Three fragile arms 26b extending outward in the radial direction into three equal parts
An annular portion 26c is formed at the distal end of the fragile arm portion 26b to be connected to each other in an annular manner. Note that each of these fragile arm portions 26b is formed to be curved downward so that it can be plastically deformed at this location. In addition, the annular portion 2
6C, the spoke part core metal 24 is made of aluminum and the annular part 26c is made of steel, and since it is difficult to connect the two using welding, an annular contact plate made of steel or the like is installed at the predetermined position of 6C. 27, and an insertion hole 26d is bored therein so as to be able to connect with a fixing means 28 such as a rivet or bolt. Of course, if the spoke core metal 24 is made of steel, it can be welded, so the contact plate 27 and the insertion hole 26d are not necessary. Incidentally, regarding the connection between the connecting body 26 and the spoke core 24, the spoke core 24 has a T-shaped shape on the boss 22 side, and the T-shaped portion 24a has an annular shape in the connector 26. An insertion hole 24b is formed corresponding to the insertion hole 26d of the portion 26c, and the one-shaped portion 24a of the spoke portion mandrel 24 and the contact plate 27 are sequentially arranged on the connecting body 26, and the fixing means 2, such as a rivet, are arranged.
8 to secure both names. Note that the connection between the connecting body 26 and the boss portion 22 is performed using welding. Further, 29 is a plate material that fills the gap between the connecting body 26 and the contact plate 27 where the spoke core metal 24 is not arranged.

。In the steering wheel mandrel 21 formed in this way, a plastically deformable connecting body 26 is disposed between the boss part 22 and the spoke part mandrel 24, and an impact force is applied to the ring part mandrel 23. However, the impact energy is transferred to the connecting body 26.
Since the connecting part 2 absorbs by plastic deformation,
Even if the steering wheel core 1 of the first to third embodiments is made of die-cast metal with low elongation, the connecting portion 25 can be prevented from cracking.
・In 11.21, the number of fragile arms 6b, 16b, 26b formed in the connecting bodies 6, 16 and 26 was shown as three and five, but of course, The number and shape are not limited to these embodiments as long as they can be plastically deformed so as not to cause 11A warpage.
