Abstract

A hand unit for a timepiece, including: a hand for indicating time; and an attachment member including a support part attached to a rotational center of the hand so as to support the hand, and a cylindrical part defining a rotational axis of the hand and configured to be attached to a rotating shaft in the timepiece, the cylindrical part continuing from the support part extending towards a rear side of the timepiece along the rotational axis, wherein a bottom of the cylindrical part is at a position that is approximately the same or lower than a tip of the hand.

First claim

What is claimed is:

1 . A hand unit for a timepiece, comprising:
a hand for indicating time; and an attachment member including a support part attached to a rotational center of the hand so as to support the hand, and a cylindrical part defining a rotational axis of said hand and configured to be attached to a rotating shaft in the timepiece, the cylindrical part continuing from the support part extending towards a rear side of the timepiece along the rotational axis, wherein a bottom of the cylindrical part is at a position that is approximately the same or lower than a tip of the hand.

2 . The hand unit according to claim 1 ,
wherein the hand has a disk-shape profiled such that the rotational center of the hand is highest and the disk-shape becomes progressively lower towards the tip of the hand, and wherein the rotational center of the hand has a hole formed therein, and the support part is attached in the hole.

3 . A timepiece, comprising:
the hand unit according to claim 1 ; a hand movement unit including said rotating shaft that is inserted into the cylindrical part; and a timepiece case housing the hand unit and the hand movement unit.

4 . A timepiece, comprising:
the hand unit according to claim 2 ; a hand movement unit including said rotating shaft that is inserted into the cylindrical part; and a timepiece case housing the hand unit and the hand movement unit.

5 . The timepiece according to claim 3 , further comprising:
a thin hand that is thinner than the hand and attached above the hand, said thin hand slanted along a surface shape of the hand.

6 . The timepiece according to claim 4 , further comprising:
a thin hand that is thinner than the hand and attached above the hand, said thin hand slanted along a surface shape of the hand.

7 . The timepiece according to claim 3 , wherein a top of the rotating shaft is at a position that is approximately the same as a top of the attachment member.

8 . The timepiece according to claim 4 , wherein a top of the rotating shaft is at a position that is approximately the same as a top of the attachment member.

9 . The timepiece according to claim 5 , wherein a top of the rotating shaft is at a position that is approximately the same as a top of the attachment member.

10 . The timepiece according to claim 6 , wherein a top of the rotating shaft is at a position that is approximately the same as a top of the attachment member.
