PROBLEM TO BE SOLVED: To provide a connection gear capable of being thin-walled and miniaturized and exhibiting diversification. SOLUTION: The connection gear is provided with a connection gear main body 2 and a fixing member 4 fixed on a strap member 3 and detachably retained in the main body 2. A cam floor 21 is provided on the fixing member 4. A heart cam groove 8 engaging with the cam floor 21 to guide it is formed on the main body 2. Elastic members 10a and 10b are provided on the main body 2 for energizing the fixing member 4 so that the elastic members 10a and 10b are pressed by the fixing member 4 to be elastically deformed when the cam floor 21 is shifted from an engagement start position of the groove 8 to a retaining position and elastically return to energize the fixing member 4 when shifted from the retaining position to the engagement start position. Ends of the elastic members 10a and 10b are shiftably retained in a retaining groove 9 formed on the main body 2. The retaining groove 9 extends in a direction where a space between both ends of the elastic members 10a and 10b is shifted. COPYRIGHT: (C)2007,JPO&INPIT
