In particular, the present invention relates to an outside mirror for a vehicle, which includes a spherical holder which rotatably pivots the mirror body to the tip of the support, and is fitted and fixed to the tip of the support.

<Prior art and its problems> In general, this type of vehicle outside mirror has been more focused on functionality than on external appearance, compared to outside mirrors for passenger cars. For example, the first
In the structure shown in the figure, as shown in Japanese Utility Model Publication No. 58-51077, 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 in the longitudinal direction of the back mirror itself or Arm b with rigidity capable of withstanding external forces acting on it
is integrally protruded, and a support m is provided at the tip of the arm b.
A holding piece i which can be held swingably relative to the holding piece i is provided inside and attached to the holding piece i. and arm b
The holding part for the support m provided at the tip of is
A holding piece i made of a synthetic resin with high lubricity and having a notch h formed on the outer periphery of the pipe constituting the support m so that it can be ringed in any shape, and the outer periphery i′ formed as a part of a spherical surface. , a catch c having a hemispherical surface c' formed at the tip of the arm b, and a machine screw f having an inner surface formed with a hemispherical receiving surface e' to the end face d of the arm b.
The holding piece i is expanded from the notch h to the center of the hinge l, and is attached to the support m so that the inner circumference i'', which is similar to the spherical surface of the outer circumference i, is brought into pressure contact with the support m. Then, a seat c formed at the tip of an arm b integrally projecting from the main body a is brought into contact with the holding piece i, and a mounting piece e is covered from the outside, and a screw hole d' formed in the end face d is connected to the holding piece i. After matching the screw hole e″ provided in the mounting piece e, insert the machine screw f through the washer g into the screw hole in the end face d.
By screwing and tightening d', the main body a is attached to the support m so that it can swing freely. Note that the opening j of the main body a is a mirror k.

Furthermore, in this example, the spherical holding piece i is supported m
Since the mirror body a' is provided in the middle of the support m', it cannot be used in a structure in which the mirror body a' is attached to the tip of the support m' as shown in FIG.

Therefore, in these conventional examples, the holding piece i
Since it is a separate piece that is divided into two pieces, the catch c and the mounting piece e, which support the pivot, the fixed part that fixes the catch c and the mounting piece e is exposed, and the external tightening part is exposed. There have been cases where problems have occurred when adjusting the tightening due to dirt or grime in that area. Furthermore, since the holding piece i is held oppositely by the seat c of the arm m divided into two and the mounting piece e, it is not suitable for a configuration in which the main body of the mirror is attached to the tip of the support.

<Purpose of the invention> In view of the above-mentioned problems of the conventional example, the present invention is designed to facilitate attachment of the sphere holder to the support and prevent the mirror body from moving downward at the end of the outside mirror body. An object of the present invention is to provide a vehicle outside mirror having a mounting mechanism.

<Structure of the invention> In order to achieve the above object, the outside mirror for a vehicle of the invention includes a support pivotally supported on the vehicle body, a spherical holder attached to the tip of the support, and a spherical holder attached to the support. The spherical holder has a mirror body which is rotatably held at the tip of the support through the support, and the spherical holder has an elastic engagement piece formed on the periphery of the opening and a fitting protrusion protruding from the bottom surface of the support. An insertion hole is formed in a recess, and the insertion hole is press-fitted into the tip of a support, and the protrusion is fitted into the opening of the support, so that the elastic engagement piece is engaged with a fitting recess formed in the support. It is characterized by being fixed to the tip of the support by.
