摘要： An insertion assisting device includes a rotary body formed in a toroidal shape, and a support and drive unit that rotatably supports and rotates the rotary body. The support and drive unit has two supports, a first support and a second support. The first support is formed in a substantially cylindrical shape, and rotatably supports the rotary body. The second support is formed in a substantially triangular tubular shape, is arranged inside the first support, and supports driving gears that transmit a driving force to the rotary body. The second support is shorter than the first support, and is arranged so that front and rear end portions thereof are located inside front and rear end portions of the first support.

摘要： A self-propelled device includes a mounting part mounted on an insertion part of an endoscope, a hollow toroidal rotary body, and a rotary body supporting tube that is arranged in the internal space of rotary body and supports the rotary body from the inside. The rotary body supporting tube is attached to the outside of the mounting part. The mounting part is provided with a worm wheel, and the rotary body supporting tube is provided with a driven roller. The rotary body is sandwiched between the worm wheel and the driven roller, and is circulated and moved with the rotation of the worm wheel. Wipers for closing the gap formed between the mounting part and the rotary body are provided at the front and rear ends of the mounting part, and thereby preventing entering of foreign body from the gap.
