Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to an outside mirror for a vehicle. In particular, the present invention relates to outside mirrors for vehicles used in trucks, pan-type automobiles, etc.

<Prior art and its problems> This type of outside mirror for a vehicle generally places more emphasis on functionality than on external appearance, compared to outside mirrors for passenger cars. For example, the first
In a structure such as the one shown in the figure, the main body a of the back mirror is integrally molded with synthetic resin or the like into an arbitrary shape, and a suitable length is attached to one side of the back mirror itself or attached to it. An arm b which is provided with rigidity capable of withstanding the applied external force is integrally protruded, and a holding piece i which can be swingably held against the support m is installed at the tip of the arm b. ing. The holding part for the support m provided at the tip of the arm b is provided with a notch h in a part of the pipe constituting the support m so that it can be ringed in any shape, and
A holding piece i made of a highly lubricating synthetic resin with i' formed as a part of a spherical surface, a seat c having a hemispherical surface c' formed at the tip of the arm b, and a hemispherical receiving surface on the inner surface.
e′ and connect the machine screw f to the end face d of arm b.
The holding piece i is expanded from the notch h to the center of the hinge l, and presses the inner circumference i'', which is similar to the spherical surface of the outer circumference i, to the support m. Then, a seat c formed at the tip of an arm b integrally provided on the main body a is brought into contact with the holding piece i, and a mounting piece e is mounted from the outside, and a screw provided on the end face d is attached. After aligning the hole d' with the screw hole e'' provided in the mounting piece e, the machine screw f is screwed into the screw hole d' of the end surface d through the washer g, and the main body a is then tightened.
is attached to Support M so that it can swing freely. Naok
is an aperture in main body a, and j is a mirror.

However, in such a conventional example, the holding piece i
is formed in an annular shape, and the notch h cannot be made large because it causes problems in terms of holding force. For this reason, it is not possible to adopt the six mounting methods of mounting the support m from above on the bent support m, and the mounting method is such that the support m is forced to expand from the notch h and the holding piece i is mounted. There was a problem with it being bitter. This is especially true in the case of a large-diameter support m used for a rearview mirror of a large truck, etc., the thickness of the holding piece i itself becomes thick and the rigidity is high, making it increasingly difficult to attach the holding piece i to the support m. . In addition, the holding piece i does not have a positioning structure with respect to the support m, and therefore the holding piece i moves below the support m, worsening visibility conditions.In addition, an extremely strong tightening force is required to prevent the holding piece i from moving. In this case, the strength of the holding piece i and the arm b is greater than necessary, which increases the amount of high-quality materials, resulting in the problem of increased material costs.

<Purpose of the invention> In view of the problems of the conventional example described above, the present invention provides a vehicle having a mounting mechanism that allows easy attachment of the annular holding piece to the support and prevents the main body of the outside mirror from moving downward. The purpose is to provide outside mirrors for
