Abstract

An electric shaver according to the present disclosure includes: a body block having a holding portion; a head portion having a blade portion and supported on the body block to be swingable about a shaft portion; and a connecting member provided for connecting the body block and the head portion to each other. The connecting member is connected to the body block such that the connecting member is movable relative to the body block in an intersecting direction which intersects with an extending direction of the shaft portion, and the connecting member is also connected to the head portion by way of the shaft portion. The connecting member is connected to the body block by way of a resilient member. With such a configuration, it is possible to provide an electric shaver capable of suppressing the generation of abnormal sounds and vibrations while suppressing lowering of a swing performance.

First claim

What is claimed is:

1. An electric shaver comprising:
a body block having a holding portion;
a shaft portion;
a head portion having a blade portion and supported on the body block to be swingable about the shaft portion; and
a connecting member provided for connecting the body block and the head portion to each other, wherein:
the connecting member is connected to the body block such that the connecting member is movable relative, as relative movement, to the body block in an intersecting direction which intersects with an longitudinal direction of the shaft portion, and the connecting member is also connected to the head portion via the shaft portion,
the connecting member is connected to the body block via a resilient member,
a first gap which allows the relative movement of the connecting member to the body block in the intersecting direction is formed between the connecting member and the body block as viewed in the longitudinal direction of the shaft portion in a state where the connecting member is connected to the body block,
the resilient member is disposed in the first gap,
a first projecting portion which projects in the longitudinal direction of the shaft portion is formed on the connecting member, and a first through hole through which the first projecting portion is inserted is formed on the body block, at a position corresponding to the first projecting portion, and
the first gap is formed annularly around the first projecting portion in a state where the first projecting portion is inserted through the first through hole.

2. The electric shaver according to claim 1 , wherein the resilient member has a ring shape and is disposed over an entire inner circumference of the first gap formed annularly.

3. The electric shaver according to claim 1 , wherein
a second projecting portion which projects in the longitudinal direction of the shaft portion is formed on the connecting member, and a second through hole through which the second projecting portion is inserted is formed on the body block, at a position corresponding to the second projecting portion, and
a contact portion with which the second projecting portion is brought into contact when the connecting member is moved relative to the body block in the intersecting direction is formed on a peripheral portion of the second through hole.

4. The electric shaver according to claim 3 , wherein the second projecting portion include two pieces of projecting portions disposed on both sides of the resilient member as viewed in the longitudinal direction of the shaft portion.

5. The electric shaver according to claim 3 , wherein the second gap is formed around the second projecting portion in a state where the second projecting portion is inserted through the second through hole.

6. The electric shaver according to claim 5 , wherein a size of the second gap is smaller than a size of the first gap.
