As disclosed in Japanese Unexamined Patent Publication No. 17 (F16J15 / 08), a cylinder head for an internal combustion engine has a gasket made of a soft metal arranged in a groove formed in the head. Many of these seal members are ring-shaped, and in the case of a ring-shaped seal member, they can be mounted on the head by adsorbing them from a magazine with a cylindrical adsorbing device and then transferring them to the annular groove of the cylinder block.

[0003]

As described above, in the conventional case where the seal member is a simple ring shape, the suction member can mechanically set the seal member in the groove, but in recent years, the shape of the cylinder head or the seal has been improved. Along with the diversification of the shape of the groove as a part, the sealing member has come to be formed into various shapes. In addition, since the seal member is thin, its surface area is very small, and it is soft, it cannot be mechanically grasped or adsorbed and transferred by a conventional operator when the shape is complicated, and the operator manually Therefore, there is a problem that the workability is poor because it has to be set in the groove.

The present invention has been made in view of the above points,
An object of the present invention is to provide a seal member mounting device having excellent workability, which allows the suction device to automatically mount the seal member to the seal portion without manual work of the operator even when the seal member has a complicated shape.
