Abstract

PROBLEM TO BE SOLVED: To prevent intrusion of mud and dust from connected parts in a device where an intake outlet projection protruding from an air flow meter is connected to an intake inlet recess opened in an air cleaner by attaching a seal member with an insertion length restriction means to the projection of the air flow meter. SOLUTION: Air taken in from an outside air intake port is measured in its amount of flow after dust or foreign matter is removed by an air element in an air cleaner 2 and the air is supplied into an internal combustion engine. Connected parts of the air cleaner 2 and the air flow meter 4 comprises a recess 2a formed in an air cleaner 2, a projection 4a protruding from the air flow meter 4, and a flanged seal member 3. The seal member 3 has several grooves on the outer periphery of a short cylindrical part which is a lip. With this constitution, it is possible to prevent generation of abnormal sound or wear at the time when connected parts 2a, 4a are brought into slidable contact with each other by vibration generating during operation of an internal combusition engine.

However, as shown in FIGS. 3 and 4, the start-up of the internal combustion engine E can be achieved only by joining the convex portion 4a of the air flow meter 4 to the concave portion 2a of the air cleaner 2. When the concave portion 2a and the convex portion 4a come into contact with each other due to vibrations generated during operation or during operation, it causes abnormal noise and wear. Further, the internal combustion engine room is constantly exposed to mud and dust during traveling, and if these enter, the function of the air cleaner 2 cannot be sufficiently exhibited. Although the flange 2a for regulating the insertion length of the projection 4a is provided on the air cleaner 2, the insertion length of the projection 4a cannot be clearly confirmed.
Depending on the operator, there is a possibility that the screw will be screwed into force.

Here, the seal member 3 is made of synthetic resin.
The flange portion 3a has a substantially short cylindrical shape, and a flange portion 3a whose outer shape is slightly larger than the short cylindrical portion is formed on one side. In addition, several grooves are provided on the outer periphery of the short cylindrical portion, and the outer periphery of the short cylindrical portion has a lip shape. The air cleaner 2 and the air flow meter 4 are joined by inserting the convex portion 4a of the air flow meter 4 from the flange portion 3a side of the seal member 3,
This is performed by inserting the convex portion 4a on which the seal member 3 is mounted into the concave portion 2a provided on one side inside the air cleaner 2. Also, at the time of joining, the flange portion 3a comes into contact with the cylindrical end of the intake port of the air cleaner, so that the amount of insertion of the air flow meter 4 into the air cleaner 2 is restricted, which is more than necessary. It is not inserted and its state is visible. Further, the fold shape of the outer periphery of the short cylindrical portion is inclined in the direction of the flange portion 3a, so that it can be inserted relatively easily at the time of joining, but has a shape that is difficult to be pulled out in the opposite direction, so that the air cleaner 2 and the air flow -Can be securely joined to the heater 4.

According to the present invention, the convex portion of the air flow meter is provided with:
Since the seal member provided with the insertion length regulating means is mounted and joined to the concave portion of the air cleaner, the air cleaner and the air flow meter slide due to vibration generated at the time of starting or operating the internal combustion engine. The generation of abnormal noise and abrasion due to the fitting are eliminated, and the joint between the concave portion of the air cleaner and the convex portion of the air flow meter is sealed, thereby preventing intrusion of dust and dust. Further, by providing the insertion length regulating means on the seal member, the abutting portion becomes visible when the convex portion of the air flow meter is inserted, so that the worker can easily confirm the abutting. Further, since the flange portion is provided, it is possible to prevent the seal member from coming into the air cleaner and falling off due to the negative pressure of the intake air from the air cleaner side.
