Abstract

PURPOSE:To extend antenna elements slowly by providing a resistance granting member giving resistance to a pinion which engages a rack between the pinion and an antenna holder which is energized by a spring member. CONSTITUTION:When a user operates an operation button 13, its engagement claw part 13a comes out of an engagement part 5d of an antenna holder 5. Then the antenna holder 5 begins to move up with the spring force of a spring member 7. At this time, a pinion 8 which engages a rack 9 is to rotate, but directly receives the spring force of the spring member 7 as it is and does not rotate, so that the pinion rotates while receiving the resistance force of a resistance grating member 10. In this case, the spring force of the spring member, the clamping extent of a pivot pin, etc., are brought into consideration for the rotary torque of the pinion, not to mention the resistance force. Therefore, an antenna element 6 slowly moves down out of an antenna storage case 2 and stops at a specific position.

Then, when the user operates the operation button 13, the engaging claw portion 13a is disengaged from the engaging portion 5d of the antenna holder 5. Then, the antenna holder 5 starts to move up due to the spring force of the spring member 7. At this time, the pinion 8 meshing with the rack 9 rotates, but does not directly receive the spring force of the spring member 7 and does not rotate, but rotates while receiving the resistance force of the resistance applying member 10. In this case, the rotation torque of the pinion 8 takes into consideration not only the resistance force of the resistance applying member 10 but also the spring force of the spring member, the degree of tightening of the pivot pin, and the like. Therefore, the antenna element 6 slowly moves up and down from the inside of the antenna housing case 2 and stops at a predetermined position.
