2. Description of the Related Art In recent years, mountain bike type bicycles and bicycles referred to as city cycles have become popular as multi-purpose bicycles, and as these bicycles become more widespread, their running performance is improved as shown in FIG. In addition, adoption of a so-called straight type handle 3 which is linear with respect to the frame 1,
In conjunction with this, the straight front fork 2 has been frequently used. However, although the running performance of the bicycle has certainly been improved by adopting such a straight front fork 2 and the straight type handle 3, vibrations caused by pebbles and irregularities on the road surface during running are reduced by the occupant's handle grip 4. It became easier to directly reach the palm holding the arm and the arm in an extended state, which was extremely discomforting. For this reason, in order to reduce the direct vibration to the body of this type of handle, various measures have been taken to reduce the vibration of the handle grip.

[0003] As this kind of prior art, for example, one described in Japanese Utility Model Publication No. 48-34376 and Japanese Utility Model Publication No.
There is one described in Japanese Patent Application Laid-Open No. 4-27717. In the former conventional example shown in FIG. 9, the handlebar end 5B
In addition, a vibration isolating grip main body 7 made of a rubber-like elastic body having a space is attached thereto, and the vibration transmitted to the hand from the vibration source is effectively attenuated. However, as a bicycle handle grip commonly used by men and women of all ages, the anti-vibration grip body 7 made of a rubber-like elastic body having the above-mentioned space is still inappropriate in gripping condition and shape in thickness and the like. It was hard to say.

Further, in the latter conventional example shown in FIG. 10, a handle grip body 7 integrally formed of an elastic material having a low foam inside and a high foam outside is provided on the end 5B of the handle bar 5A. Is attached to prevent vibration to the hand. However, even in this example, it is difficult to obtain a uniform foaming state and sufficient strength and hardness of the skin as set.
