ANGLE ADJUSTMENT DEVICE

To improve operability of an angle adjustment device.SOLUTION: An angle adjustment device 10 is provided that adjusts an inclination angle with respect to a support member 8, of an article 4 tiltably supported on the front side of the support member 8. The angle adjustment device 10 comprises: a cylindrical base member 20 provided in the support member; a shaft 21 which is inserted rotatably and forward immovably into an inner hole of the base member and comprises on the front end of the shaft 21, a male screw 51 threadedly engaging with a female screw hole 18 formed in the article 4; a gear member 22 which is unrotatably and forward immovably provided in the rear end of the shaft and includes a tooth row 55 arranged in an annular shape around the shaft in a part opposed to a rear end surface of the base member; and a restriction member 23 which engages with the base member and the gear member to restrict the backward movement of the gear member with respect to the base member.SELECTED DRAWING: Figure 1 【課題】 角度調節装置の操作性を向上させる。【解決手段】 支持部材８の前面側に傾斜可能に支持された物品４の支持部材に対する傾斜角を調節する角度調節装置１０であって、支持部材に設けられた筒形のベース部材２０と、ベース部材の内孔に回転可能かつ前方に移動不能に挿入され、その前端に物品４に形成された雌ねじ孔１８に螺合する雄ねじ５１を備えたシャフト２１と、シャフトの後端に回転不能かつ前方に移動不能に設けられ、ベース部材の後端面と対向する部分にシャフトを中心として環状に配列された歯列５５を含む歯車部材２２と、ベース部材及び歯車部材に係合することによってベース部材に対する歯車部材の後方への移動を規制する規制部材２３とを有する。【選択図】 図１
