluded. In this mounting state, the lever body 7 is configured not to return and rotate by exceeding a so-called dead point with respect to a pivot point with respect to the air cleaner 3. The other end of the clamp body 9 moves away from the air cleaner 3 by rotating the lever body 7 in the opposite direction indicated by the dotted arrow B, that is, in the direction away from the air cleaner 3. , The throttle body 2
Can be released from the air cleaner 3.
In the above embodiment, the lever body 7 with the clamp body 9 is provided for the air cleaner 3 and the engagement part 8 for the hook 9a at the tip of the clamp body 9 is provided for the throttle body 2. The present invention is not limited to this, and the lever body 7 with the clamp body 9 is
It is needless to say that a configuration in which the air cleaner 3 is provided in the air cleaner 3 may be adopted.
