## Abstract

An advancing/retreating movement mechanism 1 of an advancing/retreating member includes: a lifter 3; a coil spring 5; a lock pin 7 that limits the movement of the lifter 3; a case 2 that accommodates the lifter 3 and the coil spring 5; an advance/retreat position control mechanism 9 that controls an advance position, a retreat position, and a reciprocating movement of the lifter 3; and a receiving seat 11 that receives the coil spring 5 so that the lifter 3 is biased. The receiving seat 11 is arranged in a rearward position side of the lifter 3. An engaging part 27a engaging the lock pin 7 is arranged to the lifter 3. When the lifter 3 moves to the retreat position, the engaging part 27a moves to a rearward side beyond the receiving seat 11 and moves to a position where the engaging part 27a can be engaged with the lock pin 7. Therefore, the size of the advancing/retreating member in a protruding/withdrawing direction can be made small.

## Claims

### Claim 1

An advancing/retreating movement device comprising:
an advancing/retreating member;
an biasing member;
a limiting member that limits a movement of the advancing/retreating member;
a case that accommodates the advancing/retreating member and the biasing member;
an advance/retreat position control mechanism that controls an advance position, a retreat position, and a reciprocating movement of the advancing/retreating member, wherein the advance/retreat position control mechanism comprises a restricting part that restricts a movement of advance/retreat of the advancing/retreating member and a cam part, which guides the restricting part and further suppresses backlash during the advance/retreat movement of the advancing/retreating member; and
a receiving seat that receives the biasing member so as to bias the advancing/retreating member, wherein
the receiving seat is arranged at a rearward position side of the advancing/retreating member,
an engaging part that engages with the limiting member is arranged at the advancing/retreating member, the engaging part moves to a rearward side beyond the receiving seat when the advancing/retreating member moves to the retreat position and further moves to a position where the advancing/retreating member can be engaged with the limiting member.

### Claim 2 (depends on 1)

The advancing/retreating movement device according to claim 1, wherein
the advance/retreat position control mechanism is arranged at the retreat position side of the advancing/retreating member, away from an advancing/retreating movement axis of the advancing/retreating member, and
the biasing member is arranged at the retreat position side of the advancing/retreating member and accommodated in a space formed by the advance/retreat position control mechanism and the case.

### Claim 3 (depends on 2)

The advancing/retreating movement device according to claim 2, wherein the advance/retreat position control mechanism further comprises a plate-shaped guiding part that guides the restricting part, the advancing/retreating member is moved to an advance position and a retreat position by the restricting part being guided by the guiding part to an advance side position and a retreat side position, and
the guiding part is made to move so as to slide on the case when the advancing/retreating member moves to an advance position and a retreat position.
