PROBLEM TO BE SOLVED: To provide an electronic pen in which, a shaft member hardly rotates.SOLUTION: An electronic pen comprises a shaft member 2, a coil spring 50, and a gear mechanism in a housing. The housing extends in an axial direction. The shaft member 2 extends in the axial direction and has a pen tip in a first direction side. The coil spring 50 is disposed around the shaft member 2, and energizes the shaft member 2 in a second direction opposite to the first direction. The gear mechanism is disposed on the second direction side of the shaft member 2. The gear mechanism moves the shaft member 2 in the axial direction, for taking the pen tip in and out between inside and outside of the housing. A first gear member disposed on the gear mechanism contacts an end part of the shaft member 2 in the second direction. The first gear member rotates in a peripheral direction when the gear mechanism takes in and out the pen tip between inside and outside of the housing. A shaft projection part 200 projects from the surrounding of the shaft member 2. The shaft projection part 200 contacts an end part 501 of the coil spring 50 in the second direction side, in the peripheral direction.SELECTED DRAWING: Figure 22 |
