<P>PROBLEM TO BE SOLVED: To provide a new configuration that holds lubricity between a shaft and a shaft hole in a driven gear or the like rotated by receiving a driving force from a driving gear. <P>SOLUTION: A gear mechanism includes a slide-contact part 44D configured such that a shaft 42A and a shaft hole 44B are brought into sliding contact with each other when a driven gear 42 is rotated by receiving a driving force from a driving gear 41. The slide-contact part is provided with a groove 44E filled with a lubricant for lubricating the slide-contact part 44D. By this, it allows a lubricant to be supplied to the slide-contact part 44D where a contact surface pressure is increased. Consequently, it is possible to provide a new configuration that holds lubricity between the shaft 42A and the shaft hole 44B. <P>COPYRIGHT: (C)2011,JPO&INPIT |
