TRANSMISSION MECHANISM, RAISING DEVICE, AND INSERTING APPARATUS

摘要

A transmission mechanism includes a pulling and pressing member including a distal end portion coupled with a raising stand and a proximal end portion coupled with a raising operation unit and a containing portion containing the pulling and pressing member with the distal end portion of the pulling and pressing member projecting therefrom. The transmission mechanism further includes an elastic member that the distal end portion side of the pulling and pressing member projecting from the containing portion is inserted into the cylindrical elastic member.

主权项

1. A transmission mechanism coupled to a raising stand that rotates and a raising operation unit operating the raising stand, and transmitting an operating force of the raising operation unit to the raising stand, comprising:
a pulling and pressing member including a distal end portion coupled with the raising stand and a proximal end portion coupled with the raising operation unit, and pulling or pressing the raising stand by an operation of the raising operation unit to rotate the raising stand; a containing portion containing the pulling and pressing member with the distal end portion of the pulling and pressing member projecting therefrom; and a cylindrical elastic member including a proximal end portion connected in a watertight state to the containing portion, and expanding and contracting, and covering the pulling and pressing member projecting from the containing portion in a watertight state.
