The arm member is arranged to be fitted onto the outer circumference of the front tube part in such a way as to embrace it with the claws engaging the piercing holes. The claws are arranged to enter and engage the annular groove when the front tube part is fitted onto the stem.
What is claimed is: 1. An assembly comprising a speedometer, a flexible shaft, and a device for connecting said flexible shaft to said speedometer, said speedometer including an axially extending stem with an outer circumferential surface, an annular groove formed in and extending around said circumferential surface, a rotating shaft extending through said stem, said flexible shaft includes an axially extending inner shaft, said inner shaft is coupled to and rotates said rotating shaft, said device comprises a connecting tube formed of a synthetic resin, said connecting tube includes a front tube part positioned around said stem, said front tube part having a pair of diametrically opposite piercing holes, a rear tube part positioned around said flexible shaft, said front tube part having a larger diameter than said rear tube part, and a tapered tube part extending between and interconnecting said front and rear tube parts with the axes of said front, tapered, and rear tube parts disposed in axial alignment, a lever formed integrally with said connecting tube at the location of the connection of said tapered tube part to said front tube part, said lever connected to said connecting tube by a thin walled hinge part and said lever being pivotally displaceable between a first position standing upwardly from said connecting tube and a second position pivoted downwardly toward and extending in the axial direction of said front tube part, a U-shaped arm extending transversely of and formed integrally with said lever at a location between the opposite ends of said arm, the opposite ends of said U-shaped arm being elastically deformable toward and away from one another, each of said opposite ends has a claw extending toward said claw on the other said opposite end, said U-shaped arm is dimensioned to fit around said front tube part and is displaceable with said lever from the first position where it is spaced from said front tube part into the second position where it fits partly around the outside surface of said front part and initially said claws deform outwardly away from one another and then said claws engage into said piercing holes with the inner ends of said claws engaging into said annular groove formed in the circumferential surface of said stem when said front tube part fits over said stem.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring to the accompanying drawings FIGS. 1, 2 and 3 which show the first example of embodiment of the invention, a connecting device 1 is adapted for connecting the stem 6 of an eddy current type speedometer 2 to one end of a flexible shaft 11. The connecting device 1 as a whole is composed of a connecting tube 3 which is made of a synthetic resin material. The connecting tube 3 consists of a front tube part 10 and a rear tube part 9. The two tube parts 10 and 9 are connected to each other by a tapered tube part 19 with their axes in alignment. The front tube part 10 is fitted onto the stem 6 of the speedometer 2. Meanwhile, the rear tube part 9 is arranged to be fitted onto and welded to one end of an outer tube 12 of the flexible shaft 11.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an oblique view showing the essential parts of the connecting device of the present invention as a first example of embodiment thereof.
SUMMARY OF THE INVENTION It is therefore a general object of the present invention to provide a device for connecting a speedometer to a flexible shaft which eliminates the above stated drawbacks of the conventional connecting device. The connecting device according to the present invention enables to connect a speedometer to a flexible shaft easily and reliably and enables to perform disconnecting work also easily and quickly. Further, the invented connecting device is economical because it has a lesser number of parts required than the conventional device.
