Zusammenfassung:	To employ a mechanical system not requiring electric power and to unnecessitate a large torque in releasing a lock.SOLUTION: A lock mechanism 38 includes a casing 46 secured to a housing of a telescopic actuator, an input-side shaft 48 connected to a motor shaft of a motor and rotatably held in the casing 46, an output-side shaft 50 to which rotational torque is transmitted from the input-side shaft 48, and an engaging part 52. The engaging part 52 includes a pair of friction members 64, 64 displaceably provided along a guide groove 68, a claw part 60 having an acute shape in cross section and a side end part 58 which are provided on the input-side shaft 48, an abutting part 72 provided on each friction member 64, and a coil spring 70 for urging each friction member 64.SELECTED DRAWING: Figure 3 【課題】電力を不要としたメカ式を採用すると共に、ロック解除時に大きなトルクを不要とすること。【解決手段】ロック機構３８は、伸縮アクチュエータのハウジングに固定されるケーシング４６と、モータのモータ軸に連結され、ケーシング４６内に回転可能に保持された入力側シャフトと、入力側シャフトの回転トルクが伝達される出力側シャフト５０と、係止部５２とを備え、係止部５２は、ガイド溝６８に沿って変位可能に設けられた一対のフリクション部材６４、６４と、入力側シャフト４８に設けられた断面鋭角状爪部６０及び側端部５８と、フリクション部材６４に設けられた当接部７２と、各フリクション部材６４を付勢するコイルスプリング７０とを有する。【選択図】図３
