  However, since the cover unit of the handrail device in the above-described conventional example needs to be formed in advance according to the shape of the bracket, it is necessary to set a plurality of types of cover units that match the shape of the bracket. This increases the cost of the entire device.

  In addition, the cover alone needs to have a certain hardness in order to ensure shape retention, but as a result, there is a problem in that the shock absorption ability in the mounting state on the bracket is lowered.

  The present invention has been made in order to eliminate the above-mentioned drawbacks, and is intended to reduce the cost by increasing the versatility of the bracket cover, and to improve the safety of the shock by increasing the shock absorption capacity at the time of contact with the bracket. An object is to provide an improved handrail device.

  Another object of the present invention is to provide a handrail bracket cover that can be used in the handrail device.
