Claim:
1. Endoscopic insertion device for inserting into a body lumen, the insertion body comprising: a base having a distal portion, a proximal portion, a hollow space and an opening which communicates with the hollow space; a tube having a channel configured to receive a drive shaft, wherein a distal portion of the tube is connected to the base so as to communicate with the opening; a guide rotatably attached to the base about a pivot axis perpendicular to a central axis of the base, the central axis extending from the distal portion of the base to the proximal portion of the base, the guide being configured to hold a distal portion of the drive shaft inserted into the channel, the guide being rotatable about the pivot axis between a first position arranging the distal portion of the drive shaft in the hollow space and a second position arranging the distal portion of the drive shaft outside the hollow space; and an annular rotating body configured to rotate around the central axis in response to receiving rotation from the drive shaft when the drive shaft is supported by the guide arranged in the first position, wherein the guide inclines a longitudinal axis of the distal portion of the drive shaft with respect to the central axis of the base when the guide is in the second position.
