A timing pulley comprising:
- a cylindrical timing hub which is fitted around a power transmitting shaft;
- a pair of flange members provided apart on both end portions of said timing hub, and
- a plurality of engagement pins disposed on peripheral edge portions of said pair of flange members in a circumferential direction thereof so as to extend between and through each of said flange members and so as to engage with mating teeth of a timing belt.
A motion transmitting mechanism comprising:
- a power transmitting shaft;
- a timing belt including a plurality of mating teeth;
- and
- a timing pulley including:
- a cylindrical timing hub which is fitted around the power transmitting shaft;
- a pair of flange members provided at both end portions of said timing hub having a cylindrical shape, and
- a plurality of engagement pins disposed along an outer circumference of the said pair of flange members, the engagement pins being disposed in a space between the said flange members and being adapted so as to extend through an inserting hole of each of said flange members, the engagement pins engaging with the mating teeth of a timing belt as the timing pulley is driven as the power transmitting shaft is rotated.
