To surely notify an incoming call without disturbing surrounding people by the incoming call of a portable telephone set in a briefcase by incorporating a vibrator, which vibrates by receiving radio waves emitted by the portable telephone set at the time of an incoming call, in the hollow part of a handle.

The handle 1 is constituted of an aluminum upper die 10 and a lower die 11 made of hard resin and the vibrator is housed on the lower die 11. A substrate unit 20 is a plate-like matter consisting of metal and hard synthetic resin and transmits vibration generated by the rotation of a motor for generating vibration 21 to the handle 1. The motor 21 is fixed with an eccentric plate 21b to its output axis 21a and generates vibration by the plate 21b rotated in one body with the axis 21a. A dry cell 22 to use is on the market. An ON/OFF switch 23 projects from the lower surface of the die 11 so as to prevent its operation part from being very conspicuous. The motor 21 is rotated only when the switch 23 is in an ON state and the radio waves emitted by the portable telephone set at the time of call incoming is received.
