Cam gear driving apparatus of a video cassette recorder

A cam gear driving apparatus of a video cassette recorder comprising:

• a driving source for generating power, said driving source having a driving shaft which has a plurality of protrusions at a position adjacent to a distal end thereof;
• a supporting means for supporting said driving source, said support means being attached at one end thereof to a base and being connected at an other end thereof with a cam gear shaft of a cam gear, said driving shaft of said driving source extending through said supporting means;
• a driving gear for rotating said cam gear, said driving gear being rotatably supported by a boss mounted in said base;
• and
• a means for transmitting power generated by said driving source from said driving source to said driving gear, said power transmitting means includes a guide member mounted on and fixed to said driving shaft of said driving source, a rotating disc connected to said protrusions of said driving shaft in order to move along said driving shaft, an elastic member disposed between said guide member and said rotating disc, wherein said driving shaft extends through said elastic member, a first friction member attached to a bottom surface of said rotating disc, and a second friction member attached to an upper surface of said driving gear and being in contact with said first friction member.
