Abstract
An electronic component of this invention having a fine adjustment mechanism is applicable to a variable resistor, variable capacitor or the like which requires fine adjustment. In this electronic component; a drive shaft having an eccentric cam formed thereon is provided. A ring-shaped intermediate reduction member having a power transmitting portion formed on its outer periphery is fitted into the eccentric cam of the drive shaft. The intermediate reduction member is constructed so that it cannot be rotated but is allowed to make an eccentric movement. A reduction rotating member is provided which has a power transmitting portion formed on its inner periphery, linked to a portion of the power transmitting portion of the intermediate reduction member and has a diameter different than that of the intermediate reduction member. An actuating member of the electronic component is coupled to the reduction rotating member. This electronic component can be provided which is small in size, requires a small number of parts and can provide a large reduction ratio and smooth operation despite use of gears while eliminating backlash.
