To provide a rod expandable/contractable device capable of reducing a width of a case orthogonal to a drive shaft of a motor, to realize compactification in a width direction.SOLUTION: A rod extendable/contractable device 10 has a case 11, a rod 60 having an engaged part 67 on its outer periphery, a motor 70 having a drive shaft part 71, a gear 83 positioned on the tip side of the drive shaft part 71, and a lock retainer 90. The lock retainer 90 moves toward and away from the rod 60 by the drive shaft part 71. When the lock retainer moves toward the rod 60, a lock part 97 is engaged with the engaged part 67, and a portion between the motor 70 and the gear 83 is closest to the rod 60 when the rod 60 is viewed from an axial direction.SELECTED DRAWING: Figure 2 【課題】ケースの、モーターの駆動軸に対して直交する幅を小さくし、幅方向にコンパクト化を図れるロッド伸縮装置を提供する。【解決手段】このロッド伸縮装置１０は、ケース１１と、外周に被係合部６７を有するロッド６０と、駆動軸部７１を有するモーター７０と、駆動軸部７１の先端側に位置するギヤ８３と、ロックリテーナ９０とを有し、ロックリテーナ９０は、駆動軸部７１によりロッド６０に対して近接離反し、ロッド６０に対して近接移動したときに、ロック部９７が被係合部６７に係合し、ロッド６０を軸方向から見たときに、モーター７０とギヤ８３との間の部分が、ロッド６０に最も近接するように構成されている。【選択図】図２
