Field of industrial application) The present invention relates to a novel vehicle-mounted revolving light. Specifically, it consists of a base fixed to the roof of the vehicle, a glove formed into a cylinder made of transparent material and attached to the base, and a light source, a reflector, etc. that are removably attached to the glove. To provide a novel vehicle-mounted revolving light which is equipped with a unit stand supporting a rotating unit, which facilitates the attachment of a glove to the base and prevents rattling.

(B. Summary of the Invention) The vehicle-mounted revolving light of the present invention has an engaging groove that slidably engages with a horizontal piece provided on the base at the bottom of the globe, and the horizontal piece is formed on the opposite surface of the engaging groove. When the horizontal piece provided on the base is engaged with the engagement groove provided on the glove, the contact relationship between the horizontal piece and the engagement groove is formed on the contact protrusion. By making a point contact through the part, sliding resistance is reduced, making it easier to attach the glove to the base, and also ensuring that the contact protrusion comes into contact with the horizontal piece when putting on the glove. This prevents the glove from rattling against the base.

(C. Prior Art) [Figs. 14 and 15] Conventionally, there is a type of vehicle-mounted revolving light mounted on the roof of a vehicle such as an automobile as shown in Figs. 14 and 15.

b is a base fixed to the roof of a car or the like; c is a glove fixed on the base b; d is a unit base detachably mounted inside the glove c;
A rotating unit e consisting of a light bulb, a reflecting mirror, etc. is supported on the unit stand. f is an outer cover that closes the outer opening of the glove c.

g and g are horizontal pieces projecting inward from both sides of the upper surface of the base b in a substantially horizontal manner; h and h are mounting pieces formed in a rising shape from the side edges of the inner bottom surface of the base A sliding space i is formed between the upper surface of the mounting rib h and the lower surface of the horizontal piece g.

j is a protrusion extending longitudinally from the bottom of the glove c, and engagement grooves k are formed on both side surfaces of the protrusion j.

The glove c is attached to the base b by engaging the horizontal pieces g provided on the base b with the engagement grooves k, k.

(D Problems to be solved by the invention) [Chapter 14
FIG. 15] By the way, the above-mentioned conventional vehicle-mounted revolving light a has the following problems.

That is, the horizontal pieces g, g provided on the base b and the engagement grooves k, k provided on the glove c come into surface contact, and the sliding resistance when joining them is large, causing the glove c to be attached to the base b. There is a problem that it is difficult to attach it to the body.

In addition, if the width of the engagement grooves k is increased in an attempt to make it easier to put on the glove c, play will occur between the horizontal pieces g and the engagement grooves k, and this will cause vibrations during driving. This causes problems such as the glove c becoming loose and causing a malfunction.

(E. Means for Solving Problems) In order to solve the above-mentioned problems, the vehicle-mounted revolving light of the present invention has an engaging groove formed at the bottom of the globe, and an inward groove formed at the side edge of the top surface of the base. A horizontal piece is formed that protrudes to the groove and slidably engages with the engagement groove of the glove, and a contact protrusion that comes into contact with the horizontal piece is formed on the opposite surface of the engagement groove.

Therefore, according to the vehicle-mounted revolving light of the present invention, the contact protrusion is provided on the opposite surface of the engagement groove, so that when the glove is attached to the base, the engagement between the horizontal piece of the base and the glove is prevented. The sliding resistance between the groove and the groove is reduced,
The glove can be easily attached to the base.
